FreeBSD. Add drm_get_resource_{start|len} so linux-specific stuff
doesn't need to be in shared code.
- Fix mach64 build by using __DECONST to work around passing a const
pointer to useracc, which is unfortunately not marked const.
- Get rid of a lot of maplist code by not having dev->maplist be a pointer,
and by sticking the link entries directly in drm_local_map_t rather
than having a separate structure for the linked list.
- Factor out map uninit and removal into its own routine, rather than
duplicating in both drm_takedown() and drm_rmmap().
- Hook up more driver functions, and correct FreeBSD-specific bits of
radeon_cp.c, making radeon work.
- Baby steps towards using bus_space as we should.

ioctls with dev_lock, which is a major step toward being able to remove
Giant. Covers some new pieces (dev->unique*) in the core, and avoids
one call down into system internals with the drm lock held, which is
usually bad (FreeBSD LOR #23, #27).

using drm_alloc/drm_free in the core and instead use plain malloc/free.

doesn't run yet. Moves the ioctl definitions for these two drivers back
to the shared code -- they aren't OS-specific.

effects, so make them look like functions (add parenthesis).

Change some nearby memset()s to bzero()s or to calloc allocations to
take advantage of M_ZERO). Reverse some error tests to reduce high
levels of indentation. Move the sg_cleanup() call out of the maplist
loop in DRM(takedown)-- I can't see any need for it to be inside.

allocate framebuffer memory without sisfb, and a new ioctl to be used
by the X Server which tells the DRM what region of framebuffer memory
to allocate from. Also fixes a possibility to panic the kernel I
believe. Tested on linux with sisfb and FreeBSD (without sisfb) with
new DRI only.

done through perforce.
- Add copyright headers to drm_os_*bsd.h, still need to research the other
copyright-less files better.

future.

DRM(write_string). This is the first part of removing much of the
support code for gamma from the BSD DRM, since it appears that no new
drivers are using it and nobody has ever shown interest in gamma on
BSD.

merging. Also includes an update to radeon PCI IDs.
