This is basically half of Keith's draw/flush patch.
The stage->point/line/tri() functions are now self-validating, the validator
functions are installed by the flush() function.
There were excessive calls to validate_pipeline(), however. This was caused
by draw_prim_queue_flush() keeping a local 'first' variable that always pointed
to the validate functions. Replaced 'first' with 'draw->pipeline.first'.
Performance in gears is up just slightly with this patch.

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.
|
|
Something similar will return when geometry shaders are added, but for now
this interface is not required.
|
|
Directly use struct pipe_buffer_handle for storage and struct pipe_surface for
(un)mapping.
|
|
Use FREE, MALLOC, CALLOC, GETENV wrappers.
Silence compiler warnings.
Add proper copyrights.

This reverts commit 11ce6244a79106c592364b30434b6ddade3fd6bb.

Also, quite a bit of re-org of the tile caches and surface mapping/unmapping.
Leave surfaces mapped between primitives now.

|
They're now totally independent of the actual shaders.
Also, implemented in terms of pipe_buffer_handles/objects.
|
|
Creates a new pipe driver that feeds commands to either a hardware or
software pipe depending on fallback state.
Untested concept checkpoint. At this point it compiles.

We weren't mapping all the needed vertex array buffers.
Move array state that was temporarily in draw_context to softpipe_context.
Remove a bunch of dead code.

Move code duplicated between draw_vb.c and sp_draw_arrays.c into draw_prim.c
draw_vb.c will eventually go away, but this seems like a good step anyway.

Also includes:
Temporary stand-in for vertex program execution.
draw_prim() code
post-transform vertex cache
