>Description:
This patch add another pkg_* program: pkg_updating
pkg_updating scan the installed ports and show all UPDATING entries that
affect one of the installed ports, and are relevant on the given machine.
The idea of pkg_updating is from the project idea page:
http://www.freebsd.org/projects/ideas/#p-ports-updating
