b142778e56 match flag names in man page
"Full" is an alias for "All", but let's stick to one.

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.

c23d251092 consider hierarchy delimiter flattening when deciding what to list
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.

9bbb02b8fd Revert "fix UIDNEXT handling"
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.

This reverts commit e1fa867 and most of 39006d7.

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.

3386285205 make maildir uidvalidity change fatal
it's best to give the user a chance to fix it rather than completely
messing up the syncstate by re-enumerating the UIDs.
