[v3,0/4] bidirect guest channel

  From: Marcin Hajkowski <marcinx.hajkowski@intel.com>

Extend guest channel API to allow bidirectional
communication. Modify power manager host and guest
side to communicate in both directions.

v3:
* fix global_fds[lcore_id] comparison to invalid value
* check 0 to verify if read function actually read some data
* define _NACK cmd instead of _NAK
* simplify rte_power_guest_channel_receive_msg func logic

v2:
* send ack only if power operation return positive value
* log diffent error for unexpected incoming command and
  error during ack/nak cmd sending


Marcin Hajkowski (4):
  power: fix invalid socket indicator value
  power: extend guest channel api for reading
  power: process incoming confirmation cmds
  power: send confirmation cmd to vm guest
