The standard autoconf initialization macros require that config.guess,
config.sub and install-sh exist. The config.* scripts are from gnulib
HEAD, and the install-sh script is from automake HEAD.

Most of the programs list their dependencies on the Mesa libraries in
their Makefiles. This works with the default configuration where
APP_LIB_DEPS only lists external libraries. This changes the
linux-osmesa configs and the osdemos Makefile to follow that convention.

Some cleanup of the Makefile is also added to refer to the GL libraries
through the existing variables rather than hardcoding their names.

Linking of the programs breaks when using a static libGL and the GNU ld
option --as-needed. This is because libXext is needed for the XShm
functions.

This increases the reference count for the driver binary, preventing it from
getting unloaded prematurely in driDestroyDisplay. See

I had forgotten part of brw_state_cache.c that made this fix not relevant for
master (last_addr comparison and flagging based on cache id).

This reverts commit a4642f3d.

Otherwise, choosing a new program wouldn't necessarily update the state, and
and an old program could be executed, leading to various sorts of pretty
pictures or hangs.

Pixel Mask Copy is modified as the pixel shader thread

Also use tx_table_be for VALID_FORMAT, in case r200SetTexImages ever gets
