Using threading._VERBOSE=1 is broken since python 2.6 till at least
python 3.2, (http://bugs.python.org/issue4188) so we can't use it for
our thread debugging.
Remove the usage of threading._VERBOSE, and implement a "light thread
debug log" that for now outputs information when a new thread is being
registered and when it is being unregistered. I am sure we will be able
to add more thread debugging information over the time.
Besides '-d thread' this will re-enable the usage of -d 'all' for the
most verbose debugging of all categories.

When our LocalStatus cache is corrupt, ie e.g. it contains lines not in
the form number:number, we would previously just raise a ValueError
stating things like "too many values". In case we encounter clearly
corrupt LocalStatus cache entries, clearly raise an exception stating
the filename and the line, so that people can attempt to repair it.

This commit enables true 1-way syncing between repositories. This has
often been demanded for backup purposes when you do not want to cause
accidental modifications of your backup that would be propagated to the
other side.
This has been implemented by allowing to configure a Repository as
'readonly' to forbid any modification on it.
'readonly' applies to all the type of repositories.

in accounts.sync() we would holdordropconnections() after each sync. But
depending on the repository configuration that might imply that
offlineimap tries to keep the same connections. But when a sync failed,
e.g. after a user had his computer suspended, it might be that our
connections that we have are worthless. So definitely drop them after a
failed sync.

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.

For each folder we were making a second IMAP request asking for the
latest UID and compared that with the highest UID in our
statusfolder. This catched the case that 1 mail has been deleted by
someone else and another one has arrived since we checked, so that the
total number of mails appears to not have changed.
We don't capture anymore this case in the quickchanged() case.
It improves my performance from 8 to about 7.5 seconds per check (with lots of
variation) and we would benefit even more in the IMAP<->IMAP case as we do one
additional IMAP lookup per folder on each side then.
Do cleanups on whitespaces while in this file.

We are calling getmessagelist() internally a lot, e.g. just to check if
a UID exists (from uidexist()). This is a very expensive operation in
the UIDMapped case, as we reconstruct the whole messagelist dict every
single time, involving lots of copying etc.
So we provide more efficient implementations for the uidexists()
getmessageuidlist() and getmessagecount() functions that are fast in the
UIDMapped case. This should solve the performance regression that was
recently observed in the Mapped UID case.

When uploading a new message to Gmail we need to find out the UID it
assigned it, but Gmail does not advertize the UIDPLUS extension (in all
cases) and it fails to find the email that we just uploaded when
searching for it. This prevented us effectively from uploading to
gmail.
See analysis in
http://lists.alioth.debian.org/pipermail/offlineimap-project/2011-March/001449.html
for details on what is going wrong.
This patch increases compatability with Gmail by checking for APPENDUID
responses to an APPEND action even if the server did not claim to
support it. This restores the capability to upload messages to the
*broken* Gmail IMAP implementation.
