526231bc22 initialize store_t::name
the field is marked foreign (for the drivers), so a recycled store may
contain an old pointer in it. that would make our error path crash.

3d5539bb63 detect inconsistent state of highest assigned UID
the highest assigned UID must always be at least as high as the highest
actually found UID, as otherwise we'd hand out duplicate UIDs at some
point. also, getting into such a state in the first place indicates some
potentially serious trouble, or at least external interference (e.g.,
moving/copying a message from another folder without giving it a
pristine filename).

8513358e0a zero-terminate imap literals
now that we properly support literals for strings, we must expect that
the consumer code will use them as strings.

4ab12ae76e don't lie about the default of User
unlike the isync wrapper, mbsync does not have a default for the IMAP
user. the remote user seldomly matches the local one, so "forwarding" it
is more confusing than helpful.

2d4bc1e613 error-check committing of sync state
a failure here is rather unlikely, but let's be pedantic.
a failure is not fatal (we'll just enter the journal replay path next
time), so only print warnings.

d7d5fd20bc fix "inverse copy&pasto" in account labeling code
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.

c5f2943ff6 don't crash in message expiration debug print
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.

d34baeb886 fix hypothetical buffer overflows
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.

19d86d2aa9 rework maildir store mapping
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.

f4a192f375 don't error out if we don't get an X-TUID header
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.

c47ee1c8c4 fix error paths wrt sync drivers, take 3
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.
