- cint/*:  Revamped the launch-scheme for ginaccint.bin.  It must be done
  by a binary executable and not by a script to ensure users can write
  shebang-scripts.
- cint/*:  Added a testsuite which hopefully passes (some lucky day).
- cint/ginaccint.bin: For this to work we needed a --silent command line
  switch.
- configure.in, Makefile.am, cint/Makefile.am: account for new launchers.
- ginac/matrix.cpp, ginac/matrix.h: removed confusing ffe_get() and ffe_set()
  routines since they counted the non-standard way.
- config.guess, config.sub: Updated to new versions from FSF.
- others files: Changes triggered.
