Sync CAM with FreeBSD using lockmgr locks instead of mutexes.
Note:  This is mostly a code sync with FreeBSD which improves stability
in addition to the items listed below.  This provides a framework for
releasing the mplock, but for now it's still there.

Add an xpt_print function to reduce most of the xpt_print_path/printf
pairs. Convert the core code to use it.

Initial cut at Basic Domain Validation.

Make cam_xpt's pronouncements match camcontrol (Tagged -> Command) Queueing.

Pay attention to return value from xpt_bus_register in xpt_init.

Add an xpt_rescan function and a thread that will field rescan requests.
The purpose of this is to allow a SIM (or other entities) to request a bus
rescan and have it then fielded in a different (process) context from the
caller.

Check the return value from cam_periph_acquire.

Drop the periph/sim lock when calling disk_destroy().

Drop the topology lock before calling the periph oninvalidate and dtor
vectors.

For the XPT_SASYNC_CB operation, only decouple the broadcast to the bus
and device lists instead of decoupling the whole operation.  This avoids
problems with SIMs going away.

Split the camisr into per-SIM done queues.  This optimizes the locking a
little bit and allows for direct dispatch of the doneq from certain
contexts that would otherwise face recursive locking problems.

Zero the CCBs when mallocing them.

Only schedule the xpt_finishconfig_task once.

Eliminate the use of M_TEMP.

Add a helper function for registering async callbacks.

Release the bus reference that is acquired when doing a CAMIOCOMMAND ioctl.

Zero scsi_readcapacity allocations so we can really tell if there has
been data returned.

Remove duplicate includes and fix typos.

Add a bunch of definitions and structures to support newer drivers.

When probing a newly found device, don't automatically assume that the
device supports retrieving a serial number.  Instead, first query the
list of VPD pages it does support, and only query the serial number if
it's supported, else silently move on.  This eliminates a lot of noise
during verbose booting, and will likely eliminate the need for most
NOSERIAL quirks.

Reduce diffs from FreeBSD.

Fixes for CAM_NEW_TRAN_CODE.

This commit is taken from a FreeBSD changeset, and is not intended to

CAM_NEW_TRAN_CODE option, but this opens the door for wider testing.

Give the device major / minor numbers their own separate 32 bit fields
in the kernel.  Change dev_ops to use a RB tree to index major device
numbers and remove the 256 device major number limitation.

Build a dynamic major number assignment feature into dev_ops_add() and
adjust ASR (which already had a hand-rolled one), and MFS to use the
feature.  MFS at least does not require any filesystem visibility to
access its backing device.  Major devices numbers >= 256 are used for
dynamic assignment.

Retain filesystem compatibility for device numbers that fall within the
range that can be represented in UFS or struct stat (which is a single
32 bit field supporting 8 bit major numbers and 24 bit minor numbers).

Do a major clean-up of the BUSDMA architecture.  A large number of
essentially machine-independant drivers use the structures and definitions
in machine-dependant directories that are really machine-independant in
nature.

Split <machine/bus_dma.h> into machine-depdendant and machine-independant parts
and make the primary access run through <sys/bus_dma.h>.

Remove <machine/bus.h>, <machine/bus_memio.h> and <machine/bus_pio.h>.  The
optimizations related to bus_memio.h and bus_pio.h made a huge mess,
introduced machine-specific knowledge into essentially machine-independant
drivers, and required specific #include file orderings to do their job.
They may be reintroduced in some other form later on.

Move <machine/resource.h> to <sys/bus_resource.h>.  The contents of the file
is machine-independant or can be made a superset across many platforms.

Make <sys/bus.h> include <sys/bus_dma.h> and <sys/bus_resource.h> and
include <sys/bus.h> where necessary. Remove all #include's of
<machine/resource.h> and <machine/bus.h>.  That is, make the BUSDMA
infrastructure integral to I/O-mapped and memory-mapped accesses to devices
and remove a large chunk of machine-specific dependancies from drivers.
bus_if.h and device_if.h are now required to be present when using <sys/bus.h>.

Further normalize the _XXX_H_ symbols used to conditionalize header file
inclusion.

Use _MACHINE_BLAH_H_ for headers found in "/usr/src/sys/arch/<arch>/include".
Most headers already did this, but some did not.

Use _ARCH_SUBDIR_BLAH_H_ for headers found in "/usr/src/sys/arch/<arch>/subdir"
instead of _I386_SUBDIR_BLAH_H_.

Change #include's made in architecture-specific directories to use
<machine/blah.h> instead of "blah.h", allowing the included header files
to be overrdden by another architecture.  For example, a virtual kernel
architecture might include a header from arch/i386/include which then
includes some other header in arch/i386/include.  But really we want that
other header to also go via the arch/vkernel/include, so the header files
in arch/i386/include must use <machine/blah.h> instead of "blah.h" for most
of their sub-includes.

Change most architecture-specific includes such as <i386/icu/icu.h> to
use a generic path through the "arch" softlink, such as <arch/icu/icu.h>.

Remove the temporary -I@/arch shim made in a recent commit, the <arch/...>
mechanism replaces it.

These changes allow us to implement heirarchical architectural overrides,
primarily intended for virtual kernel support.  A virtual kernel uses an
architecture of 'vkernel' but must be able to access actual cpu-specific
header files such as those found in arch/i386.  It does this using a
"cpu" softlink.  For example, someone including <machine/atomic.h> in a
vkernel build would hit the "arch/vkernel/include/atomic.h" header, and this
header could then #include <cpu/atomic.h> to access the actual cpu's
atomic.h file: "arch/i386/include/atomic.h".

The ultimate effect is that an architecture can build on another
architecture's header and source files.

MASSIVE reorganization of the device operations vector.  Change cdevsw
to dev_ops.  dev_ops is a syslink-compatible operations vector structure
similar to the vop_ops structure used by vnodes.

Remove a huge number of instances where a thread pointer is still being
passed as an argument to various device ops and other related routines.
The device OPEN and IOCTL calls now take a ucred instead of a thread pointer,
and the CLOSE call no longer takes a thread pointer.

Note that doreti uses a temporary CPL mask internally to accumulate a bitmap
of FAST interrupts which could not be executed due to not being able to get

Get rid of bus_{disable,enable}_intr(), it wasn't generic enough for
our needs.

Implement some generic atomic.h functions to aid in the implementation of
a low level mutex.

Implement a generic low level sleep-mutex serializer, kern/lwkt_serialize.c.
The serializer is designed to be a replacement for SPL calls but may also
be used for other very low level work (e.g. lockmgr interlocks).

Add a serializer argument to BUS_SETUP_INTR().  When non-NULL, the interrupt
handler will no longer be protected by an SPL so e.g. spl*() will no
longer protect against that device's interrupts.

The IF queueing and dequeueing mechanisms may no longer depend on outside
SPL state because network driver interrupt handlers are no longer required to
enter splnet().  Use critical sections for the moment.  The IFQ and
IFF_OACTIVE interactions are not yet MP safe.

Device layer rollup commit.

* cdevsw_add() is now required.  cdevsw_add() and cdevsw_remove() may specify
  a mask/match indicating the range of supported minor numbers.  Multiple
  cdevsw_add()'s using the same major number, but distinctly different
  ranges, may be issued.  All devices that failed to call cdevsw_add() before
  now do.

* cdevsw_remove() now automatically marks all devices within its supported
  range as being destroyed.

* vnode->v_rdev is no longer resolved when the vnode is created.  Instead,
  only v_udev (a newly added field) is resolved.  v_rdev is resolved when
  the vnode is opened and cleared on the last close.

* A great deal of code was making rather dubious assumptions with regards
  to the validity of devices associated with vnodes, primarily due to
  the persistence of a device structure due to being indexed by (major, minor)
  instead of by (cdevsw, major, minor).  In particular, if you run a program
  which connects to a USB device and then you pull the USB device and plug
  it back in, the vnode subsystem will continue to believe that the device
  is open when, in fact, it isn't (because it was destroyed and recreated).

  In particular, note that all the VFS mount procedures now check devices
  via v_udev instead of v_rdev prior to calling VOP_OPEN(), since v_rdev
  is NULL prior to the first open.

* The disk layer's device interaction has been rewritten.  The disk layer
  (i.e. the slice and disklabel management layer) no longer overloads
  its data onto the device structure representing the underlying physical
  disk.  Instead, the disk layer uses the new cdevsw_add() functionality
  to register its own cdevsw using the underlying device's major number,
  and simply does NOT register the underlying device's cdevsw.  No
  confusion is created because the device hash is now based on
  (cdevsw,major,minor) rather then (major,minor).

  NOTE: This also means that underlying raw disk devices may use the entire
  device minor number instead of having to reserve the bits used by the disk
  layer, and also means that can we (theoretically) stack a fully
  disklabel-supported 'disk' on top of any block device.

* The new reference counting scheme prevents this by associating a device
  with a cdevsw and disconnecting the device from its cdevsw when the cdevsw
  is removed.  Additionally, all udev2dev() lookups run through the cdevsw
  mask/match and only successfully find devices still associated with an
  active cdevsw.

* Major work on MFS:  MFS no longer shortcuts vnode and device creation.  It
  now creates a real vnode and a real device and implements real open and
  close VOPs.  Additionally, due to the disk layer changes, MFS is no longer
  limited to 255 mounts.  The new limit is 16 million.  Since MFS creates a
  real device node, mount_mfs will now create a real /dev/mfs<PID> device
  that can be read from userland (e.g. so you can dump an MFS filesystem).

* BUF AND DEVICE STRATEGY changes.  The struct buf contains a b_dev field.
  In order to properly handle stacked devices we now require that the b_dev
  field be initialized before the device strategy routine is called.  This
  required some additional work in various VFS implementations.  To enforce
  this requirement, biodone() now sets b_dev to NODEV.  The new disk layer
  will adjust b_dev before forwarding a request to the actual physical
  device.

* A bug in the ISO CD boot sequence which resulted in a panic has been fixed.

Testing by: lots of people, but David Rhodus found the most aggregious bugs.

The cam_sim structure was being deallocated unconditionally by device
driver detach routines.  The problem with this is that part of the CAM
bus structure may still be active (for example, with pending timeout()'s),
and even though the bus, target, and device is freed, since the sim IS
freed any accesses through the sim will hit 0xdeadc0de.  This case most often
occurs with USB UMASS devices.

kernel tree reorganization stage 1: Major cvs repository work (not logged as
commits) plus a major reworking of the #include's to accomodate the
relocations.

    * CVS repository files manually moved.  Old directories left intact
      and empty (temporary).

    * Reorganize all filesystems into vfs/, most devices into dev/,
      sub-divide devices by function.

    * Begin to move device-specific architecture files to the device
      subdirs rather then throwing them all into, e.g. i386/include

    * Reorganize files related to system busses, placing the related code
      in a new bus/ directory.  Also move cam to bus/cam though this may
      not have been the best idea in retrospect.

    * Reorganize emulation code and place it in a new emulation/ directory.

    * Remove the -I- compiler option in order to allow #include file
      localization, rename all config generated X.h files to use_X.h to
      clean up the conflicts.

    * Remove /usr/src/include (or /usr/include) dependancies during the
      kernel build, beyond what is normally needed to compile helper
      programs.

    * Make config create 'machine' softlinks for architecture specific
      directories outside of the standard <arch>/include.

    * Bump the config rev.

    WARNING! after this commit /usr/include and /usr/src/sys/compile/*

DEV messaging stage 1/4: Rearrange struct cdevsw and add a message port
and auto-queueing mask.  The mask will tell us which message functions
can be safely queued to another thread and which still need to run in the
context of the caller.   Primary configuration fields (name, cmaj, flags,
port, autoq mask) are now at the head of the structure.  Function vectors,
which may eventually go away, are at the end.  The port and autoq fields
are non-functional in this stage.

The old BDEV device major number support has also been removed from cdevsw,
and code has been added to translate the bootdev passed from the boot code
(the boot code has always passed the now defunct block device major numbers
and we obviously need to keep that compatibility intact).

proc->thread stage 2: MAJOR revamping of system calls, ucred, jail API,
and some work on the low level device interface (proc arg -> thread arg).
As -current did, I have removed p_cred and incorporated its functions
into p_ucred.  p_prison has also been moved into p_ucred and adjusted
accordingly.  The jail interface tests now uses ucreds rather then processes.

The syscall(p,uap) interface has been changed to just (uap).  This is inclusive
of the emulation code.  It makes little sense to pass a proc pointer around
which confuses the MP readability of the code, because most system call code
will only work with the current process anyway.  Note that eventually
*ALL* syscall emulation code will be moved to a kernel-protected userland
layer because it really makes no sense whatsoever to implement these
emulations in the kernel.

suser() now takes no arguments and only operates with the current process.
The process argument has been removed from suser_xxx() so it now just takes
a ucred and flags.

The sysctl interface was adjusted somewhat.
