DMA lock in a non-DMA driver, as it will be uninitialized.

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).

martinlexa dot cz). Now that we've got porting for all three major BSDs
(and the fourth being very similar to FreeBSD), move the
mostly-duplication drm_os_* files into drmP.h. Remove some cruft from
linux heritage and from pieces of the DRM that have since been removed.
Note that things are still not quite working for even FreeBSD, but these
are first steps at cleanup, and just a WIP checkpoint.

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

get the drm_file_t * based on the filp passed in ioctl handlers.
- Use this macro on BSD for simplification and improve its error reporting.
Make failure to find the drm_file_t * print as an error, not debug.
This failure may be part of the problem with KDE.
- Make debug and error print macros include the pid on BSD.

used by root (the X Server) which are not locked. However, it should
deal with lost-IRQ issues on -current which I think people have been
experiencing but I am unable to reproduce (though I understand why they
would occur, because of a bug of mine). Note that most of the locking
(DRM_LOCK()/UNLOCK()) is all covered by Giant still, so it doesn't
matter yet.
- Remove locking on FreeBSD-stable and NetBSD. These are covered by the
fact that there is no reentrancy of the kernel except by interrupts,
which are locked using spldrm()/splx() instead.

I've touched enough of the code here, and there was no previous
copyright. Do some drive-by style fixes while I'm here.

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