2abccadb9e New error code for invaild loaded cache name. 
When loading cache metadata, it should be started with exactly the same name as
it was running previously. Otherwise load should fail and return newly added
error code.

42d6dbbf11 Remove low-level stats getters from public API. 
Since stats builder is implemented for retrieving cache, core and ioclass stats,
adapters should use it instead.

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.

Nop cleaning policy now returns new 'OCF_CLEANER_DISABLE' macro which indicates
that cleaing shouldn't be performed. To enable it back, ocf_kick_cleaner()
should be called.
