This is merges the old "rsalz-monolith" branch over to master.  The biggest
change is that option parsing switch from cascasding 'else if strcmp("-foo")'
to a utility routine and somethin akin to getopt.  Also, an error in the
command line no longer prints the full summary; use -help (or --help :)
for that.  There have been many other changes and code-cleanup, see
bullet list below.

Special thanks to Matt for the long and detailed code review.

This compiles and runs on Linux, and external applications have no

external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
