This change puts the DTLS handshake as payload of STUN packets with a custom STUN attribute (registered with the IANA) and starts the DTLS handshake before the ICE transport becomes writable. Effectively, STUN acts as a transport layer for DTLS during the handshake phase.
This will theoretically reduce the call setup time by one RTT for aggressive nomination or two RTTs for regular nomination.
The latest DTLS packet (flight) is cached and sent on every STUN request or response. DTLS packets are extracted from every authenticated STUN request or response and handled to the DTLS layer for processing.
The caching also increases the resilience to packet loss as STUN pacing is more aggressive (every 20ms) than the exponential backoff used by DTLS which should reduce call setup time in lossy networks.
If the other side of the connection does not support this feature the fallback to normal DTLS happens as soon as the ICE transport becomes writable. This also handles edge-cases like fragmentation of the DTLS handshake.
The feature is only supported when ECDSA certificates are used since RSA certificates are too large to transport as STUN attributes. The observed attributes for the server and client flights with the certificates were around 600 to 650 bytes. This may be further reduced by using raw public keys defined in RFC 7250.
This feature is disabled by default and guarded by the field trial
WebRTC-IceHandshakeDtls
and requires experimentation and standardization before roll-out in the browser.

- Make port_allocator depend only on port
- Move some constants from port.h into p2p_constants

RegisterReceivedPacketCallback is used instead of
sigslot::SignalReadPacket. The callback use a new data class ReceivedPacket that combine meta
data and packet payload from a received packet.
This is the first step in an attempt to cleanup the data types used in
the packet receive pipeline.
Eventually, the ReceivedPacket class can contain more meta data such as
ECN information.

This patch is a follow up to https://webrtc-review.googlesource.com/c/src/+/260943
which made it possible to destroy a Port before a Connection (on that
port).
This patch "reverses" this, by adding RTC_DHECK, and fixes the Port
destructor to release the Connections before invalidating the WeakPtr<>.
Currently there are no known occurrences where a Connection is destroyed after it's Port is. But prior to the change in Port destructor, a bunch unit tests failed on the newly added DCHECKs.
In addition:
a) modify StunReqquestManager to remove entry from hash before calling callback. This makes it possible for callback to modify (clear) hash.
b) clear pending requests when disconnecting from port, "should not be needed", depends on a)
c) add a getter for pending_delete()

As documented in webrtc:11908 this cleanup is fairly invasive and
when a part of a frequently executed code path, can be quite costly
in terms of performance overhead. This is currently the case with
synchronous calls between threads (Thread) as well with our proxy
api classes.
With this CL, all code in WebRTC should now either be using MessageHandlerAutoCleanup
or calling MessageHandler(false) explicitly.
Next steps will be to update external code to either depend on the
AutoCleanup variant, or call MessageHandler(false).
Changing the proxy classes to use TaskQueue set of concepts instead of
MessageHandler. This avoids the perf overhead related to the cleanup
above as well as incompatibility with the thread policy checks in
Thread that some current external users of the proxies would otherwise
run into (if we were to use Thread::Send() for synchronous call).
Following this we'll move the cleanup step into the AutoCleanup class
and an RTC_DCHECK that all calls to the MessageHandler are setting
the flag to false, before eventually removing the flag and make
MessageHandler pure virtual.

We now have two downstream users of stun.h, so it appears to be
generally usable. I put this in a new dir networking/, but I'm open to
suggestions here (maybe some things in api/ should move in there).
I checked what our downstream users are actually using, and it's
cricket::ComputeStunCredentialHash
cricket::<constants>
cricket::TurnMessage
cricket::GetStunErrorResponseType
cricket::StunAttribute::CreateAddress
cricket::StunErrorCodeAttribute
cricket::StunByteStringAttribute
StunAttribute::CreateUnknownAttributes
cricket::TurnErrorType
cricket::StunMessage
I reckoned that was pretty much everything in stun.h, so I didn't
bother splitting it up. They don't use every function and constant
in there, but all _types_ of functions and constants, so for the
sake of coherence I don't think it makes sense to split it.
There's some old stuff in there like GTURN which could arguably
be split out, but it should likely go away soon anyway, so I don't
think it's worth the effort.
Steps:
1) land this
2) update downstream to point to the new header and target
3) remove p2p/base:stun_types.
