Refactored NBackup subsystem.
...
1) Fixed CORE-1696 - "Deadlock in LM by using nbackup utility" with priority rating of lock requesting for LCK_backup_database and LCK_bdb.
2) A lot of stability fixes were made.
3) The key thing is using new GlobalRWLock for removing LCK_set_owner_handle function and speed up performance.
4) The code is still ready for using both in shared cache architecture and in claster architecture.

This change affects GenericMap only, as it's used globally in a few places and we have a proven crash there.
I have a more complete solution (total cleanup of default accessors from BePlusTree and SparseBitmap) in my local tree (thanks to Dmitry Kovalenko), but it's incomplete (requires more changes inside the engine) and IMHO risky (~20 core modules are affected), so I'd like to defer finalization of this cleanup till v3.0.
All objects of these types seem being protected by dbb_sync, so they shouldn't cause us any problems currently.
