[Piglit] [PATCH 00/29] Dispatch support for EGL and GLES

[Pauli Nieminen]

Following changes make it possible to use dispatch based function resolving
for GLES and EGL core and extensions functions.

The function prototypes and defines are parsed from system headers if they are
present during compilation. Because data is parsed using regular expressions
from C header fails it is possible that special cases like eglGetProcAddress
might be missed by generalized regular expression. Those special cases will
require custom parsing if we find any more of problematic lines.

There is also some minor improvements to egl and gles utility functions to help
runtime detection of supported features in tests.

The patches are "waffle ready" meaning that there is some differences what is done if piglit is compiled using waffle to support runtime selection of EGL/GLX and GL api.

I did run quick tests set on i965 to check for regressions. To bad it appears
that piglit can hit random failures before and after. I tried to reproduce
random failures manually but failed so far.

I already saw once random failure when I was running bisectability tests on
small set of tests. In that case it appeared like some rendering didn't hit the
target memory before glReadPixels. But I couldn't reproduce the issues with
while <test>; do sleep 0; done.
