[Piglit] [PATCH 22/35] framework/profile: Add support for meta profiles

[Dylan Baker]

MetaProfiles are a single profile composed of more than one profile.
This is designed to allow the old all-inclusive names to continue to
exist without having to keep duplicates of each profile around. A
metaprofile simply declares that it needs profiles a, b, and c and then
runs those.

This allows an "all" meta profile to include opengl, shader, and
glslparser, for example.

A metaprofile is allowed to include XML or python based profiles.
