Two new calls are added to NrIceCtx.
1) A static call to allow StunAddrsRequestParent to get stun addrs from the main
process.
2) A call to allow StunAddrsRequestChild to pass the new stun addrs back to
PeerConnectionMedia on the content process.
PeerConnectionMedia, when running in e10s mode, sets up the StunAddrsRequestChild
and makes the async request to get the stun addrs. When they are returned, it
sets the stun addrs in NrIceCtx avoid the network calls that would otherwise
cause a further restricted sandbox to fail.

PStunAddrsRequest.ipdl defines the new IPC protocol to get stun
addrs on the main process.
StunAddrsRequestChild requests the stun addrs from the parent.
StunAddrsRequestParent uses a static method on NrIceCtx to get the
stun addrs from the STS thead and sends the addrs back to the
child process.
NrIceStunAddr (nricestunaddr.{cpp|h}) wraps nr_local_addr and makes
it easier to serialize/deserialize over IPC.
NrIceStunAddrMessageUtils follows the pattern used by other Necko
IPC classes to define top-level serialization/deserialization
calls used by the IPC framework.
Modifications under netwerk/ipc are to connect the new IPC
protocol to get stun addrs to PNecko since it is a network
related IPC protocol.
