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.

The 0th generator becomes unnamed. Only internal requests can access it (zero length names are not allowed from outside). RDB$GENERATORS is no longer a reserved name.System generators cannot be changed by user requests, but can be queried with gen_id(g, 0) if the permissions (ACL) allow that. We don't track dependencies on sys generators, it's not necessary.
