Subject: [PATCH 03/11] glx: Extend __GLXscreen::createContext to take attributes
The attributes will be used for glXCreateContextAttribsARB additions
in follow-on patches.
v2: Add missing 'int *error' parameters noticed by Christopher James
Halse Rogers.
v3: Remove redundant 'int err;' declaration noticed by Christopher
James Halse Rogers. This was supposed to be in v2, but I missed it.

Subject: [PATCH 04/11] glx: Add tracking for GLX_ARB_create_context and GLX_ARB_create_context_profile
The formatting of the extension data table was mangled by indent.
This patch also undoes that and adds approripate control comments so
that indent won't do it again.
