Pull up CVS idents from FreeBSD to match our current version.
Update from FreeBSD: Split agp_generic_detach() up into two routines: agp_free_cdev() destroys /dev/agpgart and agp_free_res() frees resources like the BAR for the aperture. Splitting this up lets chipset-specific detach routines manipulate the aperture during their detach routines without panicing. Obtained-from: FreeBSD
Update the agp(4) code to the latest one from FreeBSD HEAD. This brings in a lot of newer hardware support. Obtained-from: FreeBSD
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>.

Fix malloc semantics (M_NOWAIT->M_INTWAIT/M_WAITOK).
This patch adds a bunch of stuff from FreeBSD5. It consistantly makes vendor specific drivers depend on agp, consistantly checks the gart size != 0, changes agp_generic_enable to the FreeBSD5 function, initializing the device as v2 or v3 accordingly, syncs up agpio.h, and adds a couple PCI Ids from FreeBSD5.

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/* should be regenerated from scratch.
Add the DragonFly cvs id and perform general cleanups on cvs/rcs/sccs ids. Most ids have been removed from !lint sections and moved into comment sections.
