glx/xlib: configurable strict/non-strict buffer size invalidate
Introduce a new configuration option XMESA_STRICT_INVALIDATE to switch
between swapbuffers-based and glViewport-based buffer invalidation.
Default strict invalidate to false, ie glViewport-based invalidation,
aka ST_MANAGER_BROKEN_INVALIDATE.
This means we will not call XGetGeometry after every swapbuffers,
which allows swapbuffers to remain asynchronous. For apps running at
100fps with synchronous swapping, a 10% boost is typical. For gears,
I see closer to 20% speedup.
Note that the work of copying data on swapbuffers doesn't disappear -
this change just allows the X server to execute the PutImage
asynchronously without us effectively blocked until its completion.
This applies even to llvmpipe's threaded rasterization as the
swapbuffers operation was a large part of the serial component of an
llvmpipe frame.
The downside of this is correctness - applications which don't call
glViewport on window resizes will get incorrect rendering, unless
XMESA_STRICT_INVALIDATE is set.
The ultimate solution would be to have per-frame but asynchronous
invalidation. Xcb almost looks as if it could provide this, but the
API doesn't seem to quite be there.

precompute texture setup as it should be done
- Unifies a bit more of code between nv30 and nv40
- Adds support for sampler view swizzles
- Support for specifying as sampler view format different from the
resource one (only trivially)
- Support for sampler view specification of first and last level
- Support for depth textures on nv30, both for reading depth and
for compare
- Support for sRGB textures
- Unifies the format table between nv30 and nv40
- Expands the format table to include essentially all supportable formats
except mixed sign and "autonormal" formats
- Fixes the "is format supported" logic, which was quite broken, and
makes it use the format table
Only tested on nv30 currently.

nvfx: new 2D: unify textures and buffers
Stop using the vtbl, and use real transfers for buffers too.

nvfx: new 2D: use a CPU copy for up to 4 pixels, up from 0
Seems a reasonable threshold for now.
Significantly speeds up Piglit's 1x1 glReadPixels (but, you know,
reading pixels in 1x1 blocks is NOT a good idea, especially if you
might be running on a less-than-perfect driver).

nvfx: new 2D: new render temporaries with resources
This patch adds support for creating temporary surfaces to allow
rendering to surfaces that cannot be rendered to.
It uses the _second_ version of the render temporary infrastructure.
This is necessary for swizzled 3D textures and small mipmaps of
swizzled 2D textures.
This version of the patch creates a resource to use as a temporary
instead of a raw BO, making the code simpler.

nv30: new 2D: support ARB_texture_rectangle
This uses nv30's _RECT formats.
