This adds cogl_texture_2d_sliced_new_from_bitmap/data/file apis in
preparation for removing the cogl_texture_new_from_bitmap/file apis that
are considered a bit too magic, but we don't want to loose the
convenience they have.

This exposes the CoglAtlasTexture api, making the following public:
cogl_atlas_texture_new_with_size
cogl_atlas_texture_new_from_file
cogl_atlas_texture_new_from_data
cogl_atlas_texture_new_from_bitmap
The plan is to remove auto-texture apis like cogl_texture_new_from_file
since they are a bit too magic, but that means we need an explicit way
for users to allocate texture that will go in the atlas.
Although the _new_from_file() api is arguably redundant since you can
use _bitmap_new_from_file() followed by _atlas_texture_new_from_bitmap()
we don't want to loose any of the convenience that
cogl_texture_new_from_file() had.

This removes the gl centric _cogl_texture_prepare_for_upload api from
cogl-texture.c and instead adds a _cogl_bitmap_convert_for_upload() api
which everything now uses instead. GL specific code that needed the gl
internal/format/type enums returned by _cogl_texture_prepare_for_upload
now use ->pixel_format_to_gl directly.
Since there was a special case optimization in
cogl_texture_new_from_file that aimed to avoid copying the temporary
bitmap that's created for the given file and allow conversions to
happen in-place the new _cogl_bitmap_convert_for_upload() api supports
converting in place depending on a 'can_convert_in_place' argument.
This ability to convert bitmaps in-place has been integrated across the
different components as appropriate.
In updating cogl-texture-2d-sliced.c this was able to remove a number of
other GL specific parts to how spans are setup.

Previously when trying the three different texture types to create an
automagic texture it would handle the out-of-memory error specially
and bypass trying the remaining texture types. Presumably the idea is
that out-of-memory is a serious error and it can't be recovered from.
However, in the case of atlas textures, this error will be thrown if
the texture is too large to fit into an atlas. In that case it makes
sense to try another texture type so that it can fallback to using a
sliced texture. I think conceptually each different texture type will
have different memory requirements so it seems reasonable to try the
others if there is not enough memory for one of them.
This was causing cogl_texture_new_from_data to break when loading very
large textures because it wouldn't end up slicing them.

Consistent with how we lazily allocate framebuffers this patch allows us
to instantiate textures but still specify constraints and requirements
before allocating storage so that we can be sure to allocate the most
appropriate/efficient storage.
This adds a cogl_texture_allocate() function that is analogous to
cogl_framebuffer_allocate() which can optionally be called to explicitly
allocate storage and catch any errors. If this function isn't used
explicitly then Cogl will implicitly ensure textures are allocated
before the storage is needed.
It is generally recommended to rely on lazy storage allocation or at
least perform explicit allocation as late as possible so Cogl can be
fully informed about the best way to allocate storage.

Note: This reverts the cogl_texture_rectangle_new_with_size API change
that dropped the CoglError argument and keeps the semantics of
allocating the texture immediately. This is because Mutter currently
uses this API so we will probably look at updating this later once
we have a corresponding Mutter patch prepared. The other API changes
were kept since they only affected experimental api.
‘Propagate’ was misspelled as ‘propogate’.

This splits out the very high level texture constructors that may
internally construct one of several types of lower level texture due to
various constraints.
This also updates the prototypes for these constructors to take an
explicit context pointer and return a CoglError consistent with other
texture constructors.
