Ensure reverse-dependencies of superseded packages are always checked.

Browse Source 
If a binary package being processed as part of a hint has moved source
packages, the installability checks for the new version of the binary
need to include the reverse-dependency information from the previous
version.  In order to allow this, modify doop_source() to take an
optional list of undo information and iter_packages() to pass such
a list when processing hints.
