This adds cogl_framebuffer_ apis for drawing attributes and primitives
that replace corresponding apis that depend on the default CoglContext.
This is part of the on going effort to adapt the Cogl api so it no
longer depends on a global context variable.
All the new drawing functions also take an explicit pipeline argument
since we are also aiming to avoid being a stateful api like Cairo and
OpenGL. Being stateless makes it easier for orthogonal components to
share access to the GPU. Being stateless should also minimize any
impedance miss-match for those wanting to build higher level stateless
apis on top of Cogl.
Note: none of the legacy, global state options such as
cogl_set_depth_test_enabled(), cogl_set_backface_culling_enabled() or
cogl_program_use() are supported by these new drawing apis and if set
will simply be silently ignored.

This adds two new functions:
void
cogl_poll_get_info (CoglContext *context,
CoglPollFD **poll_fds,
int *n_poll_fds,
gint64 *timeout);
void
cogl_poll_dispatch (CoglContext *context,
const CoglPollFD *poll_fds,
int n_poll_fds);
The application is expected to call the first function whenever it is
about to block to go idle, and the second function whenever it comes
out of idle. This gives Cogl winsys's the ability poll file
descriptors for events. For example when handing swap complete
notifications, it can report that it needs to block on a file
descriptor.
The two functions are backed by winsys virtual functions. There are
currently no implementations. The default handler for get_info just
reports no file descriptors and an infinite timeout.

This adds a documentation section for CoglSnippet which gives an
overview of how to use them. It also fixes some syntax errors in the
existing documentation and adds the missing pipeline functions for
adding snippets to the documentation sections file.

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.
