Add framebuffer methods cogl_framebuffer_[gs]et_depth_write_enabled()
and backend bits to pass the state on to glDepthMask().
This allows us to enable or disable depth writing per-framebuffer, which
if disabled saves us some work in glClear(). When rendering, the flag
is combined with the pipeline's depth writing flag using a logical AND.
Depth writing is enabled by default.

Depending on what version of Mesa you have then eglQueryWaylandBuffer
may take a wl_buffer or wl_resource argument and the EGL header will
only forward declare the corresponding type.
The use of wl_buffer has been deprecated and so internally we assume
that eglQueryWaylandBuffer takes a wl_resource but for compatibility we
forward declare wl_resource in case we are building with EGL headers
that still use wl_buffer.

cogl_is_atlas_texture is supposed to be exported from the DLL/.so, so
update the cogl.symbols file to ensure this.

This makes cogl_framebuffer_set_color_mask immediately bail out if the
given mask equals the framebuffer's current mask, since the cost of
flushing the journal and flushing the gl state will hugely outweigh the
cost of the check.

This updates the definition of _COGL_STATIC_ASSERT to just use
_Static_assert if available or be NOP if not. We no longer worry about
supporting static assertions with older compilers. This fixes some
verbose warnings that newer compilers were giving with the old typedef
based static assertion method.

When a pipeline is notified of a change we now make sure to notify all
progends of that change not just the progend directly associated with
that pipeline. A pipeline can have private state associated with it from
multiple progends because descendants will always try and cache state on
ancestors to maximize the chance that the state can later be re-used.
Descendants may be using different progends than the ancestors that they
cache state with.

This avoids including wayland-server.h in cogl-display-private.h which
avoid lots of compile time warnings that wl_buffer is deprecated. The
problem is that wl_buffer is also exposed in the client side headers and
isn't deprecated for clients. If we end up including the client and
server headers in the same compilation unit we can get conflicting
definitions.

This makes a start on clearly factoring the deprecated code of core Cogl
into a deprecated/ directory. Ideally we want to get to the point where
all code here can be re-worked in terms of the public 2.0 api so that it
can be kept indefinitely for cogl 1.x api compatibility without
cluttering the core code base itself. If we can do this then we can
avoid maintaining the Cogl 1.x branches in parallel with master which
would reduce the maintenance effort.
Commit 7b25c8f5ca mistakenly added a reference to a
COGL_GTYPE_DEFINE_CLASS() macro that does not yet exist so this patch
removes it.
