When splitting out the CoglPath api we saw that we would be left with
inconsistent drawing apis if the drawing apis in core Cogl were lumped
into the cogl_framebuffer_ api considering other Cogl sub-libraries or
that others will want to create higher level drawing apis outside of
Cogl but can't use the same namespace.
So that we can aim for a more consistent style this adds a
cogl_primitive_draw() api, comparable to cogl_path_fill() or
cogl_pango_show_layout() that's intended to replace
cogl_framebuffer_draw_primitive()
Note: the attribute and rectangle drawing apis are still in the
cogl_framebuffer_ namespace and this might potentially change but in
these cases there is no single object representing the thing being drawn
so it seems a more reasonable they they live in the framebuffer
namespace for now.
Note: the cogl_framebuffer_draw_primitive() api isn't removed by this
patch so it can more conveniently be cherry picked to the 1.16 branch so
we can mark it deprecated for a short while. Even though it's marked as
experimental api we know that there are people using the api so we'd
like to give them a chance to switch to the new api.

The plan is to remove the cogl-auto-texture apis since they hide a bit
too much from developers but currently the conformance tests depend on
these apis in numerous places.
For the conformance tests it makes some sense to continue using high
level texture apis similar to the auto-texture apis since we may want
to make broad variations to how textures are allocated as part of the
testing running if that might help exercise more code paths.
This patch copies much of the auto-texture functionality into some
slightly more special purpose utilities in test-utils.c/h. Minor changes
include being constrained to the public Cogl api and they also don't
let you catch CoglErrors and just assume they should abort on error.

bitmap that's created for the given file and allow conversions to

Instead of queuing the frame sync event immediately after a swap, the
Wayland winsys now installs a frame callback and queues the event when
Wayland reports that the frame is complete. It also reports the
COGL_FRAME_EVENT_COMPLETE event at the same time because there is no
more information we can give.
This patch is a bit of a divergence from how the events are handled in
the GLX winsys. Instead of installing its own idle function, the
_cogl_onscreen_queue_event() function has now been made non-static so
that it can be used by the Wayland winsys. The frame callback now just
queues an event using that. The pending_frame_infos queue on the
CoglOnscreen isn't used and instead the CoglFrameInfo is immediately
popped off the queue so that it can be stored as part of the closure
data when the frame callback is set up. That way it would use the
right frame info even if somehow the Wayland callbacks were invoked in
the wrong order and the code is a bit simpler.

Previously if the Wayland socket gets closed then Cogl would ignore
the error when dispatching events which meant the socket would be
constantly ready for reading, the main loop would never go idle and it
would sit at 100% CPU. When Wayland encounters an error it will
actually close the socket which means if something else opened another
file then we might even end up polling on a completely unrelated FD.
This patch makes it remove the FD from the main loop as soon as it
hits an error so that it will at least avoid breaking the main loop.
However I think most applications would probably want to abort in this
case so we might also want to add a way to inform the application of
this or even just abort directly.
The cogl_poll_* functions have been changed so that they can cope if
the pending and dispatch callbacks remove their own FD while they are
invoked.

Previously Cogl would only call wl_display_flush after doing a swap
buffers on the onscreen because that is the only place where Cogl
itself would end up queueing requests. However since commit
323fe188748 Cogl takes control of calling wl_display_dispatch as well
which effectively makes it very difficult for the application to
handle the Wayland event queue itself. Therefore it needs to rely on
Cogl to do it which means that other parts of the application may also
queue requests that need to be flushed.
This patch tries to copy the display fd handling of window.c in the
Weston example clients. wl_display_flush will always be called in
prepare function for the fd which means it will always be called
before going idle. If flushing the display causes the socket buffer to
become full, it will additionally poll for write on the FD to try
flushing again when it becomes empty.
We also need to call wl_display_dispatch_pending in the prepare
because apparently calling eglSwapBuffers can cause it to read data
from the FD to receive events for a different queue. In that case
there will be events that need to be handled but the FD will no longer
be ready for reading so we won't wake up the main loop any other way.
