Eliminated maxima-run-lisp; please test acl6 and openmcl

I have just committed a some changes to cvs that completely eliminate
the usage of the maxima-run-lisp script. In the process, I managed to
make Makefile.am 35 lines shorter than it was when it used
maxima-run-lisp.

The modified files (Makefile.am and maxima.in) should now be easier to
modify. More importantly, the most significant bottleneck in bringing
windows into parity with Unix(-like) systems has been eliminated. The
remaining steps in this task are to move as much as possible of the
command-line processing functionality into Lisp, then write the bat file
equivalent of the simplified Bourne shell script.

I have tested the build under clisp, gcl (with and without alt-link),
cmucl and sbcl. I don't have access to acl6 or openmcl, so I would
appreciate it if someone would verify that make and make check work with
those systems.

P.S. I originally introduced the (maxima-)run-lisp script in hopes that
it was a wheel I could avoid re-inventing. In the end, the run-lisp
script did nothing but make life more difficult than it would have been
otherwise. Live and learn.

P.P.S. I haven't removed maxima-run-lisp itself from cvs. I will do so
after I'm sure all the bugs have been worked out of the new system.
