+++ This bug was initially created as a clone of Bug #28705 +++

I decided to split this out as a separate bug and give it its own branch, so I
can merge some of the other stuff from #28705. Below is the discussion that has
been had on the issue so far.

>> Maybe PleaseRestartICE() should have a matching property for recoverability?
> Haven't addressed this. Could this be done by exposing the CM's view of the
> state machine for the stream, or would you say that it is orthogonal? Also, you
> say that LocalCredentials is mostly useful for debugging. Could we just set it
> to "", "" but not clear LocalCandidates when we emit PleaseRestartIce?

<alsuren> ocrete: what do you think of
http://git.collabora.co.uk/?p=user/alsuren/telepathy-spec.git;a=shortlog;h=refs/heads/IceRestarts
?
<alsuren> ocrete: if LocalCredentials is looking too much like conflated design
then I'm happy to scrap that commit, and add a property tomorrow

<ocrete> why do we clear the local cands on a ice restart ?
<ocrete> don'T have to do that
<ocrete> they shouldnt change
<alsuren> ocrete: if we are a gateway then the controlling endpoint might have
changed?
<alsuren> though other things probably break in that use case
<alsuren> mostly just me getting confused with RemoteCandidates
<ocrete> hmm maybe
