[Mesa-dev] [PATCH 02/18] mesa: Add {OES, EXT}_tessellation_shader to the extensions table.

[Kenneth Graunke]

Also update _mesa_has_tessellation to know about the new extensions.

For now, these are dummy_false, to avoid turning on the extension
until everything's in place.  Eventually, we'll move them over to
the "ARB_tessellation_shader" bit so that any drivers supporting
both the desktop extension and ES 3.1 get the feature.
