Getting some stuff ready for a maintenance release.
RuntimeDepends and BuildDependsOnly: false
Some cleanup and TODOs
Make 'dumpinfo' command aware of RuntimeDepends
Add a TODO note to the Shlibs.m code

There already is a little bit of RuntimeDepends code in there, put in
there by somebody else in the past. However, it seems to be incomplete
and possibly partially incorrect. Alas, the code in Shlibs.pm seems to
be completely unused at the time, so I am not worrying about this for
now.
Add RuntimeDepends support to the package system / engine.

Also add FIXME/TODO comments, and remove get_binary_depends function.
Remove unused resolve_conflicts()
Allow RuntimeDepends on fink-obsolete-packages
