gallium: add timeout parameter to fence_finish
This is a follow-up to the ARB_sync patch for st/mesa and completes
the ARB_sync implementation.

st/mesa: implement ARB_sync
The ServerWaitSync implementation matches Intel's driver.
The extension is advertised when pipe_screen::fence_finish is set.

gallium/util: add LATC support
Again, a lot of code is shared with RGTC.
The layout is UTIL_FORMAT_LAYOUT_RGTC, because LATC is just swizzled RGTC.

mesa: add ATI_texture_compression_3dc
LUMINANCE_ALPHA_LATC2 = LUMINANCE_ALPHA_3DC, so this is easy.
Note that there is no specification for 3DC, just a few white papers
from ATI.

mesa: add EXT_texture_compression_latc
The encoding/decoding algorithms are shared with RGTC.
Thanks to some magic with the base format, the RGTC texstore functions work
for LATC too.
swrast passes the related piglit tests besides two things:
- The alpha channel is wrong (it's always 1), however the incorrect alpha
channel makes some other tests fail too, so I guess it's unrelated to LATC.
- Signed LATC fetches aren't correct yet (signed values are clamped to [0,1]),
however RGTC has the same problem.
Further testing (with other of my patches) shows that hardware drivers
and softpipe work.
BTW, ETQW uses this extension.

st/mesa: Fix an incorrect user vertex buffer reference
st->user_vb[attr] was always pointing to the same user vb, regardless
of the value of attr. Together with reverting the temporary workaround
for bug 34378, and a fix in the svga driver, this fixes googleearth on svga.
