The envvar works for R100 and R200 too, and the classic R300 driver
doesn't even exist anymore.
"RADEON_NO_TCL" is already mentioned in the code and is the same envvar
used for the R300g driver.
Override the context's GLSL version if the environment variable
MESA_GLSL_VERSION_OVERRIDE is set. Valid values for
MESA_GLSL_VERSION_OVERRIDE are integers, such as "130".
MESA_GLSL_VERSION_OVERRIDE has the same behavior as INTEL_GLSL_VERSION,
except that it applies to all drivers, not just Intel's. Since the former
supercedes the latter, this patch disables the latter.

It is necessary to manually set the GL version to 3.0 in order to run
Piglit tests that use glGetUniform*().
This patch allows one to override the version of the OpenGL context by
setting the environment variable MESA_GL_VERSION_OVERRIDE.

If set to year X, only report extensions up to that year. This is a
work-around for games that try to copy the extensions string to a fixed
size buffer and overflow. If a game was released in year X, setting
MESA_EXTENSION_MAX_YEAR to that year will likely fix the problem.
