scons: Always build softpipe and llvmpipe (when llvm available).
These are our reference software rasterizers. They can build everywhere
and are a precious debugging tool.
Making them always present immensily simplifies the scons logic.
If people want to avoid building it is still possible to pass
direcotries and target names to scons to narrow the build.
Now that draw depends on llvm it is very difficult to correctly handle
broken llvm installations. Either the user requests LLVM and it needs to
supply a working installation. Or it doesn't, and it gets no LLVM
accelerate pipe drivers.
gallium: new raw gallium interface to support standalone tests
Provides basic window system integration behind a simple interface,
allowing tests to be written without dependency on either the driver
or window system.
With a lot of work, could turn into something like glut for gallium.
There are so many state trackers and winsys that rely on it for debug
building, and trace can really build anywhere and is thin so there's no
point is making it an option.
Based on Xavier Chantry <chantry.xavier@gmail.com>'s patch:
"I also removed the trace check in xlib SConscript which is now useless, and
that script seems to deal with the cell driver, so I added cell in the check
for supported drivers."
llvmpipe: export the tgsi translation code to a common layer
the llvmpipe tgsi translation is a lot more complete than what was in
gallivm so replacing the latter with the former. this is needed since
the draw llvm paths will use the same code. effectively the proven
llvmpipe code becomes gallivm.
gallium: Provide alternative stdint.h and stdbool.h C99 headers, instead of ad-hoc definitions.
Everybody is using the C99's integer types. Everybody except Microsoft,
which in turns means everybody is including their own definitions of C99
integer types for MSVC, causing duplicate definitions when linking two
projects. This is the case of building Gallium and LLVM with MSVC.
Shipping alternative stdint.h and stdbool.h headers for MSVC allows us
to share a single definition. It also removes clutter from the Gallium
headers.
This is a substantial reorganization, This particular commit enables:
- building the progs for unices platforms
- glew is now built as a shared library (it is the default, and it is
inconvenient and pointless to shift away from that default)
- all progs get built by default
But there are some missing symbols, "nm -u i965_dri.so"

The driver never work with real hardware and has
bitrotted for quite some time now, might as well
drop it. If somebody wants to look at it just use git.
This driver does no transformation of the gallium calls
going to the real driver, like the identity matrix. It is
intended to be the basis for transforming and/or debug
drivers like trace and rbug.
Authors of this patch are:
Michal Krol, orignal heavy lifting.
José Fonesca, object wrapping code stolen from trace.
Jakob Bornecrantz, put it all toghether and renamed a stuff.
