0703856b53 Add SafeClamp(), which accepts args of different types
Specifically, just like SafeMin() and SafeMax() it handles all
combinations of integer and all
combinations of floating-point arguments by picking a
result type that is guaranteed to be able to hold the result.

This CL also replaces a bunch of std::min + std:max call pairs with
calls to SafeClamp()---the ones that could easily be found by grep
because "min" and "max" were on the same line. :-)

Connection::nominated() is updated to mean
(remote_nomination_ || acked_nomination_), which means both a
controlling and controlled agent can be said to be "nominated".
Previously this was (remote_nomination_ > 0) which only applies to the
controlling agent.

PortTest.TestNomination added to test nomination values and nomination
stat.

This value is surfaced through cricket::ConnectionInfo::nominated.
RTCStatsCollector uses this value in its collection of
RTCIceCandidatePairStats.

RTCStatsCollectorTest.CollectRTCIceCandidatePairStats updated to test
that ConnectionInfo::nominated is surfaced using mocks.
rtcstats_integrationtest.cc updated to expect nomination set without
using mocks.

d030912de4 Pick the DTLS handshake timeout based on the ICE RTT estimate
This CL replaces the previously-hardcoded DTLS timeout value of 50 ms with one that is picked dynamically as 2x ICE RTT (clamped between 50 and 3000 ms to keep it reasonable).

No tests yet - I'm working on these, but sending out this CL early to get feedback. I've tested it manually and on slow networks it results in successful DTLS setup in a single attempt - instead of clogging up the slow link with multiple retransmissions as done previosly.

5107246d4b Allow applications to limit the ICE check rate through RTCConfiguration
If an application sets a non-null value in RTCConfiguration.iceCheckMinInterval, we do not sent STUN pings more often than that. This is useful for bandwidth constrained scenarios.

This CL also increases the maximum STUN ping timeout to 60 seconds up from its previous value of 5 (which meant that a ping response received 5 seconds later would not be counted), and allows the RTT estimate to go up to 60 seconds from its previous limit of 3. RTTs above 3 seconds are possible on mobile links. (webrtc:7109)

This CL was originally written by pthatcher@, I am just submitting it after a minor cleanup.

ede5da4960 Replace ASSERT by RTC_DCHECK in all non-test code.
Bulk of the changes were produced using

  git grep -l ' ASSERT(' | grep -v test | grep -v 'common\.h' |\
    xargs -n1 sed -i 's/ ASSERT(/ RTC_DCHECK(/'

followed by additional includes of base/checks.h in affected files,
and git cl format.

Also had to do some tweaks to #if !defined(NDEBUG) logic in the
taskrunner code (webrtc/base/task.cc, webrtc/base/taskparent.cc,
webrtc/base/taskparent.h, webrtc/base/taskrunner.cc), replaced to
consistently use RTC_DCHECK_IS_ON, and some of the checks needed
additional #if protection.

Test code was excluded, because it should probably use RTC_CHECK
rather than RTC_DCHECK.

State and priority added to ConnectionInfo. The Connection::State enum
is replaced by IceCandidatePairState enum class.

At P2PTransportChannel::GetStats, Connection::stats is called, producing
ConnectionInfo for the connection that is then filled in with additional
values from the Connection. This is refactored so that all values are
set by Connection::stats.

RTCStatsCollector is updated to surface the ConnectionInfo stats.

62351c9923 Fixing problems with ICE candidate pair prioritization.
The main issue was that upon receiving a binding response with a srflx
mapped address attribute, the local candidate was not updated from local
to srflx. This means the two ICE agents view the same pair differently;
one sees it as "X<->srflx" while the other sees it as "local<->X". This
causes sub-optimal prioritization and could result in the wrong pair
being selected if using aggressive nomination.

The other issue was that TCP prflx candidates were not differentiated from
UDP prflx candidates. This lead to TCP prflx candidates prioritized above TCP
host candidates.

After fixing these issues, I was able to re-enable many disabled tests, as well
as restore the check for the candidate types of the controlled agent.

Add an ICE nomination attribute. If a connection switched on the controlling side, increase the nomination value set in the attribute.
The controlled side will also be ready for re-nomination option; it will switch if a nomination comes with a higher nomination value even though it may be at a lower priority.
Plus, don't nominate or re-nominate if the nomination value at the current connection has been acknowledged.

If a port is not used by any channel and if it has no connection for 30
seconds, it will be removed.
Note, as long as a port is used by a transport channel, it will be kept
even if it does not have any connection. This will be beneficial to
continual gathering because new connections can be created in the future
when network changes.

If all connections on a port is destroyed, it will schedule an event
to check if it is dead after a timeout. Previously if a new connection
is created but destroyed before the event is fired, it will destroy the
port. With this change, we will not destoy it until it times out again
after the last created connection is destroyed.

b825aee04a Start ICE connectivity checks as soon as the first pair is pingable.
Previously, we were starting a periodic timer when the local
description was set. The first connection may be created at any
time after this happens, so after creating the first connection, we
need to wait until that timer next fires before sending a ping.

Now we just start that timer (and send the first ping) immediately
after the first connection becomes pingable.

This CL also removes the "Connect" method. The only vestigal
effect of this method was to start the periodic timer, which is
now not needed since it happens automatically.

3159ffae6b Revert of Do not delete a connection in the turn port with permission error or refresh error. (patchset #6 id:260001 of https://codereview.webrtc.org/2068263003/ )
Reason for revert:
It broke webrtc builds.

Original issue's description:
> Do not delete a connection in the turn port with permission error,  refresh error, or binding error.
>
> Even if those error happened, the connection may still be able to receive packets for a while.
> If we delete the connections, all packets arriving will be dropped.

f7c15a9159 Set the generation on peer reflexive candidates when created.
If an actual peer reflexive candidate was created (and not one that
would just be replaced by a different candidate later), we weren't
setting the generation value. This means that new-generation prflx
candidate pairs weren't being prioritized above the cross-generation
pairs, or above relay<->relay pairs.

435264a183 Increase the stun ping interval.
Writable connections are pinged at a slower rate.
The function IsPingable will filter out the writable connections.
The interval for slower ping rate by default is WRITABLE_CONNECTION_PING_INTERVAL(2500ms) and can be set with the configuration.

5d97a9a05b Adding more detail to MessageQueue::Dispatch logging.
Every message will now be traced with the location from which it was
posted, including function name, file and line number.

This CL also writes a normal LOG message when the dispatch took more
than a certain amount of time (currently 50ms).

This logging should help us identify messages that are taking
longer than expected to be dispatched.

18f9da0286 Fix a memory issue when calling LOG_J in port.cc
The connection delete  message may be processed when a port is being deleted.
Calling LOG_J here needs to access the port object that may have been partially released.
This fixes the memcheck bot failure.

36f50e8e4e Create a new connection if a candidate reuses an address
If the remote side sends a candidate with the same address and port with an existing candidate,
but with a new ufrag and pwd, the local client will create a new connection from it
and destroy the old connection with the same remote address.

the transportcontroller is not notified.

417eebe5dd Fixing the behavior of the candidate filter with pooled candidates.
According to JSEP, the candidate filter does not affect pooled
candidates because they can be filtered once they're ready to be
surfaced to the application.

So, pooled port allocator sessions will use a filter of CF_ALL, with a
new filter applied when the session is taken by a P2PTransportChannel.

When the filter is applied:
* Some candidates may no longer be returned by ReadyCandidates()
* Some candidates may no longer have a "related address" (for privacy)
* Some ports may no longer be returned by ReadyPorts()

To simplify this, the candidate filtering logic is now moved up from
the Ports to the BasicPortAllocator, with some helper methods to perform
the filtering and stripping out of data.

351d77b702 Update the type and cost of existing networks
if the network monitor detects it after the native code does.

Also set the network cost for ethernet, wifi, unknown, cellular network type to be 0, 10, 50, 900,
so that unknown networks will have lower precedence than known networks with low cost (like Wifi) but  higher precedence than known networks with high cost.

And third, infer network type based on limited name matching in Android if there is no network monitor or network monitor did not find the type.

a1c303535f Relanding: Implement RTCConfiguration.iceCandidatePoolSize.
Depends on this CL in order to work in Chromium:
https://codereview.chromium.org/1976673002/

It works by creating pooled PortAllocatorSessions which can be picked up
by a P2PTransportChannel when needed (after a local description is set).

This can optimize candidate gathering time when there is some time between
creating a PeerConnection and setting a local description.
