When synclabels config flag is set to "yes" for the GMail repo,
offlineimap fetches the message labels along with the messages, and
embeds them into the body under the header X-Keywords (or whatever
'labelsheader' was set to), as a comma separated list.
It also adds an extra pass to savemessageto, that performs label
synchronization on existing messages from GMail to local, the same way
it is done with flags.
We also introduce GmailMaildir repository that adds functionality to
change message labels. It keeps track of messages modification time,
so one can quickly detect when the labels may have changed.

In preparation for GMail label sync, we had split our some functionality
that will be needed further into their own functions. This also permitted

Since we just do multiple passes for saving the message without
actually modifying its content (apart from header insertion that
is CRLF-clean), we can change line ends to the proper CRLF just
once.
And we can also get message's date only once too.

self._expecting_data was used both as the expected data length and the
flag that we expect some data. This obviously fails when advertized
data length is zero, so self._expecting_data_len was introduced to
hold the length of the expected data and self._expecting_data was left
as the flag that we expect the data to come.

Global or per-repository option utime_from_message tells OfflineIMAP
to set file modification time of messages pushed from one repository
to another basing on the message's "Date" header.
This is useful if you are doing some processing/finding on your
Maildir (for example, finding messages older than 3 months),
without parsing each file/message content.

It's nice to set up an ssh tunnel command which forwards an IMAP tcp
port inside an encrypted session, e.g. with ssh's "-W" flag. In this
case the tunnelled connection still requires authentication inside
IMAP session, because this is transport-only tunnel that substitutes
normal TCP/SSL connection.
New directive, 'transporttunnel' was added: it specifies the command
that will create the tunnel. Only one type of tunnel must be
specified for a single repository: we can't have both preauthenticated
and transport-type tunnels, they won't chain together.

- this method isn't as deprecated as IMAP LOGIN;
- it allows to keep hashed passwords on the server side;
- it has the ability to specify that the remote identity
is different from authenticating username, so it even
can be useful in some cases (e.g., migrated mailboxes);
configuration variable "remote_identity" was introduced
to leverage this functionality.

- created helper routine that will do authentication;
- routine tries each method in turn, first successful
one terminates it: makes things easier to read
and handle;
- renamed plainauth() inside offlineimap/imapserver.py
to loginauth(): the function does IMAP LOGIN authentication
and there is PLAIN SASL method, so previous name was
a bit misleading;
- slightly improved error reporting: all exceptions during
authentication will be reported at the end of the run;
- now loginauth() is never called if LOGINDISABLED is advertized
by the server; it used to be invoked unconditionally when
CRAM-MD5 fails, but we should respect server's opinion on
how to handle its users.

IMAP servers can return `NO` responses to the `APPEND` command,
e.g. here's an example response from Groupwise's IMAP server:
NO APPEND The 1500 MB storage limit has been exceeded.
In this case, savemessage() should abort the repository sync rather
than returning UID 0 which would cause the local copy of the message
being saved to get irreversibly deleted.

mutt-sidebar and, probably, other MUA show mailboxes in the order
they are listed in the file written by mbnames. Therefore, to allow
customization of the order with which mailboxes are listed, introduce
the new 'sort_keyfunc' directive in the [mbnames] section.
'sort_keyfunc' must be a function that will be called once for each
mailbox. It must accept the only argument -- a dict with 2 items,
'accountname' and 'foldername', and should return an object that
will be used as the sorting key for each mailbox.
Default key function returns (d['accountname'], d['foldername']),
thus sorting by account name and then by the folder name.

The problem lies in the fact that offlineimap.folder.Base's method
syncmessagesto_copy() uses threaded code everytime it is suggested by
the derived class's suggeststhreads() (currently, only IMAP does this
suggestion), but offlineimap/init.py will not spawn the
exitnotifymonitorloop() from offlineimap.threadutil.
The root cause is that ExitNotifyThread-derived threads need
offlineimap.threadutil's exitnotifymonitorloop() to be running the
cleaner for the exitthreads Queue(), because it fills the queue via
the run() method from this class: it wants to put() itself to the
Queue on exit, so when no exitnotifymonitorloop() is running, the
queue will fill up. And if this thread is an instance of
InstanceLimitedThread that hits the limit on the number of threads,
then it will hold the instancelimitedsems[] semaphore will prevent
other InstanceLimitedThread()s of the same name to pass its start()
method.
The fix is to avoid using threaded code if we're running
single-threaded.

offlineimap has several frontends that encourage running it from a
terminal under an X session. When X session closes for a system
shutdown, the terminals exit, after sending SIGHUP to their children.
Previously SIGHUP was treated to be equivalent to SIGUSR1, i.e. wake
up and sync all accounts. This causes delays during shutdown.
According to Wikipedia [0], SIGHUP has been repurposed from a
historical meaning to one of:
* re-read configuration files, or reinitialize (e.g. Apache, sendmail)
* controlling pseudo or virtual terminal has been closed
I believe second meaning is more appropriate for offlineimap, and
hence this patch makes SIGHUP to be handled in the same way SIGTERM
and SIGINT are handled.

Fix imapfolder.getmessageinternaldate misparsing the Date:
header from emails due to a bug or surprising behaviour by
email.utils.parsedate. This is because email.utils.parsedate's
return value contains the unadjusted hour value from the string
parsed but does not include information about the time zone in
which it is specified. For example (Python 2.7.3):
$ python -c "import email.utils;
print email.utils.parsedate('Mon, 20 Nov 1995 19:12:08 -0500')"
(1995, 11, 20, 19, 12, 8, 0, 1, -1)
(the -1 is the isdst field); the -0500 time zone is completely
ignored, so e.g. the same input with time "19:12:08 +0300" has
the same result. When passed to time.struct_time as allowed per
the parsedate documentation, this time is interpreted in GMT and
thus deviates from the correct value by the timezone offset
(in this example, -5 hours).
I consider this a bug in email.utils.parsedate: In my opinion,
since the return value of the parsetime doesn't include a timezone,
it should be expressed in terms of UTC rather than in terms of the
time zone from the Date header; the existence of
email.utils.parsedate_tz, to which I've switched, indicates that
maybe the authors were aware of this problem.

Previous commit e7ca5b25cb combined
checks for filtered folders in one place. However, it turns out there
was a reason to have them separate. getfolder() on a non-existent Maildir
fails and there might not be an equivalent local Maildir folder for a
filtered out IMAP folder.
Fix this by first checking if the remote folder should be filtered, and
only then retrieving the local folder (which should exist then).
This bug was found by our test suite!
