This also replaces use of CoglHandle with a CoglTexturePixmapX11 type
instead.
This patch also ensures the CoglTexturePixmapX11 constructor take an
explicit CoglContext pointer and can return a GError consistent with
other CoglTexture constructors.

This moves all the cogl_framebuffer_ apis relating to swap buffer
requests into the cogl_onscreen_ namespace since on CoglOnscreen
framebuffers have back buffers that can be swapped.

cogl_clear depends on the default CoglContext which we are trying to
steer the API away from requiring. cogl_framebuffer_clear4f is
explicitly passed a framebuffer pointer which is implicitly related to a
specific context.
This updates all the examples to use cogl_framebuffer_clear4f instead of
cogl_clear and removes any redundant CoglColor that was previously
passed to cogl_clear.

It used to be that cogl_framebuffer_allocate() had to be done explicitly
but we have since made Cogl lazily allocate framebuffers when they are
first used if they haven't already been explicitly allocated. Developers
only need to explicitly allocate framebuffers if they are planning to
gracefully handle any errors. In cases where the program will simply
abort due to an allocation error they can simply rely on implicit
allocation which will cause an abort on error.
This updates the examples to not explicitly allocate the framebuffers
since they all just abort on error anyway.

Xlib headers define many trivially named objects which can later cause
name collision problems when only cogl.h header is included in a program
or library. Xlib headers are now only included through including the
standalone header cogl-xlib.h.

This namespaces all of the examples and marks them for installation
if --enable-examples-install has been passed to ./configure. This
simplifies packaging the examples which can be quite convenient
for smoke testing Cogl on various platform.
