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.

Unfortunately both Mesa and Gallium use the same defines for memory
allocation (MALLOC, FREE, etc), and worse, some times memory is allocated
with one set and freed with the other set, causing the homegrown memory
debugger to trip on itself.
In the future mesa and gallium should use different names, but for now,
memory debugging on Windows will have to be carried with different tools..

May fail to parse otherwise.

When negating a src vector that's stored in a altivec register, need to put
negated value into a new register so we don't upset the original value.
This solves the dark colors in the mandelbrot GLSL demo.
Also, use new predicate functions to check if a TGSI temp is stored in
an altivec register.

Not really an error, as we only care for the lower 4 bits.

As advised by gcc -pedantic.

Unfinished, a big no-op for now.

Fixed size hash table. Collisions are handled by simply destroying the
previous entry.
It hasn't received much testing yet.

The following construction in util_surface_copy() in
gallium/auxiliary/util/u_rect.c, introduced in commit
d177c9ddda2c452cf7d6696d89cf4458ef986f98, incorrectly inverts
the Y coordinate in the last parameter to pipe_copy_rect().
/* If do_flip, invert src_y position and pass negative src stride
*/
pipe_copy_rect(dst_map,
&dst->block,
dst->stride,
dst_x, dst_y,
w, h,
src_map,
do_flip ? -(int) src->stride : src->stride,
src_x,
do_flip ? w - src_y : src_y);
The intention is to start at the last Y coordinate line and move
backwards, in the case of a flip; in that case, the correct
calculation is "src_y + h - 1", not "w - src_y".
This fixes a Gallium assertion failure in the conformance tests:
u_rect.c:65:pipe_copy_rect: Assertion `src_y >= 0' failed.
debug_get_bool_option: GALLIUM_ABORT_ON_ASSERT = TRUE
Trace/breakpoint trap

Remove the old/initial vbuf allocation in util_create_gen_mipmap().
We were allocating a small vbuf at this point so get_next_slot() didn't have
as large of buffer as it expected. So all but the first set_vertex_data()
was writing out of bounds.
Also added some comments.
