[Mesa-dev] [PATCH v4 0/7] Support Desktop GL Core contexts

[Jordan Justen]

These patches introduce a MESA API type of API_OPENGL_CORE,
which will not support legacy/non-CORE features. The intended
usage will be with contexts for Desktop GL >= 3.1.

The series will currently cause legacy/non-CORE functions
to generate a GL_INVALID_OPERATION error if an API_OPENGL_CORE
context is created.

Since MESA currently cannot create a context of API_OPENGL_CORE,
this series should not actually change the behaviour of MESA.
Future changesets will add the ability to create API_OPENGL_CORE
contexts.

This series also does not address deprecated enums usage or
extensions for CORE contexts.

v4:
 * In v3, I accidentally combined patches 6 & 7. In v4, I
   re-separate them.

v3:
 * IS_CTX_DESKTOP_GL => _mesa_is_desktop_gl
 * IS_CTX_GLES => _mesa_is_gles
 * Add a few comments to point out GL Legacy as
   distinct from GL Core

v2:
 * Decompose patches further
 * Drop DRI changes
 * Drop state_tracker changes
 * Drop MESA_GL_API_OVERRIDE variable

v1:
 * Add CORE API type
 * Alter code paths to generate errors for legacy functions
 * Add MESA_GL_API_OVERRIDE variable
