Bug 933093 - Part 1: Add 'sendFile' interface to MozNFCPeer. r=khuey, sr=smaug
Bug 933093 - Part 2: Add 'sendFile' implementation to Chrome process. r=yoshi

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.
Bug 933093 - Part 3: Add system message 'nfc-manager-send-file'. r=fabrice

This message is notified to system-process to initiate Bluetooth's send file operation.
