the code was copied and the original adjusted ... but not quite
completely.
this means that clashing server names never really worked since - not
that i would have expected this to be a particularly common
configuration to start with. :D
also added comments explaining why there are two implementations of the
same thing.

we would try to print the uids from the non-existing srec of unpaired
messages while preparing expiration.
this would happen only if a) MaxMessages was configured and b) new
messages appeared on the slave but we were not pushing, so it's a bit of
a corner case.

this would happen in the absurd corner case that the response code is
properly terminated with a closing bracket, but the atom itself is an
unterminated double-quoted string.
NOT found by coverity.
if something managed to make the maildir .uidvalidity files big enough
(possible only by appending garbage or scrambling them alltogether), we
would overflow the read buffer by one when appending the terminating
null.
this is not expected to have any real-world impact.

for some reason lost in history, the prime_deltas were actually wrong,
leading to using composite numbers.
the right sequence is available at http://oeis.org/A092131.
the trivial approach of having "home" and "root" stores produced ugly
results, and totally failed with the introduction of nested folder
handling.
instead, create a store per local directory, just as one would manually.

makes for leaner Channel sections.
note: the global delete and expunge variables exist so the command line
can override the config file despite the otherwise backwards behavior.
the BODY[] item in the FETCH response corresponds to what we requested,
and its presence doesn't imply that it actually contains anything useful
- new messages may appear in the mailbox in addition to those we stored
ourselves, and these will obviously have no TUID.
the global timezone variable is glibc-specific.
so use timegm() instead of mktime() for the conversion.
as that is specific to the BSDs and glibc, provide a fallback.
amends 62a6099.
by putting the message propagation last, d3f634702 uncovered a
long-standing problem: we might have closed the source store before all
messages were propagated from it.
msgs_copied() was not checked at all, and msgs_flags_set() was doing it
wrong (sync_close() was not checked).
instead of trying to fix/extend the msgs_flags_set() model (ref-counting
and cancelation checking in lower-level functions, and return values to
propagate the status), place the refs/derefs around higher-level scopes
and do the checking only there. this is effectively simpler, and does
away with some obscure macros.
as the named boxes are the same on both sides, they logically make
sense only when the channel is in that mode anyway, which is the case
when using patterns.
we would see the recent timestamp of the creation and conclude that
something is going on, so we'd wait. this is obviously nonsense.
as we know that a freshly created mailbox is empty, simply skip the
message scan alltogether.
as we now don't actually start propagating new messages until all TUIDs
have been generated, it's sufficient to sync just once. this makes it
a cheap operation, so we can do it at SYNC_NORMAL level already.
