0dc8b5811c Store min and max ioclass size as percentage val 
Min and max values, keept as an explicit number of cachelines, are tightly
coupled with particular cache. This might lead to errors and mismatches after
reattaching cache of different size.

To prevent those errors, min and max should be calculated dynamically.

d9c987e068 Flush metadata after changing status of each sector 
In case of cleaning metadata used to be flushed only when status of whole cache
line changed to clean.

This patch ensures that metadata flush is triggered after changin status of each
single sector is cache line.

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.
