This will allow removing the winsys pointer from buffers.
The amdgpu winsys adds dummy_ws to get radeon_winsys because there can be
no radeon_winsys around (e.g. while amdgpu_winsys is being destroyed), but
we still need some way to call buffer functions.

It's straightforward except that the amdgpu winsys had to be cleaned up
to allow this.
radeon_cmdbuf is inlined and optionally the winsys can save the pointer
to it. radeon_cmdbuf::priv points to the winsys cs structure.

chroma_format depends on buffer_format so use the format_to_chroma_format
helper instead of storing it next to buffer_format.
This avoids bugs where one value is changed without updating the other.

Introduce a new driver-private transfer flag RADEON_TRANSFER_TEMPORARY
that specifies whether the caller will use buffer_unmap or not. The
default behavior is set to permanent maps, because that's what drivers
do for Gallium buffer maps.
This should eliminate the need for hacks in libdrm. Assertions are added
to catch when the buffer_unmap calls don't match the (temporary)
buffer_map calls.
I did my best to update r600 for consistency (r300 needs no changes
because it never calls buffer_unmap), even though the radeon winsys
ignores the new flag.
As an added bonus, this should actually improve the performance of
the normal fast path, because we no longer call into libdrm at all
after the first map, and there's one less atomic in the winsys itself
(there are now no atomics left in the UNSYNCHRONIZED fast path).

v2:
- remove comment about visible VRAM (Marek)
- don't rely on amdgpu_bo_cpu_map doing an atomic write

Now that Marek has split the two drivers apart, drop a bunch
of unnecessary code from the r600 half. There is probably a bunch
more hiding in the video code.
No piglit regressions on caicos.

This marks the end of code sharing between r600 and radeonsi.
It's getting difficult to work on radeonsi without breaking r600.
A lot of functions had to be renamed to prevent linker conflicts.
There are also minor cleanups.
