72e079a880 lib/nvme: implement external IO processing 
This patch allows to send IO requests from external module to the nvme
device.

External module should call nvme_io_msg_ctrlr_start() to start IO message
producer on the controller and enable sending messages.

nvme_io_msg_send() is used to send IO to NVMe driver thread context,
where passed function will be called. Allowing the external module to
issue IO as needed.

NVMe driver users should poll spdk_nvme_io_msg_process() to move forward,
sending IO from external module and process their completions.
