4ab55dc468 don't try to fetch status of minus one message
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.

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.

96be183acb rename sync_vars_t::uidnext => newuid & fix comment
the purpose of this variable is to hold the UIDNEXT value from before
we started pushing new messages, i.e., the minimal uid we can expect
them to have.

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.

This reverts commit da5ce5d8f4.

7ba7be111e improve socket error reporting
always use getsockopt() to query the meaning of POLLERR, rather than
reporting "Unidentified socket error".
this is unlikely to have any effect when using select(), as that one
pretty much never signals exceptional conditions.

37a28d8133 improve socket connect() error reporting with poll()
turns out that poll() may (and on linux does) signal POLLERR on
connection failure. this is unlike select(), which is specified to
signal write readiness in every case.
consequently, check whether we are connecting before checking for
POLLERR.

da5ce5d8f4 make path expansion match docu: paths are relative to ~
the current behavior of being relative to the current directory sort of
makes no sense, and contradicts the docu.

89add4f330 downcast time_t to long for printing
time_t may be long long. to keep the sprintf format strings simple, just
downcast - this is not going to be a problem for the next 30 years, and
until then long will be 64-bit everywhere anyway.

suggested 3.5 years ago by Antoine Reilles <tonio@NetBSD.org>.

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
  anyway, as mbsync is mostly a batch tool
- the code is much shorter

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.

flattened sub-folders of INBOX actually end up in Path, so list that
instead.

66895f9cce try harder to list all necessary boxes
the pattern "INB*" may or may not refer to something in the INBOX. even
just "*" may. so list both the INBOX and the Path in case of
uncertainty.

49223b2df2 avoid that a system crash can cause messages to be propagated twice
fdatasync() the journal after creating the pair record and recording
the TUID, but before the message propagation actually starts.

all other writes to the journal are not flushed, as they will at worst
cause some unnecessary network traffic without visible effect.

a326bf2f58 avoid that a system crash can lose mails
this fixes two possible failure scenarios:
- if the journal is committed but the mails are not, the missing files
  would be erroneously interpreted as deletions which would be
  propagated
- less seriously, if the mail files' meta data was committed but the
  file contents were not, we would end up with empty files, which would
  have to be re-fetched "behind mbsync's back" (just deleting the files
  would not work - see above)

df6c3b64b7 avoid that a system crash can clobber the sync state file
make sure that the new state is committed to disk before overwriting the
old version - by default meta data is committed first, so we may end up
with no valid state at all otherwise.

6f2160f136 remove todo about case insensitive INBOX
this is *our* magic string, not IMAP's.
ok, admittedly, we *also* send it to IMAP, but that's just convenience.
actually making it case insensitive would improve interoperability with
thunderbird (which interprets INBOX even if qualified), but would break
existing setups (including mine).

6d49c343fc use a hash table for message => sync record lookup
this removes the pathological O(<number of sync records> * <number of
new messages>) case at the cost of being a bit more cpu-intensive (but
O(<number of all messages>)) for old messages.
