Remove the old global locking system. We lock only the accounts that we
currently sync, so you can invoke OfflineImap multiple times now as long
as you sync different accounts. This system is compatible with all
releases >= 6.4.0, so don't run older releases simultanous to this one.
This mostly reverts commit 0d95651417,
disabling the old global lock system that we had in parallel to the new one.

This change looks harmless, but it fixes a severe bugfix, potentially
leading to data loss! It fixes the "on n new uploads, it will redownload
n-1, n-2, n-3,... messages during the next syncs" condition, and this is
what happens:
If there are more than one Mails to upload to a server, we do that by
repeatedly invoking folder.IMAP.savemessage(). If the server supports
the UIDPLUS extension we query the resulting UID by doing a:
imapobj._get_untagged_response('APPENDUID', True)
and that is exactly the problem. The "True" part causes the reply to
remain in the "response stack" of the imaplib2 library. When we do
the same call on a subsequent message and the connection is still on the
same folder, we will get the same UID response back (imaplib2 only looks
for the first matching response and returns that). The only time we
clear the response stack, is when the IMAP connection SELECTS a
different folder.
This means that when we upload 10 messages, the IMAP server gives us
always the same UID (that of the first one) back. And trying to write
out 10 different messages with the same UID will confuse OfflineIMAP.
This is the reason why we saw the ongoing UPLOADING/DOWNLOADING behavior
that people reported. And this is the reason why we saw the
inconsistency in the UID mapping in the IMAP<->IMAP case.
I urge everyone to upgrade ASAP. Sorry for that, I don't know why the
problem only became prevalent in the recent few releases as this code
has been there for quite a while.

Previously, assigning a new UID to a mapped IMAP or Maildir repository
was done by loading the "local" item, saving it under a new UID and
deleting the old one. This involved lots of disk activity for nothing
more than an effective file rename in Maildirs, and lots of network
usage in the MappedUID cases.
We do this on every upload from a local to a remote item, so that can
potentially be quite expensive. This patch lets backends that support it
(Maildir, MappedUID) efficiently rename the file rather than having to
read the mail content, write it out as a new file and delete the old
file. This speeds up uploads from Maildir and the MappedUID server.

If someone had a custom :2,a flag, adding a new flag would lead to the
invalid maildir filename ...a:2,... due to regex deficiencies not coping
with this. Fix this so we alway produce valid maildir names.
Note that custom flags are still problematic: as the syncing to the
remote IMAP server will fail, the next sync will assume that they have
been removed from the remote IMAP side and they will be removed from the
local Maildir then. We will need to think about how to handle this. At
least, with this patch we won't lose standard flags and won't produce
invalid maildir names.
Signed-off-by: Sebastian Spaeth <Sebastian@SSpaeth.de>
The regex for catching Maildir message flags was
self.infosep + '.*2,([A-Z]+)' (infosep being ':').

When a new remote folder was detected, we tried to create the folder
locally on the Maildir and called repository.forgetfolders() to force a
new scanning of the Maildir. However, that implementation used the
inherited base function that did nothing. We simply needed to implement
forgetfolders() to set self.folder=None, so we would force a new read in
of the updated local folder structure.

1) Rename the unintuitive repository.syncfoldersto() to

2) We were checking if the local repository is readonly and then turning
off any folder creation. But as we can create folders on a remote

a folder on the repository that is marked readonly=True.
This still does not do away with the error message that one currently
gets on missing local folders.

Dave identified a case where our new dropped connection handling did
not work out correctly: we use the retry_left variable to signify
success (0=success if no exception occured).
However, we were decrementing the variable AFTER all the exception
checks, so if there was one due to a dropped connection, it
could well be that we 1) did not raise an exception (because we want to
retry), and 2) then DECREMENTED retry_left, which indicated "all is
well, no need to retry".
The code then continued to check() the append, which failed with the
above message (because we obtained a new connection which had not even
selected the current folder and we were still in mode AUTH). The fix is
of course, to fix our logic: Decrement retry_left first, THEN decide
whether to raise() (retry_left==0) or retry (retry_left>0) which would
then correctly attempt another loop. I am sorry for this newbie type of
logic error. The retry count loop was too hastily slipped in, it seems.
