Instead, a new pipe_transfer object has to be created and mapped for
transferring data between the CPU and a texture. This gives the driver more
flexibility for textures in address spaces that aren't CPU accessible.
This is a first pass; softpipe/xlib builds and runs glxgears, but it only shows
a black window. Looks like something's off related to the Z buffer, so the
depth test always fails.

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.
*/
struct pipe_buffer *(*surface_buffer_create)(struct pipe_winsys *ws,
unsigned width, unsigned height,
enum pipe_format format,
unsigned usage,
unsigned *stride);
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.

The chars-per-pixel concept falls apart with compressed and yuv images,
where more than one pixel are coded in a single data block.

When a surface is created with GPU_WRITE that really means "GPU render"
and that can involve reads (blending). Set surface usage to
PIPE_BUFFER_USAGE_CPU_READ + WRITE. Fixes progs/demos/lodbias demo.
Also, mark texture as 'modified' when mapped for writing so that the tile
cache can know when to freshen a cached tile. Fixes glTexSubImage2D().

For many envirionments it's necessary to allocate display targets
in a window-system friendly manner. Add facilities so that a driver
can tell if a texture is likely to be used to generate a display surface
and if use special allocation paths if necessary.
Hook up softpipe to call into the winsys->surface_alloc_storage()
routine in this case, though we probably want to change that interface
slightly also.

Called whenever texture data is changed (glTexImage, glTexSubImage,
glCopyTexSubImage, etc).

This is in a separate commit to ensure renames are properly preserved.
