e023f190b0 folder/Maildir: Store only relative filename components
MaildirFolder.messagelist[*]['filename'] was storing the absolute file
paths for all stored emails. While this is convenient, it wastes much
space, as the folder prefix is always the same and it is known to the
MaildirFolder. Just 40 chars in a folder with 100k mails waste >4MB of
space. Adapt the few locations where we need the full path to construct
it dynamically.

c1c200a487 folder/Maildir: cache getfullname() value
We use getfullname() very often (thousands to millions), yet we
dynamically calculate the very same value over and over. Optimize this

520e39d355 Update imaplib2 to 2.24
In some cases we had offlineimap trying to delete emails that shouldn't
be deleted. E.g. https://bugzilla.redhat.com/show_bug.cgi?id=708898.

It turns out that imaplib2 does not like FETCH responses that are
interrupted by other unsolicited server responses, e.g.

* OK Searched 43% of the mailbox, ETA 0:12\r\n

Bump imaplib2 to a version that can cope with these (legal) responses by
the IMAP server.

e8b633b884 folder/IMAP: Remove buggy duplicate assignment
we do:
  for msgid in imapdata:
      maxmsgid = max(long(msgid), maxmsgid)
and then basically immediately:
   maxmsgid = long(imapdata[0])

throwing away the first assignment although the first method of
assigning is the correct one. The second had been forgotten to be
removed when we introduced the above iteration. This bug would fix a
regression with those broken ZIMBRA servers that send multiple EXISTS
replies.

b20f5192fb Allow to specify remote hostname even for the Gmail case
Previously we hard-coded the imap server name in the case of Gmail
repositories, but often we need a different host name. So, allow people
to specify the hostname via the regular "remotehosteval" and
"remotehost" settings, and only falling back to imap.gmail.com when
nothing has been specified.

Cache the hostname, so we don't evaluate the whole thing each time we
query the host name.

Make the remotehosteval processing more robust, by catching any
Exceptions that occur, and throw a OfflineImapError, that explains where
exactly the error had occured. You can test this, e.g. by setting
remotehosteval to 1/"n" or some other invalid expression.

The whole IMAP.gethost() function has been documented code wise while
going through.

1754bf4110 Allow to create the root MailDir directory
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).

to what went wrong using an "assert" message, although the correct thing

3dc9fc519a Throw errors on connection refused and on non-standard SSL ports
We were "crashing" with tracebacks when we could not connect to a host,
(e.g. because no service was on the port) and we were getting mysterious
SSL tracebacks when someone tried to connect via SSL to a non-ssl port.

In these cases, we will now throw an nice error message. On python<2.6
where no ssl module exists, we simply won't throw those errors.

694e5772da threadutil: remove broken os.exit()
We are missing the import of 'os' python module since commit d839be3c61
(Sat Apr 16 20:33:35 2005 +0100) which was when John switched from SVN to Git.

Happily, it help us today: we still had no feedback for this missing import,
6 years later.  So, we can remove the os.exit() call safely.

That beeing said, we still don't know if the above sys.exit() was ever touched.
My guess is that it never was. Keep this (hopefully) commented statement to
ensure the thread terminate and not play too much with the Murphy's law. :-)

c70a621709 Limit msg body length in debug output
We were outputting full message bodies to the debug log (often stderr),
and then again (as they go over the imaplib2 wire, imaplib logs
everything too). Not only is quite a privacy issue when sending in debug
logs but it can also freeze a console for quite some time. Plus it
bloats debug logs A LOT.

Only output the first and last 100 bytes of each message body to the
debug log (we still get the full body from imaplib2 logging). This
limits privacy issues when handing the log to someone else, but usually
still contains all the interesting bits that we want to see in a log.

89619838b0 Remove weird SigListener class
The SigListener class was used to queue folders that we need to sync and
to receive "resync" and "abort" signals. It was undocumented and weird
and we had to pass "siglisteners" through the whole program.

Simply do away with it, and make 2 functions in the Account() class:
set_abort_event and get_abort_event which can be used to set and check
for such signals. This way we do not need to pass siglisteners all over
the place. Tested Blinkenlights and TTYUI uis to make sure that SIGUSR1
and SIGUSR2 actually still work.

Document those signals in MANUAL.rst. They were completly undocumented.

This simplifies the code and interdependencies by passing less stuff
around. Removes an undocumented and weirdly named class.
