mesa: more complete fix for transform_invarient glitches
Add a new flag mvp_with_dp4 in the context, and use that to switch
both ffvertex.c and programopt.c vertex transformation code to
either DP4 or MUL/MAD implementations.
mesa/main: set PREFER_DP4 to match position_invarient code
This is a quick fix for z fighting in quake4 caused by the mismatch
between vertex transformation here and in the position_invarient code.
Full fix would be to make this driver-tunable and adjust both
position_invarient and ffvertex_prog.c code to respect driver
preferences.
gallium/tgsi: hack around linker/archiver breakage
Add a dummy function which exists only so that tgsi_text_translate()
doesn't get magic-ed out of the libtgsi.a archive by the build system.
Don't remove unless you know this has been fixed - check on
mingw/scons builds as well.
st: create renderbuffer's pipe_surface in st_render_texture()
Previously we created the pipe_surface during framebuffer validation.
But if we did a glCopyTex[Sub]Image() before anything else we wouldn't yet
have the surface. This fixes that.
When building mangled Mesa on Darwin, the exported symbols are
named `_mgluWhatever' instead of simply `_gluWhatever'. When
using a list of exported symbols via the system ld's
`-exported_symbols_list' command line option (as done by mklib),
this resulted in error messages about exporting symbols which do
not exist.
Fortunately the file format accepts simple wildcards. This throws
a wildcard so that the symbol list will match both the mangled and
non-mangled names, preventing the warning and actually exporting
the correct symbols in one shot.
I don't think anyone besides a developer would ever want to use the demo
egl driver. Furthermore, egl would only ever load demodriver if it was
set via EGL_DRIVER in the environment. In that case, I think you can
point it to your mesa source directory.
Previously the pkg-config output files would contain e.g. `-lGL'
and `-lGLU', even if the user modified their configuration to
build libraries with different names. This modifies the
pkg-config inputs, and corresponding makery, so that modifying the
output library name will cause the appropriate updated name to
appear in the pkg-config `-l' option.

tgsi: added tgsi_check_soa_dependencies() and related debug code (disabled)
The TGSI interpeter operates in SOA style. We need to check for data
dependencies in instructions which read from and write to the same register.
For now just adding some debug code to detect that condition. Actual fixes
to follow.
