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().

move it to pipe/internal/p_winsys_screen.h and start converting
the state trackers to the screen usage

This commit is mostly just a cosmetic change that cleans-up the interfaces,
replacing pipe_winsys::surface_* calls by
/**
* Allocate storage for a display target surface.
*
* Often surfaces which are meant to be blitted to the front screen (i.e.,
* display targets) must be allocated with special characteristics, memory
* pools, or obtained directly from the windowing system.
*
* This callback is invoked by the pipe_screenwhen creating a texture marked
* with the PIPE_TEXTURE_USAGE_DISPLAY_TARGET flag to get the underlying
* buffer storage.

Most drivers were updated but not all were tested. Use the softpipe pipe
driver and the xlib winsys changes as a reference when fixing other drivers.

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

Also, rename p_tile.[ch] to u_tile.[ch]

Checkpoint commit. Most required code is in place, and compiles, but
totally untested.
