A couple of ODS changes :
...
- abandon page checksums and use page number for validation
- PIP have now pip_used field to track number of allocated pages
- two more flag bits per data page is now reserved on pointer page. One is for the swept flag and second is still not used but makes calculations easy
- misc changes
Don't forget to rebuild your DBs !

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.

Promote thread_data* as function argument. Only exception where both tdbb and dbb were left together as arguments is nbak.cpp's call to CCH_rollover_to_shadow to avoid any side effect in the changed code, but anyway, that function calls SDW_rollover_to_shadow that takes the dbb from the tdbb and not explicitly.
