4be5fc6d37 Quick improvements to RepGraph actor prioritization: 
-Always prioritize connections' ViewTargets and OwningActors, since they're usually the most important and could get starved out by other actors.
-Increase the default MaxDistanceScaling from 30m to 600m, since 30m didn't have much effect.

  MAJOR FEATURES & CHANGES
============================

Change 3809757 by Jon.Nabozny

	Fixup BuildPhysx to only set up HTML5 when needed.

Change 3812325 by Jake.Leonard

	Fix keyed debug messages from getting scaled to 0 and thus not appearing at all. This appears to be a bug in main as well. Only -1 keyed messages (which are handled differently) will display anything at all as the scale application was removed.

	#Jira UE-53579

Change 3828032 by Jon.Nabozny

	Make sure the State is set before triggering delegates in FLwsWebSocket.

Change 3837391 by John.Barrett

	NetcodeUnitTest updates for better CIS/automation support.

Change 3837392 by John.Barrett

	Fixed performance issue with processing piped output for large numbers of unit tests, and fixed unit test windows overlapping - plus other bugfixes.

Change 3837397 by John.Barrett

	Moved a unit test to the 'Obsolete' folder.

Change 3837476 by John.Barrett

	Reduced unwanted OSS-null logspam.

Change 3844506 by Jake.Leonard

	Implementing missing steam leaderboard implementations. Also streamlines and fixes the friends leaderboard too.

	#Jira UE-53474,UE-53475,UE-53476

Change 3844803 by Jake.Leonard

	Fixing the Steam Leaderboard to allow for overwrite instead of increment.

	Please see Jira for recent comments

	#Jira UE-24791

Change 3844829 by Jake.Leonard

	Does the following:

	* Add message on the screen while the presence test is running to let users know that the test is still running.
	* Remove the FUniqueNetIDString dependencies in the test
	* Fix the Steam Rich Presence from having to do an unnecessary cast

	#Jira UE-53066,UE-54177

Change 3851997 by Jake.Leonard

	Remove one of the double steam p2p dump prints. Now the socket subsystem is the only one that prints, which will cover more cases anyways and limits the potential of duplicate prints.

	Also changes the dump interval to 10s from 3s.

	#Jira: UE-53763

Change 3882307 by John.Barrett

	Fixed packet flooding protection, and handling of packets with errors, so that they don't delay further packet processing.
	When there's an error receiving a packet, make sure the wrong/previous-packets address isn't used for logging.

Change 3882311 by John.Barrett

	Restricted socket recv code from CL 3026398/3209824 to TCP, as with UDP it prevented telling the difference between the socket having no data to receive, and receiving a 0-length UDP packet.

	This is important for protecting against DoS attacks.

Change 3894785 by Jake.Leonard

	Fix replays not ending properly when the user goes to end their PIE instance.

	#Jira UE-54488

Change 3902627 by Jake.Leonard

	Fix the demo time values being incorrect if our delta would push us to the end of the replay. Since we're done, we early out of the functions before we have a chance to update the DemoCurrentTime variable. This causes issues with UI elements as it looks like the replay is not over but it actually is.

	#Jira UE-54483

Change 3902632 by Jake.Leonard

	Fix voice issues on seamless travel for NullOSS

	#Jira UE-54899

Change 3904775 by Jake.Leonard

	Properly grab the correct world context (we were sometimes grabbing the editor instead, when we wanted the PIE world). These changes will allow us to reliably end the demos. Improves the fix in 3894785.

	#Jira UE-54488

Change 3968022 by Ryan.Gerleve

	PR #4538: Guarantee Return Value of 0 When GetPortNo() Fails (Contributed by XenonicDev)


Change 3994505 by Jake.Leonard

	Fix some shootergame minor bugs:

	1. If there's no map selector UI option, just search for all maps. This fixes the only seeing Sanctuary bug (first option in the maplist)
	2. Always make the server push gametype (which is just TeamDeathmatch by default)

	#Jira none

Change 3999511 by Jake.Leonard

	FArchive serializer for FUniqueNetIdSteam

	#Jira none

Change 4014550 by Jake.Leonard

	Fix Steam Dedicated Server from linking steamclient dlls, which should not be necessary.

	This fix introduces a new launch argument (-force_steamclient_link) that can be used to force the steamclient link anyways for licensees who might have required this under extreme circumstances.

	#Jira UE-55183

Change 4017165 by Jake.Leonard

	Modification of the leaderboard test interface to add more tests as well as arbitrary rank fetches.

	Command is "online test leaderboards [optional arbitrary user id for lookup]"

	#Jira UE-53533

Change 4017215 by Jake.Leonard

	Fix MULTIHOME returning the incorrect ip address on Linux and Android

	#Jira UE-57463

Change 4024116 by Ryan.Gerleve

	Fix for the transform of spawned rollback actors in replays now that gc is not guaranteed to happen between the destroy and respawn

	#jira none

	#AUTOMERGE using branch FNMain->DevNetworking of change#3876761 by Brian.Bekich on 2018/02/07 11:06:24.

Change 4024119 by Ryan.Gerleve

	Engine Changes Summary
	-------------------------------------------

	UNetConnection::>ActorChannels no longer public. This is to prevent code from adding/removing actor channels from underneath the ReplicationDriver.

	UActorChannel::Close() returns int64 for num bits written. int64 is used because that is what FBitWriter uses.

	UNetconnection::DestroyedStartupOrDormantActorGUIDs now private. Add/Remove/Reset methods are exposed. This is so RepDriver can intercept these calls (when present).

	Added USimulatedClientNetConnection. Use net.SimulateConnections command to add them.

	New UNetDriver::ForceNetUpdate function. Notifies replication driver that force net update was called.

	UNetDriver::DestroyedStartupOrDormantActors now wraps the FActorDestructionInfo in TUniquePtr. This is so pointers to destruct infos are stable within the map and rep driver can keep track of them in its own list.

	UNetDriver::GetFunctionRepLayout exposed as ENGINE_API for RepDriver use.

	UNetDriver::ProcessRemoteFunction changes a bit.
	-Forwards to RepDriver if present. The intention is to give RepDriver the chance to change routing logic and do its own traffic bookkeeping on the RPC.
	-A new function, ProcessRemoteFunctionForChannel exists for the meat of the RPC call which RepDriver probably doesn't want to change and is free to call.
	-Removed FRepLayout::SendPropertiesForRPC first UObject parameter because it was not used.

	New function UNetDriver::NotifyActorDormancyChange for when actor dormancy changes.

	New Functions UNetDriver::AddNetworkActor/RemoveNetworkActor. These forward to the rep driver if present.
	-Really want to get rid of public access to GetNetworkObjectList() outside of net code. Doesn't seem easy without breaking backcompat.

	New Function UNetDriver::NotifyActorTearOff for when tear off happens.
	-bTearOff is public though. RepGraph requires the explicit TearOff() call to notify the system about tear off actors. I'm not sure how to fix this with deprecation warnings. (Keep variable public but warn if accessed)

	New UNetDriver::RemoveClientConnection function should be the only place that removes ClientConnections. Forwards to RepDriver.
	-Again, would like to make ClientConnections private but it is used all over the place. (Thankfully only one place removes from it).

	New UNetDriver::NotifyActorFullyDormantForConnection. So RepGraph can intercept and do its book keeping.

	Made UNetDriver::IsLevelInitializedForActor public.

	Made UNetDriver::FlushActorDormancyInternal to hold common code that happens when Dormancy is flushed or changes.

	FNetworkObjectList::FindOrAdd has optional bool parameter for if actor info was actually added.

	UWorld has new delegates for when all starting actors are initialized and registered with networking.
	-TODO: NavSystem and AI system should make use of this. The currently has direct function calls into them.

	Moved checks for bPendingDormancy/Dormant into UActorChannel::StartBecomingDormant rather than at the callsite(s).

	Added GReplicationGatherPriortizeTimeSeconds, GServerReplicateActorTimeSeconds, GReplicateActorTimeSeconds, GNumReplicateActorCalls. These are for new Replication CSV stat group (disabled by default).

	FObjectReplicator::QueueRemoteFunctionBunch drops MustBeMappedGUIDs if it suppresses the RPC call. This fixes a bug that exists in both systems.

	UWorld::SpawnActor now adds network actor after PostSpawnInitialize rather than prior. This is so the initial location of the actor can be used.
	-Deferred actor spawning can still make this not the case, but without this change there is no chance of the actor location being correct.
	-In this case, I care about this for FN building actors who do not use deferred spawning.

	Added STAT_NetServerGatherPrioritizeRepActorsTime which is the total Server Rep Actor time minus the time spent in ReplicateActor.

	-Removed STAT_NumRelevantActors because it made no sense (set to whatever connection repped last).
	-STAT_NumReplicatedActors now sum of replicated actors on all connections for the frame.
	-STAT_NumReplicatedActorBytes now sum of replicated property bytes on all connections per frame. Does not track package map guid bytes.

	-FRepLayout BuildSharedSerializationForRPC/ClearSharedSerializationForRPC exposed as ENGINE_API for RepGraph to use.

	Non Networking Engine Changes:
	Added optional RenderColor parameter to K2_DrawBox.

	ULevel::HasVisibilityChangeRequestPending and ULevel::IsNetActor exposed as ENGINE_API so ReplicationGraph module can call it.

	Added AHUD::OnHUDPostRender callback for easier debug huds that don't revolve around players or debug actor targets.

Change 4024213 by Ryan.Gerleve

	UDemoNetDriver now properly associates actor channel close bunches with the actor's level. Fixes ensures & asserts that were occurring during replay playback due to trying to handle these channel closes while the level was streamed out.
	Moved the check for IsRecording in the ConditionallyCreatePacketManager functions to an if, since the check can now be triggered while the demo net driver is shutting down.

Change 4024217 by Ryan.Gerleve

	Fix for placed actors not respawning in some cases when scrubbing in a replay: don't add startup actors that are destroyed due to level streaming out to a replay checkpoint's destroyed actor list. Added some verbose (off by default) logging to help detect these cases.

Change 4024394 by Ryan.Gerleve

	Fix crash in rep graph when spatialization gets rebuilt while dormancy actors were in a particular state.

	Dormancy nodes still had delegates registered for their contained actors. Though they dumped the list of actors, they would still get notification when the actors' dormancy changed which would cause them to readd the actors some times. If these nodes overlapped between rebuilds, actors could get readded to the same node twice which ultimately leads to them not being fully removed when they do get destroyed, and garbage AActor* trying to replicate. Net.RepGraph.Verify can catch these problems.

	To fix, we are going to MarkPendingKill the GridCell nodes rather than keeping them around and just reseting their actor lists. They will get recreated as needed.

	They could have also manually unregistered each of their delegates but this is more complicated and probably performs worse overall (though spatial rebuild is rare/should never really happen in a  real game). Just marking the uobject pending kill will suppress the delegate callbacks to the nodes.

	More robust fix for rep graph having multiple channels for the same actor open simulataneously. Guarded behind CVar_RepGraph_FixDuplicateChannels.
	Add a replication driver hook for UActorChannel::CleanUp.
	Don't replicate actors or RPCs if the channel is closing.
	Don't clear the channel pointer on FConnectionReplicationActorInfo as soon as the channel closes, but wait until it's cleaned up to either clear the channel if the actor's dormant or remove the actor info from the map completely otherwise.
	Fixed missing include in ReplicationGraphDebugging.

Change 4024424 by Ryan.Gerleve

	Replication Graph. These are mostly for engine related purposes/cleanup.

	-Don't remove TornOff actors from rep graph when they are destroyed. They are removed when they are torn off already. Fixes benign log warnings.
	-When an actor causes spatialization rebuild, set the bias such that the actor is in the middle of new cell. This mitigates the issue where spatialization would be rebuilt every frame once an actor moves "away from the grid".
	-When rebuilding spatilization, force garbage collection after tearing down old nodes. This is to mitigate OOMs. You are already going to hitch because of the rebuild anyways.
	-Removed some dead/debug code that isnt needed.
