1) Slightly refactored recheduling and checkout logic.
...
2) Re-enabled checkouts in PIO routines, this resolves CORE-4179. Windows build may be broken, please validate.
3) Implemented faster reaction on asynchronous cancellation/shutdown requests.
4) Avoided locking dbb_sync in AST. This change also solves races during massive attachment shutdown.

Improvement CORE-4935 : Increase performance of backout of dead record version (or undo of just created primary record version) when backversions chain is too long

Improvement CORE-4936 : Reduce internal contention in background garbage collector
Other small improvements:
- garbage collector\sweep now skip record header if transaction is below OIT - it allows to reduce number of page fetches
- missed points to gather RECORD_FRAGMENT_READS and RECORD_BACKVERSION_READS statistics

2) Protected against an undo record being used in VIO modify/erase/writelock routines.

5) Reduced the in-memory size of the undo log.
6) Slightly better alternative to the legacy NULL reporting for outer joins.
7) Minor fixes and adjustments in BufferedStream.
