The WL_bind_wayland_display spec says that EGL images should be created
using EGL_WAYLAND_BUFFER_WL as the target and a NULL context. Mesa
seems to be lenient and accept any context, however some other stacks
aren't so forgiving and fail if anything apart from EGL_NO_CONTEXT is
used.

Mutter (and libmutter users) are the only users of this version of
cogl, and will more or less only use the cogl-1.0, cogl-2.0 and cogl

it is error prone and confusing. Lets just remove the possibility of
having different versions of the same API.

CoglFrameInfo is a frame info container associated with a single

ClutterFrameInfo and adapts the stage windows and past onscreen frame

On Wayland deinit() of an onscreen buffer is going to destroy the

EGLSurface as well otherwise we might end up confusing the GL driver.

We can't just destroy and replace the EGL and gbm surfaces while
they are still in use i.e. while there is a pending flip. In fact, in
that case, we were calling gbm_surface_destroy() on a surface that
still had the front buffer locked and then, on the flip handler,
gbm_surface_release_buffer() for a buffer that didn't belong to the
new surface.
Instead, we still allocate new surfaces when requested but they only
replace the old ones on the next swap buffers when we're sure that the
previous flip has been handled and buffers properly released.
Currently the code queries the current msc then tries to approximate the
value of the next msc satisfing the modulus 2 for when to wait. This
introduces some instability as the msc may tick over during the
roundtrip leading to a 32ms wait instead of a 16ms wait. This happens
often enough to cause jerky animations, and affect gnome-shell-perf-tool.
A simpler solution is just use a single roundtrip by using WaitForMsc to
ask the driver to compute the next vblank itself.

The surfaceless context extension can be used to bind a context
without a surface. We can use this to avoid creating a dummy surface
when the CoglContext is first created. Otherwise we have to have the
dummy surface so that we can bind it before the first onscreen is
created.
The main awkward part of this patch is that theoretically according to
the GL and GLES spec if you first bind a context without a surface
then the default state for glDrawBuffers is GL_NONE instead of
GL_BACK. In practice Mesa doesn't seem to do this but we need to be
robust against a GL implementation that does. Therefore we track when
the CoglContext is first used with a CoglOnscreen and force the
glDrawBuffers state to be GL_BACK.
There is a further awkward part in that GLES2 doesn't actually have a
glDrawBuffers state but GLES3 does. GLES3 also defaults to GL_NONE in
this case so if GLES3 is available then we have to be sure to set the
state to GL_BACK. As far as I can tell that actually makes GLES3
incompatible with GLES2 because in theory if the application is not
aware of GLES3 then it should be able to assume the draw buffer is
always GL_BACK.

The previous implementation was dereferencing the sample pointer in
order to get the offset to subtract from the member pointer. The
resulting value is then only used to get a pointer to the member in
order to calculate the offset so it doesn't actually read from the
memory location and shouldn't cause any problems. However this is
probably technically invalid and could have undefined behaviour. It
looks like clang takes advantage of this undefined behaviour and
doesn't actually offset the pointer. It also generates a warning when
it does this.
This patch splits the _cogl_container_of macro into two
implementations. Previously the macro was always used in the list
iterator macros like this:
SomeType *sample = _cogl_container_of(list_node, sample, link)
Instead of doing that there is now a new macro called
_cogl_list_set_iterator which explicitly assigns to the sample pointer
with an initial value before assigning to it again with the real
offset. This redundant initialisation gets optimised out by compiler.
The second macro is still called _cogl_container_of but instead of
taking a sample pointer it just directly takes the type name. That way
it can use the standard offsetof macro.

Previously when a pipeline is added to the cache it would never be
removed. If the application is generating a lot of unique pipelines
this can end up effectively leaking a large number of resources
including the GL program objects. Arguably this isn't really a problem
because if the application is generating that many unique pipelines
then it is doing something wrong anyway. It also implies that it will
be recompiling shaders very often so the cache leaking will likely be
the least of the problems.
This patch makes it keep track of which pipelines in the cache are in
use. The cache now returns a struct representing the entry instead of
directly returning the pipeline. This entry contains a usage counter
which the pipeline backends can use to mark when there is a pipeline
alive that is using the cache entry. When the hash table decides that
it's a good time to prune some entries, it will make a list of all of
the pipelines that are not in use and then remove the least recently
used half of the pipelines. That way it is less likely to remove
pipelines that the application is actually regenerating often even if
they aren't in use all of the time.
When the cache is pruned the hash table makes a note of how small the
cache could be if it removed all of the unused pipelines. The hash
table starts pruning when there are more entries than twice this
minimum expected size. The idea is that if that case it hit then the
hash table is more than half full of useless pipelines so the
application is generating lots of redundant pipelines and it is a good
time to remove them.

test-path for example uses COGL_ENABLE_EXPERIMENTAL_2_0_API to access
the 2.0 CoglPath api but also uses deprecated framebuffer api such as
cogl_push/pop_framebuffer. Similarly clutter-backend.c builds with
COGL_ENABLE_EXPERIMENTAL_2_0_API and uses cogl_set_framebuffer().

This moves the framebuffer stack apis out of cogl-framebuffer.c into
cogl/deprecated/cogl-framebuffer-deprecated.c so cogl-framebuffer.c is
more in-line with the master branch to ease cherry picking patches.

This moves all of the automagic texture constructor prototypes from
cogl-texture.h into a new deprecated/cogl-auto-texture.h file. This also
moves cogl_texture_new_from_sub_texture() into
deprecated/cogl-auto-texture.c

Texture allocation is now consistently handled lazily such that the
internal format can now be controlled using
cogl_texture_set_components() and cogl_texture_set_premultiplied()
before allocating the texture with cogl_texture_allocate(). This means
that the internal_format arguments to texture constructors are now
redundant and since most of the texture constructors now can't ever fail
the error arguments are also redundant. This now means we no longer
use CoglPixelFormat in the public api for describing the internal format
of textures which had been bad solution originally due to how specific
CoglPixelFormat is which is missleading when we don't support such
explicit control over the internal format.

(cherry picked from commit 99a53c82e9ab0a1e5ee35941bf83dc334b1fbe87)
Note: there are numerous API changes for functions currently marked
as 'unstable' which we don't think are in use by anyone depending on
a stable 1.x api. Compared to the original patch though this avoids
changing the cogl_texture_rectangle_new_with_size() api which we know
is used by Mutter.
