The support for the realdelete configuration option was removed because this
could lead to data loss.

The retry loop would release connection that would get
re-released upon ``finally`` clause. In consequence, an
exception would be cast.

1. When using maxage, local and remote messagelists are supposed to only
contain messages from at most maxage days ago. But local and remote used
different timezones to calculate what "maxage days ago" means, resulting
in removals on one side. Now, we ask the local folder for maxage days'
worth of mail, find the lowest UID, and then ask the remote folder for
all UID's starting with that lowest one.
2. maxage was fundamentally wrong in the IMAP-IMAP case: it assumed that
remote messages have UIDs in the same order as their local counterparts,
which could be false, e.g. when messages are copied in quick succession.
So, remove support for maxage in the IMAP-IMAP case.
3. Add startdate option for IMAP-IMAP syncs: use messages from the given
repository starting at startdate, and all messages from the other
repository. In the first sync, the other repository must be empty.
4. Allow maxage to be specified either as number of days to sync (as
previously) or as a fixed date.

We usually mutate some exceptions to OfflineImapError() and it is
a whole lot better if such exception will show up with the original
traceback, so all valid occurrences of such mutations were transformed
to the 3-tuple form of "raise". Had also added coding guidelines
document where this re-raise strategy is documented.

This fixes a bug in which a message ended up with multiple gmail labels
header (X-Keywords or so). Fix fix it by removing all labels headers
before adding the updated one.

There should be just one header storing gmail labels, but due to a bug,
multiple X-Keywords (or equivalent) headers may be found on the local
messages.
Now we, when extracting the labels from a message, we read all label
headers, instead of just the first one.
This has the consequence that some old labels stored locally in a second
X-Keywords (or third...) header, which effectively was rendered
invisible to offlineimap until now, may pop back up again and be pushed
to gmail. No labels will be removed by the changes in this commit,
though.

Create initializer function that puts default values to all fields
of message list item. Fix all code that directly assigns some hash
to the elements of messagelist: for direct assignments only initializer
is now permitted, all other modification are done in-place.

For servers without UIDPLUS we are inserting additional header
just after transformation '\n' -> CRLF was done. addmessageheaders()
was written to work with just '\n' as the separator, so X-OfflineIMAP
header wasn't preceeded by the CRLF, but just by '\n'.

* Implements Status Folder format v2, with a mechanism to upgrade an
old statusfolder.
* Do not warn about Gmail and GmailMaildir needing sqlite backend
anymore.
* Clean repository.LocalStatus reusing some code from
folder.LocalStatus.
* Change field separator in the plaintext file from ':' to '|'. Now
the local status stores gmail labels. If they contain field
separator character (formerly ':'), they get messed up. The new
character '|' is less likely to appear in a label.

Format headers X-Label and Keywords as a space separated list and all
other ones as comma-separated entities. This makes OfflineIMAP label
handling to be compatible with some user agents that recognise these
headers.

When synclabels config flag is set to "yes" for the GMail repo,
offlineimap fetches the message labels along with the messages, and
embeds them into the body under the header X-Keywords (or whatever
'labelsheader' was set to), as a comma separated list.
It also adds an extra pass to savemessageto, that performs label
synchronization on existing messages from GMail to local, the same way
it is done with flags.
We also introduce GmailMaildir repository that adds functionality to
change message labels. It keeps track of messages modification time,
so one can quickly detect when the labels may have changed.

It can lead to potential dataloss (see recent commit log where I added a
scary warning about it to offlineimap.conf).

transposed (aka visiblename) of a folder itself just fine. There is no
need to pass it in as an separate parameter.

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.

As all Folders share these parameters, we can safely handle them in
BaseFolder. This makes sense, as BaseFolder has a getname() function
that returns self.name but nothing actually set self.name.
It also saves a few lines of code.

This function was badly named and completely undocumented. Rework it to
avoid copying the full UID list using an iterator. Make it possible to
hand it a list of UIDs as strings rather than implicitely relying on the
fact that they are numeric already. Document the code.
The behavior off the function itself remained otherwise unchanged.

As this is essentially what it is, a set of values. This allows as
to do set arithmetics to see, e.g. the intersection of 2 flag sets
rather than clunkily having to do:
for flag in newflags:
if flag not in oldflags:
oldflags.append(flag)
Also some more code documenting.

This function was overridden as the IMAP version apparently had been
using imapobj.myrights() at some point in time, which was not
implemented in the Gmail version. However, IMAP is not using myrights()
anymore, and as that is an extension that needs to be advertised in
CAPABILITIES we should not unconditionally use it anyway.
So remove the function that is identical to it's ancestor's
function.

Code was broken, as these backends import UIBase (which had been moved).
However, they don't use it, so we can just delete the import.

Bug report received in Debian. User is having occasional trouble with Gmail
driver crashing, indicates problem may have started after switching to Gmail.
Gmail driver merged to tree in 81b86fb74 on 2008-01-03 and recently released
in beta tarballs.
BT shows:

imap: imapsplit() called with input: None
imap: imapsplit() got a non-string input; working around.
looking at code for Gmail.py processmessagesflags, comments from Ricardo
indicate it was copied from the same function in folder/IMAP.py.
However, folder/IMAP.py has checks for this, added 2002-07-12 in
5342dacc & 817a10ce. Suspect that Gmail author believed those checks
superfluous for Gmail.
Copied checks from folder/IMAP.py to folder/Gmail.py.
New repository/folder classes to support "real deletion" of messages
thorugh Gmail's IMAP interface: to really delete a message in Gmail,
one has to move it to the Trash folder, rather than EXPUNGE it.
