dlopen manpage mandates that either RTLD_LAZY or RTLD_NOW flags must be
passed. Not doing so was causing a NULL return on debian unstable x86-64.

For non-stereo visuals, which is all we support, we treat
GL_FRONT_LEFT as GL_FRONT. However, they are technically different,
and they have different enum values. Test for either one to determine
if we're in front-buffer rendering mode.
This fix was suggested by Pierre Willenbrock.

Before we always created the front color buffer, even if was never used.
This can save some memory.

When a GLSL sampler reads from an incomplete texture it should
return (0,0,0,1). Instead of jumping through hoops in all the drivers
to make this happen, just create/install a fallback texture with those
texel values.
Fixes piglit/fp-incomplete-tex on i965 and more importantly, fixes some
GPU lockups when trying to sample from missing surfaces. If a binding
table entry is NULL, it seems that sampling sometimes works, but not
always (lockup).
Todo: create a fallback texture for each type of texture target?

It is no longer optional in current libdrm, so it was time to actually
start counting our BOs.

Make things more consistent, prepare for more function hooks.

We'll just forever leave it in r300_winsys.h since it's needed for
whichever winsys is hosting the pipe.

Fixes a use-after-free reported in
http://bugs.freedesktop.org/show_bug.cgi?id=20539, so this possibly fixes that
bug. It has been confirmed to fix

I don't think anyone besides a developer would ever want to use the demo
egl driver. Furthermore, egl would only ever load demodriver if it was
set via EGL_DRIVER in the environment. In that case, I think you can
point it to your mesa source directory.

Previously the pkg-config output files would contain e.g. `-lGL'
and `-lGLU', even if the user modified their configuration to
build libraries with different names. This modifies the
pkg-config inputs, and corresponding makery, so that modifying the
output library name will cause the appropriate updated name to
appear in the pkg-config `-l' option.

This function will check an instruction to see if there's data dependencies
between the dst and src registers if executed in an SOA manner.

The TGSI interpeter operates in SOA style. We need to check for data
dependencies in instructions which read from and write to the same register.
For now just adding some debug code to detect that condition. Actual fixes
to follow.

This allows the engine demo to run again (avoid crash in VBO code).
This stuff still needs to be revisited someday though...

It seems quake4 can hit these attributes sometimes.

Proper fix for this hasn't been identified, but avoid crashing.

Less TLS lookups.

This is only used for debuging the gem backend on i965
chipset using the softpipe pipe driver.
Usage: "export INTEL_SOFTPIPE=y" and point LIBGL_DRIVERS_PATH
to "$MESA/lib/gallium" where $MESA is the mesa root.

If a shader reaches an out-of-memory condition while adding
a new function (reallocating the function list), a segfault
will occur during cleanup (because the num_functions field
is non-zero, but the functions pointer is NULL).
This fixes that segfault by zeroing out the num_functions
field if reallocation fails.

DllMain is called with DLL_THREAD_ATTACH only by threads created after
the DLL is loaded by the process.
