If a fragment program only parameter was queried of a vertex program
(e.g., GL_MAX_PROGRAM_TEX_INDIRECTIONS_ARB) no error would be set and
a random value would be returned. This caused 'glxinfo -l' to show
the same values for GL_MAX_PROGRAM_ALU_INSTRUCTIONS_ARB,
GL_MAX_PROGRAM_TEX_INSTRUCTIONS_ARB, GL_MAX_PROGRAM_TEX_INDIRECTIONS_ARB,
GL_MAX_PROGRAM_NATIVE_ALU_INSTRUCTIONS_ARB,
GL_MAX_PROGRAM_NATIVE_TEX_INSTRUCTIONS_ARB,
GL_MAX_PROGRAM_NATIVE_TEX_INDIRECTIONS_ARB as for
GL_MAX_PROGRAM_ENV_PARAMETERS_ARB. This is confusing and incorrect.
When a single-buffered window was resized the new window size was never
detected. This fix that, but there's still a bug which causes window
contents corruption for certain window sizes...
When adding a new bitmap to the cache we have to check if the Z value is
changing and flush first if it is.
This is a modified version of a patch from Justin Dou <justin.dou@intel.com>
egl_xdri does not compile for some time. This commit revives the
driver. It no longer depends on libGL.so for GLX related functions.
Instead, it uses code from src/glx/ directly. Both DRI and DRI2 are
supported.

There is a possbile race that _glapi_Context is reset by another thread
after it is tested in GET_CURRENT_CONTEXT but before it is returned. We
definitely do not want a lock here to solve the race. To have correct
results even under a race, no other threads should reset _glapi_Context
(or _glapi_Dispatch).
This patch adds a new global variable _glapi_SingleThreaded. Since
_glapi_Context or _glapi_Dispatch are no longer reset,
_glapi_SingleThreaded is tested instead, before accessing them.
DRI drivers compiled with this patch applied will not work with existing
libGL.so because of the missing new symbol. If this turns out to be a
real problem, this patch should be reverted.

If multiple threads set/get a TSD at roughly same time for the first
time, glthread might (wrongly) initialize it more than once. This patch
solves the race by initializing context/dispatch TSDs early.

Multiple threads might call _glapi_check_multithread at roughly the same
time. It is possbile that all of them are wrongly regarded as firstCall
if there is no mutex. This bug causes xeglthreads to crash sometimes.

When translating an incoming shader (rather than building one from scratch)
it's preferable to be able to call a single, generic instruction emitter
rather than figuring out which of the opcode-specific functions to call.
Not doing so seems to cause lock-ups or rendering problems
on some chips. I think there is an logic issue related to
CB and VGT on some chips. We ran into similar issues in
r600_demo IIRC.
This patch fixes some "implicit declaration of function" compilation
errors/warnings on the new shader code.
