Alexey Rybalchenko 7fda980710 Update FairMQStateMachine & introduce FairMQChannels
Organize sockets as a map of vectors of FairMQChannels.

Update FairMQStateMachine by removing SETTINGINPUT, SETTINGOUTPUT,
BIND and CONNECT states and by adding INITIALIZING_TASK, RESETTING_TASK
and RESETTING_DEVICE states. Run states functions in their own thread.
