6b7b2b1106 always get slave flags when we are expiring 
even if we are not propagating new messages, the appearance of new
messages on the slave can lead to expiring older messages. for that, we
need to know their importance, and thus flags.

the alternative would be not doing an expiration run when not fetching
new messages, but that would mean more conditionals all over the place.
as the decision is somewhat arbitrary, just do the simpler thing.

the header is not space-critical, so use proper name-value pairs.

55e65147df fix compilation with older gcc versions 
the warning suppression pragma within function scope is apparently a new

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.

a893cba483 fix enum abuse 
amends 9c86ec344.

S_FIND was for the sync record status field. it has no business in the
sync vars status fields. its value coincided with ST_SELECTED, which
luckily only means that we always tried to match up TUIDs even if there
was nothing to do.

the need for TUID matching arises in two mostly independent
circumstances, so add two separate flags ST_FIND_{OLD,NEW}.

9261897629 don't record newuid in the sync state 
this value is only ever used to find just pushed messages by TUID, so we
can simply use the UIDNEXT value from before we started pushing - and of
course, we need to record that in the journal. it makes no sense to log
the new value after completing a search, as there won't be a next search
before we push the next messages.

15d57b95b7 make paths relative to CWD, after all 
the test suite actually relies on it. it would be possible to adjust it,
but there is not much reason to make paths relative to HOME (as we
support convenient tilde expansion). so use the least invasive approach,
which is simply the old behavior. adjust the documentation accordingly.

7ba7be111e improve socket error reporting

acb1c870b4 rewrite SSL certificate verification. again. 
leave all the hard work to OpenSSL. this has several consequences:
- certificate chain validation actually works instead of throwing
  around error 20
- the interactive approval is gone. i don't expect it to be useful

8310cf78ac fix CVE-2013-0289: add SSL subject verification 
we did not check a valid certificate's subject at all so far.
this is no problem if the certificate file contains only exactly the
wanted host's certificate - before revision 04fdf7d1 (dec 2000, < v0.4),
this was even enforced (more or less - if the peer cert had been
signed directly by a root cert, it would be accepted as well).
however, when the file contains root certificates (like the system-wide
certificate file typically does), any host with a valid certificate
could pretend to be the wanted host.

9bbb02b8fd Revert "fix UIDNEXT handling" 
in fact, UIDNEXT (and UIDVALIDITY) null is *not* allowed (see RFC3501

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.

233f563569 deal with concurrent maildir modifications during listing 
files may be renamed (due to new -> cur transition or flag changes),
which may lead to two effects if ignored:
- we see both the old and the new name, so we report a spurious
  duplicate UID
- we see neither name, so we report a spurious deletion

as countermeasure, record and compare directory modification times. upon
mismatch, we just start over - as usual.

- 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).

ea951a697f fix error paths wrt sync drivers, take 2 
synchronous error codes which are passed through callbacks aren't a
particularly good idea, after all: latest when the callback does stuff
which does not concern the caller, the return code becomes ambiguous.
instead, protect the sync_vars object with a refcount when invoking
driver functions from loops, as the callbacks they call could invalidate
the object and we would have no way of knowing that the loop should be
aborted prematurely. the upcoming async imap driver will also need a
refcount to protect the cancelation marker of the imap socket dispatcher
loop.

9b7c09e4b6 enable the old account naming scheme to deal with duplicated ip

this is not incompatible - previously, it would just create garbage.

aea4be19e3 create more descriptive account names, so password prompts look sane. 
the channel names follow the old scheme, though - they are used to
compose sync state file names, and i don't feel like writing a migrator
for this.

bc39f10a1e lock the sync state open the journal before opening the master. this is 
a bit ugly for the "SyncState *" case, as we have to create a directory
without making it a maildir right away. however, this makes the code
quite a bit simpler to understand and simpler to parallelize.
