24fde77c62 buffer: add format param to get_data_ptr 
Allow wlr_buffer_impl.get_data_ptr to return a format.

This allows the Pixman renderer to not care about get_dmabuf/get_shm,
and only care about get_data_ptr. This will also help with [1], because
client wl_shm buffers can't implement get_shm.

c6b009ef85 render: introduce shared memory allocator 
It allocates in local main memory via shm_open, and provides a FD
to allow sharing with other processes.

This is suitable for software rendering under the Wayland and X11
backends.
