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

Sometimes it might happen that you put wrong date and you except emails
to be fetched, but they are not and you do not have an idea why.

By raising exception the user will see a proper message telling that he
used the wrong date for maxage/startdate property.

If someone wants to set a future date intentionally might as well sync
in the future.

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.

c094304f93 make savemessagelabels honor utime_from_header
Previously, syncing labels on a message always resulted in updating the
file modification time, even with utime_from_headers=true

This patch restores the file mtime to the previous value when
utime_from_headers=true, preventing a label synchronization from
breaking the promise that the file mtimes coincide with the header 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.

fc4c7549d6 Do not ignore gmail labels if header appears multiple times
There should be just one header storing gmail labels, but due to a bug,
multiple X-Keywords (or equivalent) headers may be found on the local
messages.

Now we, when extracting the labels from a message, we read all label
headers, instead of just the first one.

This has the consequence that some old labels stored locally in a second
X-Keywords (or third...) header, which effectively was rendered
invisible to offlineimap until now, may pop back up again and be pushed
to gmail. No labels will be removed by the changes in this commit,
though.

1690e5f74e Copymessageto should not be private since we override it
private methods prevent them from being overriden on derived classes. In
GmailFolder we need to override copymessageto, so it can't be private.

Before this commit, copymessageto was made private in Base but not in
GmailFolder. The end result was that labels were not set when copying
the message content, and always needed to be set on the label copying
pass.

1b954c3b4c Add ability to migrate status data across backends
If when we request a LocalStatus folder, the folder has to be created,
we look whether the other backend has data, and if it does we migrate
it to the new backend.

The old backend data is left untouched, so that if you change back say
from sqlite to plaintext, the older data is still there.  That should
not lead to data loss, only a slower sync while the status folder gets
updated.

214137eb7b Improvements to the SQlite-based local status folder
* Do not inherit LocalStatusSQLiteFolder class from the plaintext
    one.

  * Use some functions already in BaseFolder in both, plaintext and
    sqlite classes.

  * Add a saveall method. The idea is that saveall dumps the entire
    messagelist to disk, while save only commits the uncommited
    changes. Right now, save is noop for sqlite, and equivalent to
    saveall for plaintext, but it enables to be more clever on when we
    commit to disk in the future.

  * Clean repository.LocalStatus reusing some code from

  * Change field separator in the plaintext file from ':' to '|'. Now
    the local status stores gmail labels. If they contain field
    separator character (formerly ':'), they get messed up. The new
    character '|' is less likely to appear in a label.

0e4afa9132 Make GmailFolder sync GMail labels
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.

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.

5c842c01bd Fix deadlock for IMAP folder synced in singlethreaded mode
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.
