XSB Src (SVN)-old

Fix one place where parameterized module names were not handled correctly.
(And cleanup patch in cp_opt.P to make testing of internal variables more
precise.)

File had syntax error and wouldn't read correctly. Don't know exactly what was
meant for it to compile (or maybe not?), but tired to do minimal change to
make it syntactially correct.

recompiled windows dlls for xsb packages -- to account for the changes that Teri made in cinterf.

turns out the linix/mac version of makexsb clean was not removing the .so/dylic/xwam files from config/arch.../lib, which was sometimes leading to false bug reports.

Minor change to handle unsigned arity more cleanly/simply.

uncommented xsb_patch_version in version.sh because otherwise the version string looks ugly (has a trailing dot).
Maybe somebody would want to fix that but until then xsb_patch_version shodn't be empty.
Updates related config files, which are generated by configure.

Recoded nec_different_xwam_files to be simpler and not use
raw integers where clearer options are available (as Michael suggested.)

Minor casts or change of decls to eliminate warnings from MSVC.

table_once is now opaque.

Fixed some old tests to represent actions of large arity terms (some tests succeed now, rather than throwing erors)
and added a couple of new ones.
