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.
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.
the warning suppression pragma within function scope is apparently a new
thing.
as i don't want to disable the check for the entire function (even if
this currently would make no difference), just use a wrapper function
to suppress the format string check.
this would happen if we were trying to find newly pushed messages, but
none actually arrived.
as imap's ranges are not ordered, this would actually fetch one message.
in fact, UIDNEXT (and UIDVALIDITY) null is *not* allowed (see RFC3501
section 9). them popping up nonetheless was a dovecot bug (which would
also confuse dovecot itself).
having it in as a workaround was no good either, as quite some other
code in mbsync assumes that UIDs are not null.

instead of SEARCHing every single message (which is slow and happens to
be unreliabe with M$ Exchange 2010), just FETCH the new messages from
the mailbox - the ones we just appended will be amongst them.
- introduce sys_error() and use it instead of perror() and
error(strerror()) in all expected error conditions
- perror() is used only for "something's really wrong with the system"
kind of errors
- file names, etc. are quoted if they are not validated yet, so e.g. an
empty string becomes immediately obvious
- improve and unify language
- add missing newlines
- asynchronous sockets using an event loop
- connect & starttls have completion callback parameters
- callbacks for notification about filled input buffer and emptied
output buffer
- unsent imap command queue
- used when
- socket output buffer is non-empty
- number of commands in flight exceeds limit
- last sent command requires round-trip
- command has a dependency on completion of previous command
- trashnc is tri-state so only a single "scout" trash APPEND/COPY is
sent at first. a possibly resulting CREATE is injected in front of
the remaining trash commands, so they can succeed (or be cancel()d
if it fails).
- queue's presence necessitates imap_cancel implementation
