/**
 * Creates and manages WebRTC connection requests
 *
 * For whitelisted peers, it'll always listen for 'offer' messages and answer to try to establish
 * the RTC channel. If a new one comes while the previous is waiting, it'll teardown the previous
 * request and answer the new.
 * For Raiden channel partners (on startup/channelOpen), targets, initiators and also upon new
 * messageSend.requests, it's checked if the peer is online, and in parallel with any callee
 * handling, a call is initiated, times out after a few seconds and is retried a few times (to be
 * retried again in any of the above events). The winner channel of the callee/caller race is used.
