When purging the program hash table, the refcount _should_ be one since
the program is referenced by the hash table. Need to explicitly set to
zero before calling delete().
Also, purge high-level shader hash tables before low-level program hash tables.
The refcounting bug was causing a memleak (unfreed programs).
The old parameter list sharing is not needed since the change in how
uniforms are handled.
Previously, the shader linker combined the uniforms used by the vertex and
fragment shaders into a combined set of uniforms. This made the implementation
of glUniform*() simple, but was rather inefficient otherwise. Now each shader
gets its own set of uniforms (no more modelview matrix showing up in the
fragment shader uniforms, for example).

Since the only valid consumer of the DRI drivers is the X.Org xserver,
this changes the default DRI driver directory to match xorg-server:
${libdir}/dri. The old default of /usr/X11R6/modules/dri was wrong for
nearly all current systems.
This commit adds an autoconf macro, MESA_PIC_FLAGS, which sets the
PIC flags according to platform and static/shared setting. The platform
specifics are taken straight from libtool.m4 and stripped down to just
the flags and platforms we cover in Mesa. This should hopefully make it
possible to use autoconf on non-GCC platforms.
The macro is added external to configure.ac in acinclude.m4 since it's
pretty bloated.
Note to BSDers: Previously, x86 defaulted to non-PIC on FreeBSD. I
didn't carry that preference into this macro. Instead, you can just use
--disable-pic where desired.
Mostly some pedantic changes such that `make clean' always ignores
errors. Also changed the top clean target to do the `touch
configs/current' dance instead of realclean.
Currently, there is a single path in src/mesa/Makefile to install that
has a few conditionals in it. This commit changes install to act like
default where we loop over $(DRIVER_DIRS), deciding what to do.
A new target, install-headers, has been broken out to accomodate
installing a standalone OSMesa where neither libGL or gl.pc are wanted.
