Code reorganization: split gallium and mesa makefiles.
In other words, don't build src/gallium source code from within src/mesa/Makefile.
Also, allow to customize which gallium auxiliary dirs, driver driver, winsys
dirs get built from the config/* files.
Update the Makefiles and includes for the new paths.
Note that there hasn't been no separation of the Makefiles yet, and make is
jumping all over the place. That will be taken care shortly. But for now, make
should work. It was tested with linux and linux-dri. Linux-cell and linux-llvm
might require some minor tweaks.
Make sure EXTRA_LIB_PATH is used with all the LIB_DEPS. Re-order some
of the options and tweak the whitespace to make the various LIB_DEPS
more readable. This makes building for Cell on x86 a bit easier and
doesn't seem to effect other builds.
Removing the paths on certain commands (e.g., ppu32-gcc) and removing
-I/usr/include makes it possible to build for Cell on both PowerPC and
x86 hosts.
libspe is deprecated in Cell SDK 2.1, and it is removed in Cell SDK 3.0.
This patch ports the existing libspe-based code to libspe2. Some error
checking (eh-hem) would be nice.
This is appropriate as this is not a "pipe driver for the i915" as the
old name would suggest, but rather a dri driver that can provide "winsys"
backends to softpipe/i915/i965/etc pipe drivers, running under the
intel DDX, drm, etc.
It also frees up the i915pipe name for something more appropriate, ie
mesa/pipe/i915pipe.
