6ac3195823 Keep stop pipeline in struct cache. 
To eliminate possibility of allocation error in cache stop, pipeline is
allocated on attach.

Due this change, the only possible non-zero status of  ocf_mngt_cache_stop() is
just a warning and cache is always stopped after executing it.

13cf871a13 Per-execution-context freelists 
Global free cacheline list is divided into a set of freelists, one
per execution context. When attempting to map addres to cache, first
the freelist for current execution context is considered (fast path).
If current execution context freelist is empty (fast path failure),
mapping function attempts to get freelist from other execution context
list (slow path).

The purpose of this change is improve concurrency in freelist access.
It is part of fine granularity metadata lock implementation.

917cbd859a Add promotion policy API and use it in I/O path

eliminating one-hit wonders being added to cache and polluting it.

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.
