This makes some changes to _cogl_bitmap_gl_bind to be more paranoid
about bad access arguments and make sure we don't mark a bitmap as bound
if there was an error in _cogl_buffer_gl_bind.
We now validate the access argument upfront to check that one of _READ
or _WRITE access has been requested. In the case that cogl is built
without debug support then we will still detect a bad access argument
later and now explicitly return before marking the bitmap as bound, just
in case the g_assert_not_reach has been somehow disabled. Finally we
defer setting bitmap->bound = TRUE until after we have check for any
error with _cogl_bitmap_gl_bind.

Some public headers were added, so these need to be "installed" as well.
Also clean up the preprocessor definitions as they were meant to be
in cogl/cogl-defines.h.
Previously the sampler uniform declarations such as cogl_sampler0 were
generated by walking the list of layers in the shader state. This had
two problems. Firstly it would only generate the declarations for
layers that have been referenced. If a layer has a combine mode of
replace then the samplers from previous layers couldn't be used by
custom snippets. Secondly it meant that the samplers couldn't be
referenced by functions in the declarations sections because the
samplers are declared too late.
This patch fixes it to generate the layer declarations in the backend
start function using all of the layers on the pipeline instead. In
addition it adds the sampler declarations to the vertex shader as they
were previously missing.

This adds hook points to add global function and variable declarations
to either the fragment or vertex shader. The declarations can then be
used by subsequent snippets. Only the ‘declarations’ string of the
snippet is used and the code is directly put in the global scope near
the top of the shader.
The reason this is necessary rather than just adding a normal snippet
with the declarations is that for the other hooks Cogl assumes that
the snippets are independent of each other. That means if a snippet
has a replace string then it will assume that it doesn't even need to
generate the code for earlier hooks which means the global
declarations would be lost.

glMapBufferRange is documented to fail with GL_INVALID_OPERATION if
GL_MAP_INVALIDATE_BUFFER_BIT is set as well as GL_MAP_READ_BIT. I
guess this makes sense when only read access is requested because
there would be no point in reading back uninitialised data. However,
Clutter requests read/write access with the discard hint when
rendering to a CoglBitmap with Cairo. The data is new so the discard
hint makes sense but it also needs read access so that it can read
back the data it just wrote for blending.
This patch works around the GL restriction by skipping the discard
hints if read access is requested. If the buffer discard hint is set
along with read access it will recreate the buffer store as an
alternative way to discard the buffer as it does in the case where the
GL_ARB_map_buffer_range extension is not supported.

It seems like it would be quite a reasonable design for an application
to immediately paint the buffer and call swap_buffers within the
handler for the sync event. This previously wouldn't work.
When using the GLX winsys if swap_region is called then it immediately
tries to set the pending notification flag. However if this is called
from the event callback then when the callback is complete it will
clear the flag again and the pending notification will be lost. This
patch just makes it clear the pending flag before invoking the
callback so that it can be safely queued again.
With any winsys that doesn't directly handle the sync event
notification it would almost work except that it was iterating the
live list of pending events. If the callback causes another event to
be added to this list by issuing a buffer swap then the iteration
would never complete and cogl_poll_dispatch would never return. This
patch just makes it steal the list before iterating so that any
additions will be dispatched by a later call to cogl_poll_dispatch
instead.

The two SDL examples now throttle their rendering to the
COGL_FRAME_EVENT_SYNC event. Previously the examples would redraw
whenever a mouse motion event is received but now they additionally
wait for the sync event which means that if another mouse event comes
immediately after rendering the last frame it theoretically could
avoid blocking waiting for the last frame to complete. In practice
however the SDL winsys doesn't support swap events so it will get the
sync event immediately anyway, but it's nice to have the code as an
example and a test.

without the outer main loop which I think makes it a bit easier to
