We simply lock OfflineImap the same global way that we have always done
in addition to the previously implemented per-account lock. We can keep
both systems in parallel and then after a few stable releases, drop the
old-style global lock. by reverting this patch

Previously, we were simply locking offlineimap whenever it was
running. Howver there is no reason why we shouldn't be able to invoke it
in parallel, e.g. to synchronize several accounts in one offlineimap
each.
This patch implements the locking per-account, so that it is possible to
sync different accounts at the same time. If in refresh mode, we will
attempt to loop three times before giving up.

open() and os.open() lead to different file permissions by default, and
while we have not changed the os.open that had been used, some code
changes led to these permissions slipping through. Fix this by setting

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.

The readonly feature was introduced to safeguard repositories from
accidental modifications. Unfortunately, my patch treated the readonly
setting as a string and not as a boolean, so if *anything* was set in
the configuration file as 'readonly', this value evaluated to True
Fortunately this was safe, we never treated a repository that we wanted
read-only as read-write. We always treated them readonly if something
was configured as "readonly=..." even if that was False.
The fix is simply to use getconfboolean() rather than getconf() which
checks for True/False/On/Off/yes/no/1/0 and hands back the correct boolean.

If a folder is empty, most servers will return EXISTS 0 and imaplib2

no EXISTS response was given by the server at all.
Attempting to fetch the UIDs of 0 emails which leads to
various error messages (One server responds with "NO No matching
messages", Gmail seems to say "BAD Bad message sequence 1:*" for some
(although it is working fine for me with Gmail, so it might behave
different for different people).
