Zhi Huang 2dfc42d7b6 Prepare to make BaseChannel depend on RtpTransportInternal only.
Eventually we want BaseChannel to depend on the RtpTransportInternal
instead of DtlsTransportInternal and share RtpTransport when bundling.
This CL is the first step.

Add SetRtpTransport and Init_w(RtptransportInternal*) to BaseChannel.
These two methods would replace the existing SetTransports and Init_w
methods.

Add new CreateVoice/VideoChannel methods to the ChannelManager which
 take RtpTransportInternal instead of Dtls/PacketTransportInternal.

|cotnent_name| is removed from the SrtpTransport to simplify to code
since it is only used for debugging.

InitNetwork_n is removed from BaseChannel in CL as well.
