Bug 1345511 - pt 2 - add IPC mechanism for getting stun addrs on main process. r=bwc 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. MozReview-Commit-ID: GyEapBe5krl
