Rather than throwing ValueError, we now properly throw OfflineImapError
when selecting a folder in folderincludes. So we also need to catch
OfflineImapErrors here. If they are of severity FOLDER, just ignore the
invalid folder and continue. If the error is more severe, bubble it up.

Remove a level of wrapper abstraction that is not needed. Just use
IMAPserver and be done with it.
We do this by passing in the IMAPRepository() instance rather than a
long list of single paramters to the IMAPServer instanciation. This way
we can retrieve all repository parameters ourselves, rather than passing
a dozen paramters into IMAPServer. Also, this enables us to pass the
repository() object into our WrappedIMAP4() instance, so that it can
query, e.g. the SSL fingerprint configuration.

We simply assert()ed that APPENDing a message returned OK, but in some
cases (e.g. Google chat messages) APPEND might return BAD or NO too. We
should be throwing an OfflineImapError here at MESSAGE level, so that we

details on what went wrong at the end of the sync run.

getselectedfolder was using a cached variable that we were setting in
select(), but sometimes the IMAP4 instance got into the SELECTED state
without explicitely select()ing, it seems, and our variable was unset.
Let us just use the self.mailbox variable that imaplib2 is setting when
select()ing rather than doing our own caching. Also remove the part
where we were setting the cache.
Just access self.state rather than looking up self.state via
self.getstate() every time, it is just an unnecessary layer of
redirection.

In an IMAP run where we did not have to sync anything, I spend nearly a
fulls second in imaputil.debug() without even having debug output
enabled. imapsplit is mainly called by flagsplit() which will also do
debug output, so we get TONS of nearly duplicate debug output in the log
which makes it really hard to analyze.
Cut down the debug logging in imapsplit, we should be debug logging
stuff at a slightly higher level than here anyway.
This one-line change sped up my folder sync (without having to sync
anything) by 0.5 seconds even when debugging is disabled.

Previously, we instanciated an MappedImapFolder, and would cleverly (too
cleverly?) invoke methods on it casting it to an IMAPFolder by calling
methods such as: self._mb.cachemessages(self) where self._MB is the class
IMAPFolder and self and instance of MappedImapFolder. If
e.g. cachemessages() invokes a method uidexists() which exists for
MappedImapFolder, but not directly in IMAPFolder, I am not sure if
Python would at some point attempt to use the method of the wrong class.
Also, this leads to some twisted thinking as our class would in same
cases act as an IMAPFolder and in some cases as an MappedImapFOlder and
it is not always clear if we mean REMOTE UID or LOCAL UID.
This commit simplifies the class, by a)doing away with the complex Mixin
construct and directly inheriting from IMAPFOlder (so we get all the
IMAPFOlder methods that we can inherit). We instantiate self._mb as a
new instance of IMAPFolder which represents the local IMAP using local
UIDs, separating the MappedIMAPFolder construct logically from the
IMAPFolder somewhat.
In the long run, I would like to remove self._mb completely and simply
override any method that needs overriding, but let us take small and
understandable baby steps here.

During a sync run, someone might remove or move IMAP messages. As we
only cache the list of UIDs in the beginning, we might be requesting

the response that we get when we ask for unknown UIDs.
Also, if the server responds with anything else than "OK", (eg. Gmail

We currently do not allow nametrans rules such as
nametrans = lambda foldername: re.sub('^INBOX$', '', foldername)
because we crash with a traceback when running:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=499755
The underlying reason is that we cannot create the "top level" root
directory of the Maildir in the function makefolders(), it will bail
out. John Goerzen intentionally prevented offlineimap from creating the
top-level dir, so that a misconfiguration could not arbitrarily create
folders on the file system. I believe that it should be perfectly
possible to automatically create the root dirctory of the maildir. We
still protect against folder creations at arbitrary places in the file
system though.
This patch cleans up makefolders(), adds documentation, allows to
automatically create rootfolders if needed (using absolute paths) and
adds some robustness in case the folders already exist that we want to
create (rather than simply crapping out).

Folder.savemessage() is supposed to return the new UID that a backend

For some reason, the UIDMappedFolder was not returning anything in
savemessage, despite clearly stating in the code docs that it is
supposed to return a UID. Not sure how long this has already been the
case. This patch fixes the UIDMappedFolder to behave as it should.

Previously we were attempting to save out mails according to
http://www.qmail.org/man/man5/maildir.html in 4 steps:
1 Create a unique filename
2 Do stat(tmp/<filename>). If it found a file, wait 2 sec and go back to 1.
3 Create and write the message to the tmp/<filename>.
4 Link from tmp/* to new/*
(we did step 2 up to 15 times) But as stated by
http://wiki1.dovecot.org/MailboxFormat/Maildir (see section 'Issues with
the specification'), this is a pointless approach, e.g. there are race
issues between stating that the filename does not exist and the actual
moving (when it might exist).
So, we can simplify the steps as suggested in the dovecot wiki and
tighten up our safety at the same time.
One improvement that we do is to open the file, guaranteeing that it did
not exist before in an atomic manner, thus our simplified approach is
really more secure than what we had before.
Also, we throw an OfflineImapError at MESSAGE level when the supposedly
unique filename already exists, so that we can skip this message and
still continue with other messages.
