This suppressing the warning generated when running offlineimap on
python2 with -3 switch:
offlineimap/folder/Base.py:29: DeprecationWarning: Overriding __eq__
blocks inheritance of __hash__ in 3.x
Since this object is mutable it should not be hashable.
From Python documentation[1]:
A class that overrides __eq__() and does not define __hash__() will
have its __hash__() implicitly set to None.
Therefore old behaviour is preserved.

OfflineIMAP frequently delivers mail files to the Maildir consisting exclusively
of a single ASCII digit in IDLE mode. IMAPFolder.getmessage expects 'data' to be
of the form
[(fetch-info, message-body)]
However, the imapobj.uid call in getmessage returns a list of *all* pending
untagged FETCH responses. If any message flags were changed in the selected
IMAP folder since the last command (by another client or another thread in
OfflineIMAP itself), the IMAP server will issue unsolicited FETCH responses
indicating these flag changes (RFC3501, section 7). When this happens, 'data'
will look like, for example
['1231 (FLAGS (\\Seen) UID 5300)',
'1238 (FLAGS (\\Seen) UID 5318)',
('1242 (UID 5325 BODY[] {7976}', message-body)]
Unfortunately, getmessage retrieves the message body as data[0][1], which in
this example is just the string "2", and this is what gets stored in the mail
file.
Multi-threaded OfflineIMAP with IDLE or holdconnectionopen is particularly
susceptible to this problem because flag changes synced back to the IMAP server
on one thread will appear as unsolicited FETCH responses on another thread if it
happens to have the same folder selected. This can also happen without IDLE or
holdconnectionopen or even in single-threaded OfflineIMAP with concurrent access
from other IMAP clients (webmail clients, etc.), though the window for the bug
is much smaller.
Ideally, either imaplib2 or getmessage would parse the fetch responses to find
the response for the requested UID. However, since IMAP only specifies
unilateral FETCH responses for flag changes, it's almost certainly safe to
simply find the element of 'data' that is a tuple (perhaps aborting if there is
more than one tuple) and use that.

Commit 6b28071b0f makes the check once nametrans is applied. This is wrong
because separators are valid characters in names returned by nametrans. E.g:
"Sent" -> "[Gmail]/Sent"
Make the check against the raw name of the folder, instead.

1. There is one database per folder and sqlite requires to serialize the
writings. Instead of locking at LocalStatusSQLiteFolder object level, introduce
a new DatabaseFileLock object which is shared across threads. This fixes the
concurrent writes issues that some users might experience by duplications or
flags restored to the previous state.
2. Close the database only when we are sure no other threads will use the
connection on a *per-file* basis. Previous fix 677afb8d8f is wrong
because the same lock is shared for all the databases.

It's required to have more than one connection to the database for the
maxconnections configuration option to work with threads. However,
connection.close() is closing all the connections. Only close the connection
