038a433f69 backport: sqlite: properly serialize operations on the databases
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.

1410a391bc avoid removing of data when user removed a maildir
When a maildir is removed it must be considered new for the sync. However, the
local cache of the folder remains. This means the sync of the folder removes all
the missing emails.

Avoid loosing of data for users not aware of the local cache by removing any
pre-existing status cache of a folder when we actually want to create the
database.

Improve style.

3f70d9ef37 sqlite: open database when we use it rather than at instantiation time
Backported from 8e995a69bfa003ab822b55731429d84b3bc5626f.

We currently close the database as soon as possible while we handle the status
backend but this is still too early because autorefresh induces looping on this
code block.

Instead of delaying the closing outside of the loop, it's easier to delay the
opening as late as possible (inside the loop). The downside is that the database
is opened/closed more than once when autorefresh is enabled. The good news is
that this make the code much easier.

Fixes regression introduces by 6fb5700.

acc9c3cf49 introduce a virtual imaplib2
The virtual imaplib2 first try to import imaplib2 when provided by the system.
If not provided or if the version is not supported, fallback on the bundled
imaplib2 version.

Distribution maintainers can now easily remove the bundled imaplib2 version if
they want to get it packaged outside of offlineimap.

We still want to provide imaplib2 by default because:
- this library is neither in Python core nor packaged by a lot of distributions;
- users expect to be able to run offlineimap by just downloading the tarball or
  after a git clone.

In order to avoid unexpected (too old) versions of imaplib2, we restrict the
supported versions of this librabry.

23f96ba880 Encode utf-8 argument for md5 function
Python3 accepts binary input for md5 function.

This patch is known to break setups using folder names not strictly conforming
the IMAP UTF-7 encoding. We always made it clear that such setup is unsupported
and might be broken at some point in time. See documentation about
'decodefoldernames' in the provided configuration file. This is why this patch
is considered introducing no regression for this use case.

Patches to support both Python 3 and Python 2 by re-encoding the MD5 in the
filenames are welcome. This likely requires a new CLI option to allow
backporting the feature for users downgrading or changing of Python environment.
