Since cogl-pipeline.c has become very unwieldy this make a start at
trying to shape this code back into a manageable state. This patche
moves all the API relating to core pipeline state into
cogl-pipeline-state.c. This doesn't move code relating to layer state
out nor does it move any of the code supporting the core design
of CoglPipeline itself.
This change alone factors out 2k lines of code from cogl-pipeline.c
which is obviously a good start. The next step will be to factor
out the layer state and then probably look at breaking all of this
state code down into state-groups.

Add a method on the renderer to know how many texture image units are
accessible from fragment shaders.

Similar to the widely used gluLookAt API, this adds a CoglMatrix utility
for setting up a view transform in terms of positioning a camera/eye
position that points to a given object position aligned to a given
world-up vector.

This makes cogl_framebuffer_clear and cogl_framebuffer_clear4f public as
experimental API. Since these functions take explicit framebuffer
pointers you don't need to push/pop a framebuffer just to clear it. Also
these functions are implicitly tied to a specific CoglContext via the
framebuffer pointer unlike cogl_clear.

This adds a function to query what CoglContext a given framebuffer
belongs too. This can be useful if you pass framebuffer pointers around
and at some point you want to create another framebuffer as part of the
same context as a given framebuffer without assuming there is a single
default context.

This adds CoglPipeline and CoglFramebuffer support for setting a color
mask which is a bit mask defining which color channels should be written
to the current framebuffer.
The final color mask is the intersection of the framebuffer color mask
and the pipeline color mask. The framebuffer mask affects all rendering
to the framebuffer while the pipeline masks can be used to affect
individual primitives.

The experimental 2.0 reference manual was setup with DOC_MODULE name of
"cogl" which conflicted with the 1.x API manual. This meant that when
running make install for both the reference manuals all the html files
would end up bundled together in the same location. The 2.0 API
reference now has a DOC_MODULE name of "cogl-2.0-experimental" the
corresponding -sections.txt and -docs.xml.in files have also been
renamed to match this.

There were several CoglOnscreen functions named like:
cogl_onscreen_<platform>_blah instead of cogl_<platform>_onscreen_blah
so this patch updates those to be consistent with other platform
specific apis we have in cogl.

This fixes the 2.0 reference manual Makefile to not ignore
cogl-context.h; it also adds cogl_context_new to cogl-sections.txt and
removes cogl_begin/end_gl. (For using raw GL with Cogl 2.0 the plan was
to add some API for creating additional GL contexts via some Cogl API
and a way to push/pop those contexts.)

we've got into a bit of a mess with how we name platform specific

All platform specific symbols should be named like

cogl-<platform>-filename.c

Since gtk-doc is an optional dependency for Cogl then we need to special
case how EXTRA_DIST is initialized. It shouldn't be set when using
gtk-doc since gtk-doc.make expects to initialize EXTRA_DIST. If we
aren't using gtk-doc then it should be initialized to an empty value
instead of including gtk-doc.make so that the later lines that append
various extra png files to EXTRA_DIST won't fail.
This explicitly renames the cogl-2.0 reference manual to
cogl-2.0-experimental and renames the cogl-2.0 pkg-config file to
cogl-2.0-experimental.pc. Hopefully this should avoid
miss-understandings.
