Front ported:
...
1. Improvement CORE-4431 : Reduce contention for allocation table lock while database is in stalled physical backup state
2. Improvement CORE-4432 : Let attachments to not block others when allocation table is read first time
3. On Windows, file can not be deleted while system writes cached data into it, even if file is not open by anyone.
Therefore flush delta file implicitly before closing it.

Attachments marked as shutdown may still be running (before they reach the rescheduling point), so they should not be accounted as already gone. This should also fix CORE-4236: Database shutdown is reported as successfully completed before all active connections are in fact interrupted.

Unconditionally flush the page cache to disk if FLUSH_ALL / FLUSH_FINI modes are used and FW=OFF. This puts a little bit more consistency and favors explicit flushes over implicit ones (e.g. when database is detached and its file is closed).

Modified IStatement interface in our API:
...
1. Never allocate empty statement - always use att->prepare() to create statement interface
2. Separated IStatement into 2 parts - statement itself and resultset.
3. Added stmt->openCursor() (and att->openCursor() for unprepared statements) to create IResultSet.
4. Always use IMessageMetadata (former IParametersMetadata) to pass message fromat info from client,
therefore avoiding need in BLR generation in client applications.
