commit 188752158 changed cogl to stop needlessly creating its own
monitor output configuration when mutter would just soon overwrite
it anyway.
Unfortunately, that commit is causing a crash in some cases because
cogl will now create and later draw to a 0x0 egl surface until mutter
sets the monitor layout.
This commit changes cogl to avoid creating and using a surface, before
it knows how big of a surface to create.

If we get EACCES from drmPageFlip we're not going to get
a flip event and shouldn't wait for one.
This commit changes the EACCES path to silently ignore the
failed flip request and just clean up the fb.

ES3 provides glMapBufferRange as core, with the added bonus that it also
supports read mappings. Use this where possible.

GLES2 does not support passing READ to glMapBuffer; attempting to call
cogl_buffer_map for read on ES2 will bring it down with an assert. Make
sure COGL_DEBUG=journal doesn't do this when it's not possible.

On Wayland deinit() of an onscreen buffer is going to destroy the
associated native window of an EGLSurface. So we should destroy the
EGLSurface as well otherwise we might end up confusing the GL driver.
We also currently guard against setting a EGL_NO_SURFACE as current
EGLSurface, but this shouldn't be a problem if we have a surfaceless
context. So we allow surface destruction under that condition.

If the user switches VTs in the middle of a page flip, the
page flip operation may fail with EACCES. page flipping will
work next time the VT becomes active, so we shouldn't disable
page flipping in that case.

If cogl fails to open the drm device, initialize gbm, or open the
egl display, then it closes the drm fd, uninitializes gbm, closes the
display and then calls _cogl_winsys_renderer_disconnect which does
most of those things again, on the, now deinitialized, members.
This commit removes the explicit failure handling in renderer_connect and
defers cleanup to disconnect.

gbm confusingly has two different format types, and cogl
is using the wrong one in some of its calls to gbm_surface_create
This commit fixes the calls that are wrong.

glGetIntegerv (GL_DEPTH_BITS, ...) and friends are deprecated in GL3; we
have to use glGetFramebufferAttachmentParameteriv() instead, like we do
for offscreen framebuffers.

We want to be able to retrieve the XVisualInfo used when creating the
GL context under GLX and EGL-X11, so that we can use the visual before
we have an onscreen frame buffer.
Initialize variables; GCC does not always catch all cases where the
variables are used after being initialized, especially when it comes to
out parameters.
