Implement remote offerer support in js
Now you can check the "Remote offerer" checkbox in the JS example to force the peer to send the SDP offer. This involved implementing support for receiving the OFFER_REQUEST message in the C example.
As a side-effect of this, the C example will no longer send OFFER_REQUEST automatically when the --our-id option is passed. It will only do so when the --remote-offerer option is explicitly passed.
plus some misc fixes.
