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.
