9453e1d955 Fix getuidvalidity crash (UIDVALIDITY returning None)
Rename getuidvalidity -> get_uidvalidity and cache the IMAP result.

1) Start modernizing our function names using more underscores
2) IMAPs implementation of get_uidvalidity was removing the UIDVALIDITY result
   from the imaplib2 result stack, so subsequent calls would return "None".
   As various functions can invoke this, this led to some errors that we
   avoid by caching the current UIDVALIDITY value in the Folder instance.

There are more simplifications and improvements to be made.

de537dc09c Implement change_message_uid
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.

0ccf06d5e6 Implement clean CTRL-C termination
Previously, we would simply bail out in an ugly way, potentially leaving
temporary files around etc, or while writing status files. Hand SIGINT
and SIGTERM as an event to the Account class, and make that bail out
cleanly at predefined points. Stopping on ctrl-c can take a few seconds
(it will e.g. finish to transfer the ongoing message), but it will shut
down cleanly.

e30ae53b2a Folder: Force top-level folder visiblename to ''
nametrans rules can lead to different visiblename names for the
top-level directory, specifically both '.' and '' (the latter was
recently introduced). However, we need to be able to compare folder
names to see if we need to create a new directory or whether a directory
already exists, so we need to be able to compare a repositories
visiblename (=transposed via nametrans rule) with another folder.

To make the top-level directory comparison happen, we enforce a
top-level name of '', so that comparisons work.

410e2d35e9 Set accountname in BaseFolder, and don't pass it in initialization
We passed in the accountname to all derivatives of BaseFolder, such as
IMAPFolder(...,repository,...,accountname), although it is perfectly
possible to get the accountname from the Repository(). So remove this
unneeded parameter. Each backend had to define getaccountname() (although
the function is hardly used and most accessed .accountname directly).

On the other hand BaseFolder was using getaccountname but it never defined
the function. So make the sane thing, remove all definitions from backends
and define accountname() once in Basefolder. It was made a property and not
just a (public) attribute, so it will show up in our developer
documentation as public API.

9f23fea74e Fix error handling in folder.Base.copymessageto()
This is a bug fix on several levels. 1) We were lacking the import of
OfflineImapError. 2) OfflineImap.ERROR.MESSAGE was misspelled as ERROR.Message.
3) COntinuing with the next message only worked in single-thread mode
(using debug) and not in multi-thread mode. The reason is that we were
invoking a new thread and catching Exceptions in the main thread. But
python immediately aborts if an Exception bubbles up to a thread start.
This was fixed by catching exceptions directly in copymessageto() which
is the new thread, rather than catching them in the main thread.

e20d8b9679 Remove upload neguid pass from sync logic
In order to optimize performance, we fold the 1st and 2nd pass of our
sync strategy into one. They were essentially doing the same thing:
uploading a message to the other side. The only difference was that in
one case we have a negative UID locally, and in the other case, we have
a positive one already.

This saves some time, as we don't have to run through that function on
IMAP servers anyway (they always have positive UIDs), and 2nd were we
stalling further copying until phase 1 was finished. So uploading a
single new message would prevent us from starting to copy existing
regular messages.

3eee821382 Simplify the syncing strategy a bit
The previous syncing strategy was doing more than we needed to and was a
bit underdocumented. This is an attempt to clean it up.

1) Do away with the previous different code paths depending on
whether there is a LocalStatus file or not (the isnewfolder() test). We
always use the same strategy now, which makes the strategy easier to
understand. This strategy is simply:

a) Sync remote to local folder first
b) Sync local to remote

Where each sync implies a 4 pass strategy which does basically the same
as before (explained below).

2) Don't delete messages on LOCAL which don't exist on REMOTE right at
the beginning anymore. This prevented us e.g. from keeping local
messages rather than redownloading everything once LocalStatus got
corrupted or deleted. This surprised many who put in an existing local
maildir and expected it to be synced to the remote place. Instead, the
local maildir was deleted. This is a data loss that actually occured to
people!

3) No need to separately sync the statusfolder, we update that one
simultanously with the destfolders...

3) Simplified the sync function API by only taking one destdir rather
than a list of destdirs, we never used more anyway. This makes the code
easier to read.

4) Added plenty of code comments while I was going through to make sure
the strategy is easy to understand.
-----------------------------------------

 Pass1: Transfer new local messages
        Upload msg with negative/no UIDs to dstfolder. dstfolder should
        assign that message a new UID. Update statusfolder.

 Pass2: Copy existing messages
        Copy messages in self, but not statusfolder to dstfolder if not
        already in dstfolder. Update statusfolder.

 Pass3: Remove deleted messages
        Get all UIDS in statusfolder but not self. These are messages
        that we have locally deleted. Delete those from dstfolder and
        statusfolder.

 Pass4: Synchronize flag changes
        Compare flags in self with those in statusfolder. If msg has a
        valid UID and exists on dstfolder (has not e.g.  been deleted
        there), sync the flag change to dstfolder and statusfolder.

The user visible implications of this change should be unnoticable
except in one situation:
 Blowing away LocalStatus will not require you to redownload ALL of
 your mails if you still have the local Maildir. It will simply recreate
 LocalStatus.

30344587d9 Patch for error handling / separation of accounts etc.
Dear All,
I have made the attached patch to try and make offlineimap a bit more
stable in challenging situations.  It's extremely useful in slow
connection environments - but sometimes if one account had the wrong
password or the connection went down then unfortunately the whole
program would crash.

I have tested this on our connection and tried throwing at it just about
every situation - connection, up down, up, down again, change password,
error whilst copying one message, etc.  I have been running this patch
for the last 5 days or so syncing 6 accounts at the moment...  It seems
to work and stay alive nicely (even if your connection does not)...

Hope that this can go in for the next release... Please let me know if
anyone notices any problems with this...

Regards,

-Mike

Subject: [PATCH] This patch attempts to introduce a little more error handling - e.g.
 if one account has an error because of a changed password or something
 that should not affect the other accounts.

Specifically:
If one sync run has an issue this is in a try-except clause - if it
has an auto refresh period the thread will sleep and try again - this
could be quite useful in the event of the connection going down for a
little while, changed password etc.

If one folder cannot be created an error message will be displayed through
the UI and the program will continue (e.g. permission denied to create a folder)

If one message does not want to copy for whatever resaon an error message
will be displayed through the UI and at least the other messages will
be copied

If one folder run has an exception then the others will still run

03488ba81b Sync INTERNALDATE <-> mtime
The attached patch adds syncing the INTERNALDATE of IMAP folders with
the mtime of messages in maildir folders.
I want this to happen, because I'm running a dovecot over the maildirs
synced by offlineimap, and that uses the mtime as the INTERNALDATE.
When using mutt to view messages I generally sort based on the received
date, which for IMAP folders is the INTERNALDATE.

Since this is the first real coding I've done in Python the patch may
need to be cleaned up some, but it's working pretty well for me.  I've
added new messages to each side, and the received date has been
preserved going both ways.

0841e03a4c [319117] Unroll loop to speed performance on large folders
From: "Nikita V. Youshchenko"
I trued to use offlineimap and found that while being quite fast on
small folders, it takes up to several minutes (of 100% busy CPU and
almost no network traffic) to sync a folder with 2000+ messages.

While looking into the code, I found why this happens.
In folder/Base.py, in method BaseFolder.syncmessagesto_copy(),
dest.getmessagelist() is called inside a loop, while being a loop
invariant. Similar thing happens in BaseFolder.syncmessagesto_delete()
for self.getmessagelist().
This causes quadratic complexity over folder size.

Moving these calls out of loops make large folder sync fast (several
