23f96ba880 Encode utf-8 argument for md5 function
Python3 accepts binary input for md5 function.

This patch is known to break setups using folder names not strictly conforming
the IMAP UTF-7 encoding. We always made it clear that such setup is unsupported
and might be broken at some point in time. See documentation about
'decodefoldernames' in the provided configuration file. This is why this patch
is considered introducing no regression for this use case.

Patches to support both Python 3 and Python 2 by re-encoding the MD5 in the
filenames are welcome. This likely requires a new CLI option to allow
backporting the feature for users downgrading or changing of Python environment.

05c75e8c8d sqlite: open database when we use it rather than at instantiation time
We currently close the database as soon as possible while we handle the status
backend but this is still too early because autorefresh induces looping on this
code block.

Instead of delaying the closing outside of the loop, it's easier to delay the
opening as late as possible (inside the loop). The downside is that the database
is opened/closed more than once when autorefresh is enabled. The good news is
that this make the code much easier.

Fixes regression introduces by 6fb5700.

6b8ee4a183 Handle maxage for davmail correctly
"imapobj.search" returns a list with one string element of numbers
separated by one whitespace character for regular box (GMail, AOL...).
['1 2 3 4 5 6 7 8 9 10 11 12']
But if we would like to sync from Davmail it would return a list of
numbers.
['1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12'].

The code "return res_data[0].split()" in the first case will return what
we already have when using Davmail, hence only one email will be
fetched.  But if only the first sync would be with maxage the emails
will be removed, because offlineimap will think that they were removed
by us.

The patch distinguishes between syncing with Davmail and regular box and
applies split on the first element only when it finds whitespace
character.  It also handles the case when the first element is empty on
first sync.

Closes #327

c84d23b656 Identify and fix messages with FMD5 inconsistencies
Introduce the '--migrate-fmd5-using-nametrans' option which migrates the
FMD5 hashes from versions prior to 6.3.5.

It seems that commit 'Apply nametrans to all Foldertypes' (6b2ec956cf)
introduced a regression because it changed the FMD5 part of the filename
calculated by OfflineIMAP. Thus, OfflineIMAP believes that the messages
has been removed and adds them back.

3b30c4aa93 add new config option filename_use_mail_timestamp
If this value is true, use (if possible) a timestamp based on message
Date or Delivery-date headers. The current system time is used
otherwise.

filename_use_mail_timestamp and utime_from_header are now completely
separated option that do not interfere one with other.

To handle this feature in a multithread context we use a hash to count
the number of mail with the same timestamp. This method is more accurate
than using the old lasttime and timeseq variables.

8096f6cd5b maxage: fix timezone issues, remove IMAP-IMAP support, add startdate option
1. When using maxage, local and remote messagelists are supposed to only
contain messages from at most maxage days ago. But local and remote used
different timezones to calculate what "maxage days ago" means, resulting
in removals on one side. Now, we ask the local folder for maxage days'
worth of mail, find the lowest UID, and then ask the remote folder for
all UID's starting with that lowest one.

2. maxage was fundamentally wrong in the IMAP-IMAP case: it assumed that
remote messages have UIDs in the same order as their local counterparts,
which could be false, e.g. when messages are copied in quick succession.
So, remove support for maxage in the IMAP-IMAP case.

3. Add startdate option for IMAP-IMAP syncs: use messages from the given
repository starting at startdate, and all messages from the other
repository. In the first sync, the other repository must be empty.

4. Allow maxage to be specified either as number of days to sync (as
previously) or as a fixed date.

25513e9038 fix: don't loose local mails because of maxage
Suppose messages A and B were delivered to the remote folder at
"maxage + 1" days ago.

A was downloaded to the local folder "maxage + 1" days ago, but B was only
downloaded "maxage - 1" days ago (contrived scenario to illustrate the two
things that could happen). The behavior was that B gets deleted from the local
folder, but A did not. The expected behavior is that neither is deleted.

Starting where Base.py: __syncmessagesto_delete(self, dstfolder, statusfolder)
is called where:
 - self is the remote folder
and
 - dstfolder is the local folder.

It defines deletelist to be the list of messages in the status folder
messagelist that aren't in the remote folder messagelist with

  not self.uidexists(uid)

A and B are both in the status folder. They're also both *NOT* in the remote
folder messagelist: this list is formed in IMAP.py: cachemessagelist(), which
calls _msgs_to_fetch(), which only asks the IMAP server for messages that are
"< maxage" days old.

Back to Base.py __syncmessagesto_delete(), look at the call
folder.deletemessages(deletelist), where folder is the local folder. This ends
up calling Maildir.py deletemessage() for each message on the deletelist. But we
see that this methods returns (instead of deleting anything) if the message is
in the local folder's messagelist. This messagelist was created by Maildir.py's
cachemessagelist(), which calls _scanfolder(), which tries to exclude messages
based on maxage. So at this point, we *WANT* A and B to be excluded -- then they
will be spared from deletion. This maxage check calls _iswithinmaxage(), and
actually does the date comparison based on the time found at the beginning of
the message's filename. These filenames were originally created in Maildir.py's
new_message_filename(), which calls _gettimeseq() to get the current time (i.e.
the time of retrieval).

Upshot: A's filename has an older timestamp than B's filename. A is excluded
from the local folder messagelist in _scanfolder(), hence spared from deletion
in deletemessage(); B is not excluded, and is deleted.

This patch does not address the timezone issue. As for the IMAP/timezone issue,
a similar issue is discussed in the thunderbird bug tracker here:

https://bugzilla.mozilla.org/show_bug.cgi?id=886534

In the end, they're solving a different problem, but they agree that
there is really no reliable way of guessing the IMAP server's internal
timezone.
