1. Cleanup - use Firebird::Semaphore instead of local events, removed code
...
related with local events from isc_sync.cpp.
2. Cleanup - removed unused parameter 'number of events' from ISC_event_wait()
and two unused parameters from ISC_event_init().
3. Added SYSV-semaphore based implementation of IPC to isc_sync.cpp.
This should fix CORE-2102: Firebird 2.5 does not build on MacOS (Darwin).
4. Fixed use of posic CS without (x)inetd (i.e. fb_inet_server -s).
5. Fixed (to be reviewed by Dmitry) recovery after some process death in lock manager.

1) Encapsulated the lock manager and integrated it into the engine.
...
2) Replaced "early" (before LM) checkouts with "late" (inside LM) ones.
3) Removed the mutex protection that's no longer necessary.
Note: the new LM contains some future code (currently commented out) which will be enabled and tested after the Alpha release.

Defer the process block cleanup till its death. This is dumber but more robust. It avoids races at LCK_fini() and fixes a rare deadlock there.

Major changes in the lock manager, targeted to allow mixed in-process/cross-process working modes. Namely, they are:
...
1) Separate process and owner blocks. Multiplex blocking signals via single blocking thread.
2) Enable direct in-process AST delivery.
3) Drop PREVENT_OWNER_STARVATION code as not compatible with the new LM structure.
4) Synchronize LM using its own mutex instead of SCH.
5) Implement wakeup'n'remap code for waiting owners.
6) Add more debugging points for memory remaps.
7) Cleanup and style.
Hopefully, this attempt is more POSIX-friendly than my previous one.

Fixed CORE-1671: atexit() calls in client libraries cause segfaults
...
and CORE-1079: Every attach of fbclient/fbembed library leaks 64KB of memory
To do it:
- created new template GlobalPtr, controlling access to destructors of global objects.
- applied it to global objects.
Also some related cleanup.
