Created a configure time test to see if clang will compile ICG correctly.
If the compilation fails, an error message telling the user to go download
clang/llvm from llvm.org is show.

If no argument is given with --with-gsl or --with-hdf5 we search
/usr/include for the proper header files. If found we set the
configure variables for these packages to /usr. If not found we
emit an error message.

Taking in the latest er7_utils directory and adding it into Trick in the
same location it was as an external repository. Made one change to
the files_to_ICG.hh file in the repository to remove the CheckpointHelper
header files. Those go in the Trick files_to_ICG.hh file.

We were using "llvm-config --bindir" to set the path for clang. But
on some systems clang is not in that directory. Changed the configure
script to search for clang in the bindir first, if not found, search
the normal locations.
refs #130
Added a configure check for clang and llvm-config. If llvm-config exists
then we check for the libraries in the libdir returned by llvm-config.
All of these must be present for configure to pass.

So I found that I didn't write many of the autoconf rules correctly including
the one searching for motif. I also messed up the checks for bison, flex, and
perl. I added new rules to search for Xwindows headers and libraries. The
motif rule is only executed if we find fermi-ware where it is used.

Added AX_PTHREAD to the configure.ac script. This change forces us to
have install-sh, config.sub and some other autoconf files. Created
an autoconf directory to hold these files. Changed the makefiles to
use the PTHREAD variables coming out of configure.
