This prevents the driver from discarding a buffer when the whole buffer
is mapped for writing, but only a portion is effectively written.
This is a temporary fix, because WRITE shouldn't imply DISCARD.
The full fix implies using PIPE_BUFFER_USAGE_DISCARD, throughout
the code, and will go only into master.
This adds two --with configure options for setting defines for
MAX_WIDTH and MAX_HEIGHT. It's conceivably just as easy to define
these in CFLAGS manually, but this way users don't need to know
about internal Mesa details.
Patch updated by BrianP to set DEFINES, not CFLAGS.

This previously was used only for decomposed (POINT/LINE/TRI) primitives,
but for some time a full range of primitives could end up in here.
Fixes trivial/lineloop-clip on softpipe, among others.

We now handle the case of blitting Z+stencil to/from combined Z/stencil
surfaces. But Z-only or stencil-only and separate depth/stencil surfaces
are not yet implemented.
Need to check for Y inversion separately for src/dest buffers.
If both the src and dest regions are upside down, make them right-side
up for a better chance at a fast path.
progs/tests/copypixrate -blit is much faster now.
The comment disagreed with the code, and nicely drew my eyes to what was
going wrong.

This fixes jerkiness in doom3 and other apps since the kernel change to
throttle less absurdly, which led to a thundering herd of frames.
Because this is a rather minimal fix, there is at least one downside: If
the whole scene completes in one batchbuffer, we'll end up stalling the GPU.
Thanks to Michel Dänzer for suggesting using glFlush to signal frame end
instead of going to all the effort of adding a new DRI2 extension.

Funny thing is I annotated this dependency in
e5f63c403b, but didn't actually use it.

Instead of relying on the Makefile to always generate $(TOP)/$(LIB_DIR),
just have mklib handle creating the directory. This should fix any races
when using parallel make.

Compiling mesa on a system with no X headers installed in the default
include paths fails due to missing X11 includes. The header includes are
picked up by configure but not applied.

This fixes the problem that first frame would report bogus usage values.
Problem was caused because get_frame_usage returned data from previous buffer
swap.

Windows opengl32.dll calls glFinish prior to every swapbuffers, which
makes it pretty hard to get decent performance...
Work around by mapping finish to flush on PIPE_OS_WINDOWS. This is
conformant, though it might confuse poorly-written benchmarks which
attempt to measure a single event rather than figuring out the rate of
continuous processing.
