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.

This did not work and is not usefull since the purge() method was introduced in
1410a391bc. Actually, the purge() does what deletemessagelist() was supposed to
achieve.

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
when no more thread need it.

I don't think the phrase "Free speech owns to anyone of us" is
grammatically correct, and I honestly don't know what the author
really meant, what does "owns" mean in this context? It could be that:
- You should own up to what you've said
- That we all "own" the right to free speech
I think the latter is probably more likely, in any case, submit a pull
request for this so this can be clarified.
