9ca6cf0f54 tgsi: convert CHECK_INF_OR_NAN to inline function 
And disable with if (0).  Inf/NaN can occur normally during program
execution.  Only enable the check code when needed during debugging.

2ec50d256d mesa: Factor out the fb initialization details from _mesa_new_framebuffer. 
This should make things easier for drivers wanting to work with a
"subclass" of gl_framebuffer.

The complementary "_mesa_initialize_framebuffer" function is now
called "_mesa_initialize_window_framebuffer" for the sake of
symmetry.

db0eb3a437 vbo: Fix up in-place splitting for non-contiguous/indexed primitives. 
The in-place splitting code wasn't dealing with index buffers at all
(and it was being called from vbo_split_prims for too big index
buffers, causing some occasional corruption).

Additionally, it wasn't taking into account primitives arrays with
non-contiguous indices (e.g. given prim[0].start = 0 and prim[1].start
= max_verts, it would happily call back the driver with (max_index -
min_index) still greater than max_verts, causing infinite recursion).

It still doesn't handle too large indexed vertex buffers: use
vbo_split_copy for that.

a9cdae2ae0 svga: texture from lod zero inside dynamic branching 
Texture derivatives are potentially undefined inside dynamic branches,
so hardwire lod zero in this case.  Treating all if/endif and loop
constructs as dynamic branches.

9b23e1f9a3 mesa/st: bump the gallium version number

0d089cbb48 egl: Rename _eglPreloadForEach callbacks. 
Rename _eglPreloadFile to _eglLoaderFile, and _eglPreloadFile to
_eglLoaderFile.  There are several _eglPreload* functions.  The
callbacks do not belong to them and it should be better to give them a
different prefix.

5d8646c41f egl: Add EGL_DRIVERS_PATH environment variable. 
EGL_DRIVERS_PATH gives a list of colon-separated directories.  The given
directories will be searched when preloading drivers.

This is based on Mike Stroyan's patch, which honors the variable in
_eglPreloadDisplayDrivers.  It is extended to honor the variable also in
_eglPreloadUserDriver and _eglPreloadDefaultDriver in this version.
