Make sure that when a connection is dropped during append, we really
discard the broken connection and get a new one, retrying. We retry
indefinitely on the specific abort() Exception, as this is what imaplib2
suggests us to do.

If a connection is broken, we want to have it really dropped and not be
reused. So far, we are checking the .Terminate attribute for this, but
according to the imaplib2 author, it is only set on normal shutdown and
it is an undocumented attribute whose meaning could change any time.
This patch introduces the parameter drop_conn which allows to tell
releaseconnection() that we really want to connection being dropped from
the pool of available connections and properly destroy it.

If a connection is dropped for some reason while fetching a message, the
imapobj.uid command throws an imapbj.abort() Exception which means we are
supposed to retry. Implement a fail loop that drops the connection, gets a
new one and attempts the command another time.
Remove obsolete comment that we need to catch nonexisting messages. We do

Imapserver.acquireconnection will succeed even whent the server connection
has been terminated and the first IMAP operation will throw an exception.
Often this is the folder SELECT operation (e.g. after an idle timeout), as

OfflineImapError with severity FOLDER_RETRY to notify consumers that they
are supposed to retry.

Name parameter that hands us a Status Repository 'status_repo' and not

a) make it clear that we pass in a repository and not folder
instances. That was very confusing before.
b) We were always only using one 'copyfolders' item anyway, so let us
not make it a list.

SafeConfigParser is very similar to the currently used ConfigParser but
it supports interpolation. This means values can contain format strings
which refer to other values in the same section, or values in a special
DEFAULT section. For example:
[My Section]
foodir: %(dir)s/whatever
dir=frob
would resolve the %(dir)s to the value of dir (frob in this case). All reference expansions are done on demand.

imaplib renamed self.sslobj to self.sock and our overriden open()
functions were failing for that reason when updating imaplib2 to
v2.28. It turns out that all of our custom initializations are being
done by stock imaplib2 now anyway, so there is no need to override them
anymore. This lets us simplify the code we have to worry about.
Move the verifycert() function to the imapserver.py file, it is now a
callback function that is being handed to imaplib from there, so it
makes sense to also define it in our imapserver function...
(this also lets us easily make use of the verifycert function in the
starttls case in the future)

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.

Remove a level of wrapper abstraction that is not needed. Just use

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
