Reverted back to the single-pass algorithm used in v2.x. This should work around the issue with non-zero-timeout shutdown in SC.

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.

Use status interface instead plain status vector when working with exceptions.

Avoid use of circullar allocation for strings in status vector (except when unavoidable for ISC API backward compatibility).
Use TLS for circullar allocation buffer instead manually working with threads' list.

Added the initialization timestamp to shmem regions. Modified the lock print output to report this timestamp. This is useful to know as all the counters inside the lock table are incremental and a baseline is required to make any time-based estimations.

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.
