Include platform definitions file common.h in firebird.h. Use OS-specific ThreadId instead artificial FB_THREAD_ID, avoiding unneeded casts in the code. This should fix BSD and MAC ports.

Allowed multiple waiting requests per owner. This resolves various crashes and asserts in the SharedDatabase + SharedCache mode. Page-level deadlocks are still expected, the cache manager needs fixing.

Also, made the lock table synchronization a bit stricter. Some refactoring and cleanup was performed as well.

1. Cleaned up most of SUPERSERVER usage.
...
SUPERSERVER has 4 different meanings in our code:
- this is milticlient server (replaced with Config::getMultiClientServer())
- use shared data cache (replaced with Config::getSharedCache())
- use shared metadata cache (replaced with macro SHARED_METADATA_CACHE)
- database are NOT shared between processes (replaced with getSharedDatabase())
2. Use fb_smp_server as both superclassic and classic binary on posix
(xinetd autodecection is done).
3. Small posix build cleanup.

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.

2) Replaced "early" (before LM) checkouts with "late" (inside LM) ones.

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.
