pop client and movemail: bugfixes

* libproto/pop/mbox.c (pop_close): Destroy the cached data.
(pop_destroy): Avoid freeing the same data twice.
(pop_body_get_stream,pop_body_size,pop_body_lines): Owner is mu_message_t.
(pop_create_body): Change the owner of the created mu_body_t object.

* movemail/movemail.c: Correctly close both mailboxes if unhandled errors
occur.
