10c3c3de36 Renaming hash bucket locking functions
1. new abbreviated previx: ocf_hb (HB stands for hash bucket)
2. clear distinction between functions requiring caller to
   hold metadata shared global lock ("naked") vs the ones
   which acquire global lock on its own ("prot" for protected)
3. clear distinction between hash bucket locking functions
   accepting hash bucket id ("id"), core line and lba ("cline")
   and entire request ("req").

Resulting naming scheme:
ocf_hb_(id/cline/req)_(prot/naked)_(lock/unlock/trylock)_(rd/wr)

5538a5a95d Only request evict size equal to request unmapped count
Removing the logic for oportunistic partition overflow
reduction by evicting more cachelines than actually
required by the request being serviced.

3a7b55c4c2 Don't evict on hit
If request is hit, simply try to acquire cachelines instead of verifying
whether target partition's size is not exceeded.

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.
