e06832426d cleaner: Retrieve core object properly 
Cleaner doesn't set core object in req as it works in domain of cache
lines, which may belong to various cores. It this case should retrieve
core object not from the req, but from the map instead.

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.

be3b402162 Synchronization of collision table 
Adding synchronization around metadata collision segment pages.
This part of metadata is modified when cacheline is mapped/unmapped
and when dirty status changes.

Synchronization on page level is required on top of cacheline
and hash bucket locks to assure metadata flush always reads
consistent state when copying entire collision table memory
page.

82e8c55f4a Write-only cache mode

operations do not promote data to cache. Reads are mostly serviced
by the core device, only dirty sectors are fetched from the cache.
