228c5fc891 Get rid of req->io_if 
Remove one callback indirection level. I/O never changes it's direction
so there is no point in storing both read and write callbacks for each
request.

07d1079baa Add LOOKUP_REMAPPED status to allow iterative cacheline lock 
Allowing request cacheline lock to be called on partially
locked request. This is going to be usefull for upcomming
eviction improvements, where request will first have evicted
(LOOKUP_REMAPPED) cachelines assigned to it in a locked state,
followed by standard request cacheline lock call in order to
lock previously inserted (LOOKUP_HIT) or mapped from freelist
(LOOKUP_INSERTED) cachelines.

82e8c55f4a Write-only cache mode 
Write-only cache mode is similar to writeback, however read
operations do not promote data to cache. Reads are mostly serviced
by the core device, only dirty sectors are fetched from the cache.
