WARNS6 cleanup (1803 warnings).

ANSI function declarations.

Staticize functions.

Rename local variables that shadow globals.

Use string functions from libc instead of creating our own.

Remove void casts for unchecked function returns.

Spell parameter correctly.

Don't try to return a value from void functions.

Remove compat library requirement (gtty -> ioctl).

Add new function "dowarp" that calls warp() from play.c.  (Taken from
NetBSD).

Change chars that are used for numeric values to shorts so they can be
properly used as array indexes.

**  Global Declarations
**
**	Virtually all non-local variable declarations are made in this
**	file.  Exceptions are those things which are initialized, which
**	are defined in "externs.c", and things which are local to one
**	program file.
**
**	So far as I know, nothing in here must be preinitialized to
**	zero.
**
**	You may have problems from the loader if you move this to a
**	different machine.  These things actually get allocated in each
**	source file, which UNIX allows; however, you may (on other
**	systems) have to change everything in here to be "extern" and
**	actually allocate stuff in "externs.c"
