=for apidoc mro_package_moved
Call this function to signal to a stash that it has been assigned to
another spot in the stash hierarchy. C<stash> is the stash that has been
assigned. C<oldstash> is the stash it replaces, if any. C<gv> is the glob
that is actually being assigned to.
This can also be called with a null first argument to
indicate that C<oldstash> has been deleted.
This function invalidates isa caches on the old stash, on all subpackages
nested inside it, and on the subclasses of all those, including
non-existent packages that have corresponding entries in C<stash>.
It also sets the effective names (C<HvENAME>) on all the stashes as
appropriate.
If the C<gv> is present and is not in the symbol table, then this function
simply returns. This checked will be skipped if C<flags & 1>.
