Subject: [PATCH 2/5] cogl/gl-framebuffer: Fix inverted test in
 ensure_bits_initialized()

Cogl's feature COGL_PRIVATE_FEATURE_QUERY_FRAMEBUFFER_BITS is required
to use the GL_FRAMEBUFFER_ATTACHMENT_* queries.

Unfortunately, the test for the availability of the private feature is
actually inverted in ensure_bits_initialized() which causes that whole
portion of code to be ignored, falling back to the glGetIntegerv()
method which isn't supported in core profiles.

As Mesa has recently started to be more strict about these, this causes
the CI tests to fail in mutter.

Subject: [PATCH 3/5] cogl/gl-framebuffer: Match testing features

The function ensure_bits_initialized() in cogl-gl-framebuffer-fbo.c
checks for COGL_PRIVATE_FEATURE_QUERY_FRAMEBUFFER_BITS whereas the same
in cogl-gl-framebuffer-back.c simply checks for the driver being
COGL_DRIVER_GL3.

Change the later to use the COGL_PRIVATE_FEATURE_QUERY_FRAMEBUFFER_BITS
flag as well.

Subject: [PATCH 4/5] cogl/gl-framebuffer: Fail without QUERY_FRAMEBUFFER_BITS

glGetIntegerv() with GL_RED_BITS/GL_GREEN_BITS/GL_BLUE_BITS/etc. is not
supported with the GL core context, so there is no point in falling back
to that without supporting COGL_PRIVATE_FEATURE_QUERY_FRAMEBUFFER_BITS,
as this will cause an GL error.
