46d2457deb Fixed invalid filtering of SCTP datachannel packets on high ports.
Packets on source ports 32768-49151 got identified as RTP packets by
"IsRtpPacket" and were ignored by the SCTP transport.

This CL changes this to check the packet flags for "PF_SRTP_BYPASS".

8d517c4170 Rewrite of sigslot that avoids vtables.
This reduces binary size considerably and solves some other problems.

Also rewrote using variadic templates.

f534659ee6 Adding ability for BaseChannel to use PacketTransportInterface.
... As opposed to DtlsTransportInternal.

The code is suboptimal right now, storing two pointers to the different
interfaces. This will all be cleaned up when we have an "RtpTransport"
abstraction that BaseChannel can use.

This CL also cleans up the "fake transport" classes a bit, and gives
them their own header files.

b2cdd93fd6 Remove the dependency of TransportChannel and TransportChannelImpl.
DtlsTransportChannelWrapper is renamed to be DtlsTransport which inherits from
DtlsTransportInternal. There will be no concept of "channel" in p2p level.
Both P2PTransportChannel and DtlsTransport don't depend on TransportChannel
and TransportChannelImpl any more and they are removed in this CL.

6ce9259cb0 Revert of make the DtlsTransportWrapper inherit form DtlsTransportInternal (patchset #11 id:320001 of https://codereview.webrtc.org/2606123002/ )
Reason for revert:
Failed the memory check.
May need to fix the memory leak.

953c2cea5e Reland of: Separating SCTP code from BaseChannel/MediaChannel.
The BaseChannel code is geared around RTP; the presence of media engines,
send and receive streams, SRTP, SDP directional attribute negotiation, etc.
It doesn't make sense to use it for SCTP as well. This separation should make
future work both on BaseChannel and the SCTP code paths easier.

SctpDataEngine now becomes SctpTransport, and is used by WebRtcSession
directly. cricket::DataChannel is also renamed, to RtpDataChannel, so it
doesn't get confused with webrtc::DataChannel any more.

Beyond just moving code around, some consequences of this CL:
- We'll now stop using the worker thread for SCTP. Packets will be
  processed right on the network thread instead.
- The SDP directional attribute is ignored, as it's supposed to be.

c0dad89bed Revert of Separating SCTP code from BaseChannel/MediaChannel. (patchset #14 id:240001 of https://codereview.webrtc.org/2564333002/ )
Reason for revert:
Hitting DCHECK in chromium's WebrtcTransportTest.TerminateDataChannel and WebrtcTransportTest.DataStreamLate. Will investigate and reland.
