[Dovecot] using dsync to convert mailboxes looses caching options

[Mark Zealey]

With 2.0.16 hdr.xxx fields get copied fine (but of course without timestamp). With the patch you provided they don't get copied whether using mirror or backup & starting from scratch. I'm doing a Maildir to sdbox migration otherwise don't think I'm doing anytihng strange.

OK I'll test the header copying more fully. The reason we want to preserve caching decisions is to avoid an IO storm when users log in to their mailboxes after an sdbox upgrade so it would be great to be able to have some way to warm caches.
