Damien Lespiau 56dd71dba0 cogl: Introduce private feature flags and check for ARB_fp
The Cogl context has now a feature_flags_private enum that will allow us
to query and use OpenGL features without exposing them in the public
API.

The ARB_fragment_program extension is the first user of those flags.
Looking for this extension only happens in the gl driver as the gles
drivers will not expose them.

One can use _cogl_features_available_private() to check for the
availability of such private features.

While at it, reindent cogl-internal.h as described in CODING_STYLE.
