Major hack of mkdef.pl. There should be no more need to redo the

process when some symbols are missing.  Instead, all needed info is
saved in the .num files, including what conditions are needed for a
specific symbol to exist.

This was needed for the work I'm doing with shared libraries under
VMS.

+  *) Major change in util/mkdef.pl to include extra information
+     about each symbol, as well as presentig variables as well
+     as functions.  This change means that there's n more need
+     to rebuild the .num files when some algorithms are excluded.
+     [Richard Levitte]

   *) Allow the verify time to be set by an application,
      rather than always using the current time.
