The chrome process is the arbitrator / mediator between the content process that issued the nfc 'sendFile' operation and the system-process (content) that is responsible for performing handover to an alternate carrier(AC).
The chrome process notifies the system process through a 'nfc-manager-send-file' system-message to initiate the handover process.
The system-process subsequently handovers the data to alternate carrier's (AC's : BT / WiFi) 'sendFile' interface.
Add two new P2P IPC messages 'CheckP2PRegistration' and 'NotifyUserAcceptedP2P'
to establish User Communication on P2P UI from content process to chrome process. These IPC messages are needed to support basic PeerToPeer use cases.
