According to the GLX_MESA_query_renderer spec each driver should
be able to report the version of each GL api they support before
creating a context.
Currently both classic mesa and gallium evaluate the version post
context creation and while the classic drivers set the max_gl*version
according to their capabilities, gallium uses fixed values which
are not the best approach due to driver differences.
Add pipe-caps so that each driver can provide their individual capabilites.
