[PATCH 0/5] Add generic buffer formats

This series adds generic buffer formats (at the wl_buffer level) and YUV formats
in particular. I believe this is generally useful because even for SHM buffers,
we could also represent YUV contents in there. e.g. gstreamer sink.
Patch 1 adds the generic buffer types. Those are the most commonly used formats
only. Besides, I also dropped YUV/YVU variants as YVU is YUV with different layout.
Talking of which, Patch 2 adds some layout infrastructure. If you already have
an allocated SHM buffer around, it's theoritically possible to attach a particular
layout to it. However, I didn't want to expose that because if the user allocates
a YUV buffer, it will tend to have the same layout for the lifetime of the object.
And, if the layout needs to be changed, allocating a new buffer should not be that
Since I added the layout right into the wl_buffer base object, Patch 3 bumps the
version of its interface.
Patch 4 fills in layout information for SHM buffers.
Patch 5 adds some helpers to extract a sensible layout even if the buffer was
implemented for a former interface.
Gwenole Beauchesne (5):
buffer: add generic buffer formats.
buffer: add layout information.
buffer: bump version.
shm: fill in base buffer layout.
buffer: add helper accessors.
