The core reference counting code is centralized in p_refcnt.h.
This has some consequences related to struct pipe_buffer:
* The screen member of struct pipe_buffer must be initialized, or
pipe_buffer_reference() will crash trying to destroy a buffer with reference
count 0. u_simple_screen takes care of this, but I may have missed some of
the drivers not using it.
* Except for rare exceptions deep in winsys code, buffers must always be
allocated via pipe_buffer_create() or via screen->*buffer_create() rather
than via winsys->*buffer_create().

Saves code, and will simplify future interface changes.

reuse the size of the actual buffer

We want to use the pipe_buffer_* inlines everywhere, but a pipe context
is not always available nor is it needed.

This allows us to remove most of the direct references to winsys in the state tracker.

If only glUniform is called between two renderings, the const buffers weren't
getting updated. Need to set the _NEW_PROGRAM flag in st_upload_constants()
as that's the dirty flag set by glUniform.
Fixes glean tapi2 test.

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.

The properties of a buffer represented by struct pipe_buffer_handle are now
basically constant over its lifetime. The state tracker gets to deal with any
more complex buffer semantics it may need to provide.

Winsys driver needs some hints in order to allocate the appropriate kind of
memory for the buffer.
