radeon: Fix crash when rendering to incomplete texture and other formats
It is possible to bind texture images of an incomplete mipmapped texture.
Software fallbacks in this case incorrectly tried to mmap the entire texture.
Additionally, add span functions for 1555 and 4444 formats.
This fixes crashes in piglit's fbo-readpixels test; unfortunately, the test
itself still fails - this needs to be investigated.

This updates some of the clear code from Intel gives a 5x clearspd perf
for me here. played openarena also, not sure if the viewport changes
broke anything,
tgsi: add semantic_names[] string for TGSI_SEMANTIC_FACE
Fixes TGSI dump output when front/back-face register is declared.
Also, add some assertions to make sure the semantic/interpolate string
arrays have as many elements as there are tokens in the p_shader_tokens.h
file. That should catch problems like this in the future.
mesa: From float type modifier from values to large for singles
The values 2147483648.0 and 4294967294.0 are too larget to be stored in single
precision floats. Forcing these to be singles causes bits to be lost, which
results in errors in some pixel transfer tests.
This fixes bug #22344.

glsl: do const parameter optimization for array element actual parameters
When a function parameter is const-qualified we can avoid making a copy
of the actual parameter (we basically do a search/replace when inlining).
This is now done for array element params too, resulting in better code
(fewer MOV instructions).
We should allow some other types of function arguments here but let's be
conservative for the moment.
mesa: only use fallback texture when using shaders, not fixed-function (take two)
The semantics are a little different for shaders vs. fixed-function when
trying to use an incomplete texture. The fallback texture returning
(0,0,0,1) should only be used with shaders. For fixed function, the texture
unit is truly disabled/ignored.
Fixes glean fbo test regression.

[anholt: squashed these two together from master, skipping the mess in between]
Of course glXGetVideoSyncSGI doesn't return the swap interval. The feature
only exists in the Mesa extension... which is the whole reason I created the
Mesa extension! Note that the Mesa extension allows drivers to default to a
swap interval of 0. If the Mesa extension exists, use its value. Only
consider the SGI extension when the Mesa extension is not available.
Fixes bug #22604.
wgl: Make the stw_framebuffer destructions threadsafe.
Ensure no other thread is accessing a framebuffer when it is being destroyed by
acquiring both the global and per-framebuffer mutexes. Normal access only
needs the global lock to walk the linked list and acquire the per-framebuffer
mutex.
wgl: Listen to WM_WINDOWPOSCHANGED instead of WM_SIZE messages.
According to
http://blogs.msdn.com/oldnewthing/archive/2008/01/15/7113860.aspx
WM_SIZE is generated from WM_WINDOWPOSCHANGED by DefWindowProc so it
can be masked out by the application.
Also there were some weird bogus WM_SIZE 0x0 messages when starting
sharedtex_mt which we don't get like this.
