Refactored database-level info to be retrieved directly into the MON$
...
snapshot, without intermediate storage in shmem. This should also fix
CORE-5179 (Database-level statistics (MON$STAT_GROUP = 0) may contain
multiple rows under concurrent load).

This should fix the races while accessing the relation statistics inside dbb_stats. Reads/writes/fetches/marks are incremented (CCH) and read (INF) unprotected, as it's crash safe and read skews are acceptable. Other counters (both global and relation wise) are protected with a mutex. They're incremented on demand based on the attachment counters (via diffs). While being there, cleaned up the currently unused performance counters.

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.

Refactored database monitoring, made its handling attachment bound. This should make deadlocks impossible, as well as avoid blocking worker connections while the monitoring request is processed.

Work in progress (committed due to SF upgrade). Checked only on SS.

1. Frontported fix for CORE-3935 and CORE-3993.
2. Added debugging support for mutexes and rwlocks in Vulcan style.
Unfortunately after last 'svn up' build asserts in JrdStatement:71.

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.

Also some cleanups, the most important are:
- meaningful ctor on Jrd::Lock, helping to avoid code dup
- avoid unneeded h-file dependencies, making boot build engine dependent
