pkg, info: remember installed packages "replaces"

"replaces" is now turned to a full dependency type list, so you can
make package overwrite files only certain versions of the package
(though, we should probably take this into account already at solution
calculation phase).

Also make 'info --replaces' print the "replaces" of the package.

This is in preparation for the policy package support, which still
requires "replacement priority" field to decide which packages' files
get the preference.
