Going back to unmodified 2-Clause BSD License.

* LICENSE: Reverted to Two-Clause BSD license. The
copyright of the Linenoise library are included, because
it uses exactly the same license. A note is added
about MPI being in the public domain.

* LICENSE-CYG: Revised text to clarify the situation that
Cygnal is only bundled with a particular Windows build of TXR.

* METALICENSE: Revised text. All references to modifications
to the BSD license are removed. Gives pointers to the MPI and linenoise
license files. Notes that linenoise is under the Two-Clause BSD also.
Makes a note about Cygnal and points to LICENSE-CYG.

* inst.nsi: Remove the text which tells the user that
use of the program requires agreement with the license;
refer only to redistribution. The "Agree" buttons are renamed
"Acknowledge".

* mpi/make-logtab, mpi/mpi.c, mpi/mpi.h, mpi/mplogic.c,
mpi/mplogic.h: Remove copyright notices and "all rights
reserved", since the author had placed this into the public
domain, as made explicit in the README file.
