91e0345b78 Implement asynchronous attach, load, detach and stop 
NOTE: This is still not the real asynchronism. Metadata interfaces
are still not fully asynchronous.

e53944d472 Dynamic I/O queue management 
- Queue allocation is now separated from starting cache.
- Queue can be created and destroyed in runtime.
- All queue ops accept queue handle instead of queue id.
- Cache stores queues as list instead of array.

5c81824a8d Added mechanism for preventing dirty requests. 
Instead of switching write policy to pass-through, barrier is rised
by incrementing counter in ocf_cache_t structure.
