This adds the glXCreateContextAttribsARB() function for the xlib/swrast

For example, without this patch we get:

piglit: info: Failed to create any GL context
PIGLIT: {"result": "skip" }
Fwiw I believe that the 'issue' is within piglit. Namely, waffle
follows glx/wgl semantics which dictate that if you want to specify
the version of the context during creation you need the
*ARB_create_context extension. Perhaps piglit should fall-back to
creating the context without mentioning the version, and checking it
afterwords ?
I'll see if I can cook up a fix for that, as this approach feels a bit hackish.
Sounds good. I think piglit/waffle could just glXCreateContext() if the
version is <= 30.
