d88a4ac57a Do not allow top volume I/O on management queue 
Core volume I/O must not be queued on management queue - this would
break I/O accounting code, resulting in use-after-free type of errors
after cache detach, core remove etc.

from the user down to bottom volume open callback. volume_params

c5df82f2cb Make management API asynchronous 
NOTE: This patch only changes API that pretends to be asynchronous.
Most of management operations are still performed synchronously.
The real asynchronism will be introduced in the next patches.

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.
