I had a colleague hitting issues compiling with an old gcc3.2
system. These patches got them through.
NOTE: This is a candidate for the 7.11 branch.

Use VRAM for static and immutable buffers. This restores the
recently removed r600g winsys behaviour for memory locations.
This also improoves rendering times on the gpu for some
OpenSceneGraph based test cases by about 15%.

Make sure we do not run into the classic ABA problem on buffer object bind,
reusing this name and may be never rebind since we get an new name
that was just deleted and never rebound in between.
The explicit rebinding to the debault object in the current context
prevents the above in the current context, but another context
sharing the same objects might suffer from this problem.

Buffer objects may be shared across contexts.
Rework the array attrib push/pop implementation
to be thread safe. Make use of more library functions
for this purpose.

In the past, swrast_texture_image::Data has been overloaded. It could
either point to malloc'd memory storing texture data, or it could point
to a current mapping of GPU memory.
Now, Buffer always points to malloc'd memory (if we're not using GPU
memory) and Data always points to mapped memory. The next step would
be to rename Data -> Map.
This change also involves adding swrast functions for mapping textures
and renderbuffers prior to rendering to setup the Data pointer. Plus,
corresponding functions to unmap texures and renderbuffers. This is
very much like similar code in the dri drivers.
Only swrast and the drivers that fall back to swrast need these fields now.
This removes the last of the fields related to software rendering from
gl_texture_image.
In lp_build_stencil_op() the incoming 'stencil' var is a 2-element array.
There's a front-face writemask and a back-face writemask but we're ignoring
the later. This patch doesn't fix anything but at least points out the
problem.
v2: Avoid the C99 rounding functions, because I don't trust
get/setting the C99 rounding mode from inside our library not having
other side effects. Instead, open-code roundEven() behavior around
Mesa's IROUND, which we're already testing for C99 rounding mode
safety.

- Fix _GNUC__ typo in both checks
- Fix logic error in check for gcc < 3.4 that breaks for gcc 2.x & older
Without this fix, builds with gcc 3.4.x end up depending on undefined
_mesa_bitcount instead of gcc's __builtin_popcount.
NOTE: This is a candidate for the stable branches.

Should fall back to shader based decoding (g3dvl) for now.
This is probably broken on systems that support xvmc, because
nouveau_video_buffer_create has no way to know for what api
the buffer is created, so I think this call might need a
separate argument as workaround.
