Avoid a sweep pass for temporary tables, as the sweeper always sees those tables as empty, but even setting them up as empty has a non-zero cost.

Additional patch for improvement CORE-3362 : Cursors should ignore changes made by the same statement.
...
- SubQueryNode (sub-select's) and RseBoolNode (exists(), in\any\all) now knows if it is a part of some outer select (ForNode) or it is a standalone statement.
- VIO\get_undo_data was reworked to better fit undo-log implementation, corresponding changes in VIO_chase_record_version also done
- AV in VIO\get_undo_data was fixed

1) Removed the no longer actual "parent lock" concept from both the lock and event managers.
...
2) Reworked the lock manager synchronization: added the RAII mutex holders and avoided dirty reads for the shared memory.
3) Encapsulated lck_length into the Lock class + small related refactoring.
4) Front ported recent fixes from the v2.x branches.
5) Misc cleanup.

- Got rid of the fixed array that kept the stream count in the first element and 255 streams after it.
...
- Changed streams from UCHAR to ULONG as Dmitry wanted
- Got rid of some redundant flags to indicate BLR level
- Misc changes (for example, converted to test for DBB_read_only in Database to a function)
- BLR v6 is left commented (waiting for a better solution to appear, if any exists)
- This change is not going to raise the engine limits until a solution is found to express more than 255 streams in BLR.

Refactoring of runtime statistics and related classes:

- moved relation's counters into RuntimeStatistics.h

- removed dependency of RuntimeStatistics.h from ntrace.h

2) Opened the gates to implement the standard USAGE privilege (CORE-2884). SQL support and validation logic are still to be developed.
3) Added the grant option to the owner permissions for packages, procedures and functions.

Reworked the garbage collector thread:
...
- a single try-catch block looks better
- cross-helping between GC and CW/CR threads is agreed to be a bad idea
- replaced ATT_disable_gc_notify with a check inside notify_garbage_collector()
- made the logic more straightforward
Careful review would be appreciated.
