Among other benefits, parallel makes now work. Since many people have
parallel builds by default (via MAKEFLAGS environment variable), this
sames some irritation at release time...when there's usually not any
other irritation already.
In my last commit I introduced a build dependency upon a new libdrm.
Add the associated autoconf checks. As the headers are part of the core
libdrm, we need to bump that version and so may as well bump the chipset
specific versions simultaneously.

With relaxed relocation checking in the kernel, we can specify a
negative delta (i.e. pointing outside of the target bo) in order to fake
a range in a large buffer. We only then need to upload the elements used
and adjust the buffer offset such that they correspond with the indices
used in the DrawArrays.

... and take advantage of start_vertex_bias to trim to [min_index,
max_index] where possible (i.e. when we need to upload all arrays).
Fixes half_float_vertex(misc.fillmode.wireframe)

When doing copy swapbuffers using drm, throttle on outstanding copy operations.
Introduces a new environment variable, EGL_THROTTLE_FENCES that the
user can use to indicate the desired number of outstanding swapbuffers, or
disable throttling using EGL_THROTTLE_FENCES=0.
This can and perhaps should be extended to the pageflip case as well, since
with some hardware pageflips can be pipelined. In case the pageflip syncs, the
throttle operation will be a no-op anyway.

Use the pageflip ioctl when available.
Otherwise, or when the backbuffer contents need to be preserved,
fall back to a copy operation.

The copy swap can be used when we need to preserve the contents of
the back buffer or when there is no way to do native page-flipping.

This makes it usable also for native helpers.
Also add inline functions to access the context and to
uninit the native display structure.

This is reliant on a drm patch that I posted on the list + a version bump.
These will appear in drm-next today.

If the drm minor version is > 9 (i.e. whats in drm-next),
we enable s3tc + texture tiling by default now.
this changes R600_FORCE_TILING to R600_TILING which can
be set to false to disable tiling on working drm.

By default the hardware rounds texcoords. However,
for point sampled textures, the expected behavior is
to truncate. When we have point sampled textures,
set the truncate bit in the sampler.
Should fix:

No idea why I didn't do it like this the first time, but share
the code like other portions of mesa do using _tmp.h suffix
and some #defines for the types.

The other draw stages like aaline and pstipple were already doing this.
If the driver used the aapoint stage but not the others it would crash
because of a null pipe->draw pointer.
It was only implemented in the swrast driver and probably not used by
any applications. A modern app would use a dependent/chained texture
lookup in the fragment shader.
when doing glCopyTex[Sub]Image() and checking the source buffer's
completeness.
We only need to determine FBO completeness when the status is indeterminate.
