Cogl always needs to have the context bound to something so that it
can freely create resources such as textures even if there is no
current window. When the currently bound SDLWindow is destroyed, SDL
apparently explicitly unbinds the GL context. If something then later
for example tries to create a texture Cogl would start getting GL
errors and fail. To fix this the SDL winsys now just binds the dummy
window before deiniting the currently bound onscreen.

We have found several times now when writing code using Cogl that it
would really help if Cogl's matrix stack api was public as a utility
api. In Rig for example we want to avoid redundant arithmetic when
deriving the matrices of entities used to render and we aren't able
to simply use the framebuffer's matrix stack to achieve this. Also when
implementing cairo-cogl we found that it would be really useful if we
could have a matrix stack utility api.

At times there can be huge numbers of CoglMatrixEntry structures
allocated if they are being used to track the transform of many drawing
commands or objects in a scenegraph. Therefore the size of a
CoglMatrixEntry should be kept as small as possible both to help reduce
the memory usage of applications but also to improve cache usage since
matrix stack manipulations are performance critical at times.
This reduces the size of CoglMatrixEntry structures for non-debug builds
by removing the composite_gets counter used to sanity check how often
the transform for an entry is resolved.

When unrefing a CoglMatrixEntry we walk up the ancestry unrefing and
freeing entries until we find an entry that doesn't need to be freed.
The problem fixed by this patch was that we didn't dereference the
parent member of each entry until after the entry was freed and so there
was the potential for reading a junk parent pointer back.

The _cogl_propagate_error() function takes ownership of the incoming
error pointer so there's no need to allocate a new error when passing
it on. The errors can potentially be passed up from a number of layers
so it seems worthwhile to avoid the allocation.
The _cogl_propagate_gerror() function was previously using
_cogl_propagate_error(). Presumably this would not have worked because
that function would try to free the error from glib using
cogl_error_free but that would use the wrong free function and thus
the wrong slice allocator. The GError propagating function is only
used when gdk-pixbuf is enabled which now requires glib support anyway
so we can just avoid defining the function when compiling without
glib.

This allows apps to catch out-of-memory errors when allocating textures.
Textures can be pretty huge at times and so it's quite possible for an
application to try and allocate more memory than is available. It's also
very possible that the application can take some action in response to
reduce memory pressure (such as freeing up texture caches perhaps) so
we shouldn't just automatically abort like we do for trivial heap
allocations.
These public functions now take a CoglError argument so applications can
catch out of memory errors:
cogl_buffer_map
cogl_buffer_map_range
cogl_buffer_set_data
cogl_framebuffer_read_pixels_into_bitmap
cogl_pixel_buffer_new
cogl_texture_new_from_data
cogl_texture_new_from_bitmap
Note: we've been quite conservative with how many apis we let throw OOM
CoglErrors since we don't really want to put a burdon on developers to
be checking for errors with every cogl api call. So long as there is
some lower level api for apps to use that let them catch OOM errors
for everything necessary that's enough and we don't have to make more
convenient apis more awkward to use.
The main focus is on bitmaps and texture allocations since they
can be particularly large and prone to failing.
A new cogl_attribute_buffer_new_with_size() function has been added in
case developers need to catch OOM errors when allocating attribute buffers
whereby they can first use _buffer_new_with_size() (which doesn't take a
CoglError) followed by cogl_buffer_set_data() which will lazily allocate
the buffer storage and report OOM errors.

Note: since we can't break the API for Cogl 1.x then actually the main
purpose of cherry picking this patch is to keep in-line with changes
on the master branch so that we can easily cherry-pick patches.
All the api changes relating stable apis released on the 1.12 branch
have been reverted as part of cherry-picking this patch so this most
just applies all the internal plumbing changes that enable us to
correctly propagate OOM errors.
constant attributes don't have a corresponding buffer so
_cogl_attribute_free shouldn't try to unref it. Also, for good measure,
in the case of constant attributes we should call
_cogl_boxed_value_destroy() (although currently we know there is no
dynamic data associated with the boxed values).
