XSB Src (SVN)-old

Conditioned search_file to find non-suffixed files/directories to be done
only for imports from usermod(..).

Modified loader to search for un-suffixed files/directories only after
searching all directories for suffixed files/directories. This should
be backwards compatible (for non-aborting programs) and should fix
Flora's issues with a previous change.

Removed exports of undefined predicates.

Removed exported symbols that were not defined.
Uncovered by compiler change to flag such instances.
Also minor change to loader to allow search_module to find files
(or directories) without suffixes. (To be used for importing of data files.)
(Also a spurious different xwam file that I don't know why should differ.)

Minor bug fix in handling of table_index transformation.
Added assumption that exported symbols are predicates so useinfer flags
undefined exports.
Removed some exports of undefined predicates uncovered by previous change.

replaced message/1 with respectful_message/1 - one that respects the quietload flag (which suppresses printing the loading messages)

Updates to make psc_renaming work for MT engine, and a couple of small documentation changes.

Some set_alt_semantics stuff.

updated DLLs for 64 and 32

Also getting rid of these...
