db06783d56 Fix cache stats updating. 
When single request to cache was issued, stats updating function was called with
0 bytes as value to update. In case of many request issued to cache, stats were
updated only in case of error.

1525e85805 Add global random seed config 
This is needed to make fuzzy tests work with xdist as each
xdist gateway expects to receive the same set of parameter
values, which for random generators may be achieved only by
providing globally shared seed.

09b68297b2 Revert "Optimize cacheline locking in ocf_engine_prepare_clines" 
This change introduced a race condition. In some code paths after
cacheline trylock failed, hash bucket lock needed bo be upgraded
in order to obtain asynchronous lock. During hash bucket lock
upgrade, hash read locks were released followed by obtaining
hash write locks. After read locks were released, concurrent
thread could obtain hash bucket locks and modify cacheline
state. The thread upgrading hash bucket lock would need to
repeat traversation in order to safely continue.

This reverts commit 30f22d4f47.

8426d662cb Changed err handling to BUG_ON in case of refcnt_int fail durign cache init. 
Since we do not expect that incrementing cache's reference counter
during cache init will fail at any condition it is can be changed
to an assert instead of error handling.
