gallium: rename pipe_buffer_handle to pipe_buffer, rework pipebuffer/ code
Provide an actual definition of the pipe_buffer struct, containing the parameters used to create the buffer, and its refcount. Shift refcounting buffers out of the winsys interface, similar to surfaces & textures. Rework pipebuffer/ to reflect the fact these changes, and also Michel's reworking of the buffer interface.
