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.

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.

Easy fix for CORE-2591: High mutex wait ratio and degraded performance after some time of performing normally.

Let's field tests to show us whether we would need a more complex solution in order to utilize the shared memory better.
Also, changed the allocation granularity from 4 to 8 bytes, as our most common locks are equal or longer than 8 bytes now.
