tests/glx: Add unit tests for GLX_ARB_create_context GLX protocol

This adds a new tests directory at the top-level and some extra build
infrastructure.  The tests use the Google C++ Testing Framework, and
they will only be built if configure can detect its availability.  The
tests are automatically wired-in to run with 'make check'.
