Log:

Add utility method for handling one-off command line options

This adds the CommandLineArg::AllowOneOf method for handling
applications with several mutually exclusive utility functions.  This
takes a list of CommandLineArg pointers, and handles setting the
interdependencies.

Adds use in mythbackend, mythcommflag, mythmetadatalookup, and
mythshutdown.
