Sets additional conditions for when a wire is trimmed 

This adds a set of conditions that will prevent a wire from being
automatically trimmed.  Wires that are currently being moved or are
newly created or are explicitly avoided will not be removed.  This also
adds a function to set a flag on items in a block.
