181b875a3d xlib: Internally retrieve XEvents
Previously we relied on the application to send all X events through
Cogl using cogl_xlib_renderer_handle_event. This breaks the
abstraction that an application shouldn't need to know what winsys
Cogl is using. Now that we have main loop integreation in Cogl, the
Xlib-based winsys's can report that Cogl needs to block on the file
descriptor of the X connection and it can manually handle the
events.

The event retrieval can be disabled by an application if it calls the
new cogl_xlib_renderer_set_event_retrieval_enabled() function. The
event retrieval will also automatically be disabled if the application
sets a foreign display.

616d27f169 cogl-texture-2d: Fix checking for the EGL winsys
CoglTexture2D had an assert to verify that the EGL winsys was being
used. This doesn't make any sense any more because the EGL winsys
can't be used directly but instead it is just a base winsys for the
platform winsys's. To fix this this patch adds a set of 'criteria'
flags to each winsys, one of which is 'uses EGL'. CoglTexture2D can
use this to determine if the winsys is supported.

Eventually we might want to expose these flags publically so that an
application can select a winsys based on certain conditions. For
example, an application may need a winsys that uses X or EGL but
doesn't care exactly which one it is.

ff5bfc4a86 Rename the EGL_X11 winsys to EGL_XLIB
Eventually we might want to have an XCB-based EGL winsys. We already
have xlib-specific API in CoglRenderer (eg, to set a foreign display)
so the application needs to be able to specifically select between XCB
and XLIB.

This also removes the POWERVR part while renaming
COGL_HAS_EGL_PLATFORM_POWERVR_X11_SUPPORT to
COGL_HAS_EGL_PLATFORM_XLIB_SUPPORT because the winsys is equally
applicable to Mesa.

613a3390da winsys: Move X11/Xlib-specific code out of the EGL winsys
All of the X11/Xlib-specific code now lives in the EGL_X11 winsys.

a1e1527b69 Add a separate winsys vtable for each EGL platform
Instead of just having an "EGL" renderer, there is now a separate
winsys for each platform. Currently they just directly copy the vtable
for the EGL platform so it is still only possible to have one EGL
platform compiled into Cogl. However the intention is that the
winsys-specific code for each platform will be moved into override
functions in the corresponding platform winsys.
