For cogl 2.0 we don't want to have a default context. In the meantime
we can simply assume that calling cogl_context_new() implicitly
sets that context as the default context before returning.

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.

we've got into a bit of a mess with how we name platform specific
symbols and files, so this is a first pass at trying to tidy that up.
All platform specific symbols should be named like
cogl_<platform>_symbol_name and similarly files should be named like
cogl-<platform>-filename.c
This patch tackles the X11 specific renderer/display APIs as a start.

This adds Xlib and Win32 typesafe replacements for
cogl_renderer_handle_native_event, cogl_renderer_add_native_filter,
cogl_renderer_remove_native_filter. The old functions are kept as an
implementation detail so we can share code.

Based on the Cogl example we had on wiki.clutter-project.org this shows
how to use the primitive API to draw a simple spinning crate.

This update the x11-foreign test so that it checks for events on its X
display and forwards them on to Cogl. It will now also quit if any key
of button is pressed.
The x11-foreign example directly uses the X11 API at it seems that more
recent versions of binutils complain if we don't directly link the test
with libX11 as opposed to relying on indirect linkage via cogl.
This adds an example cogl compositor to test the
_cogl_wayland_texture_2d_new_from_buffer API. The compositor emulates 4
output displays but doesn't support input since Cogl doesn't deal with
input. It's quite a minimal example of what it takes to write a wayland
compositor so could be interesting to anyone learning about wayland.
Actually calling cogl_set_default_context isn't required because
cogl_context_new implicitly sets the new context to be the default
context. Since we want to eventually get rid of the concept of a default
context we'd rather not pollute the example with the concept.
This extends cogl_onscreen_x11_set_foreign_xid to take a callback to a
function that details the event mask the Cogl requires the application
to select on foreign windows. This is required because Cogl, for
example, needs to track size changes of a window and may also in the
future want other notifications such as map/unmap.
Most applications wont need to use the foreign xwindow apis, but those
that do are required to pass a valid callback and update the event mask
of their window according to Cogl's requirements.
This adds Cogl API to show and hide onscreen framebuffers. We don't want
to go too far down the road of abstracting window system APIs with Cogl
since that would be out of its scope but the previous idea that we would
automatically map framebuffers on allocation except for those made from
foreign windows wasn't good enough. The problem is that we don't want to
make Clutter always create stages from foreign windows but with the
automatic map semantics then Clutter doesn't get an opportunity to
select for all the events it requires before mapping. This meant that we
wouldn't be delivered a mouse enter event for windows mapped underneath
the cursor which would break Clutters handling of button press events.
This adds a simple standalone Cogl application that can be used to
smoke test a standalone build of Cogl without Clutter.
This also adds an x11-foreign app that shows how a toolkit can ask Cogl
to draw to an X Window that it owns instead of Cogl being responsible
for automatically creating and mapping an X Window for CoglOnscreen.
