description:
Add new metadata: PREV_PKGPATH and SUPERSEDES.
These will be available from pkg_summary(5) database.
To be used to find previous packages when a package is moved
or renamed. (Even though that is not recommended.)

Documented in pkgsrc Guide and in the pkg_summary(5) manual page.

Upcoming commit will have some packages modified to add them.
