The UPnP implementation included a combination of two subtle bugs, which
resulted in failure to create port forwardings every time after the
first one.
When using UPnP, the internet gateway to create the port forwardings at
needs to discovered. As that takes a while, the its root descriptor URL
was supposed to be cached after successful discovery in the user config
in "network.upnprootdescurl". However, instead of caching the root
descriptor URL, the control URL got cached. That caused following
requests to the root descriptor URL to fail, as they ended up at the
control URL instead. As such requests might also fail when the network
topology changed, the code was supposed to fall back to discovering the
internet gateway again when the cached one didn't work. However, due to
the inner workings of miniupnpc the request using the cached root
descriptor URL didn't result in an error, so the new discovery was never
triggered. As the wrong value was persisted in the user config there was
also no way to get out of this situation again.
This commit fixes both of these bugs.
As far as I can tell these bugs existed since the introduction of the
caching of the root descriptor URL in 0ba25e9968, which means creating
port forwardings using UPnP has been broken since Alpha 15.
When adding a port forwarding via UPnP, pyrogenesis first needs to
discover the internet gateway to create the forwarding at. To do so, it
utilizes miniupnpc to send an SSDP request and waits 10 seconds until it
processes the responses and continues to add the port forwarding.
As that happens asynchronously it means if players hosting games rely on
UPnP for port forwarding and if their pyrogenesis instance doesn't have
the address of their internet gateway cached, it takes more than 10
seconds after starting to host a game, before players can join. However,
waiting for 10 seconds is completely unnecessary, because the internet
gateway responds immediately to the SSDP request. Therefore, this commit
reduces the time to wait for responses from 10 seconds to 2 seconds,
which is the timeout miniupnpc uses internally as well, when discovering
internet gateways.
Up to know the UPnP logic ignored the port a user was hosting a game on
and always added a port forwarding for the default port UDP 20595. This
commit fixes that, so a port forwarding is added for the actual port a
game is hosted on.
This makes using STUN mandatory for games hosted using the multiplayer
lobby. The motivation for that is a reduction in complexity, because
right now if STUN is disabled we use a home-grown STUN-like logic, which
got implemented before Pyrogenesis got STUN support.
That home-grown logic relies on a custom ejabberd module (mod_ipstamp),
which inserts the external IP-address of a host in the response messages
when a host registers a game. Originally mod_ipstamp was also used to
inform all potential players of a hosts IP-address, however that has
already been removed to let hosts to only share their IP-address with
players actually joining their game.
Removing the home-grown logic and instead always relying on STUN removes
complexity in Pyrogenesis and the lobby server and also eases hosting
games for players, as they don't have to figure out anymore whether they
need to enable STUN or not.
These changes shouldn't negatively impact the ability of Pyrogenesis to
handle different types of NAT or broken networks. There is one
difference though: While the custom logic using mod_ipstamp utilized TCP
as transport protocol, the STUN implementation in Pyrogenesis currently
uses UDP. That doesn't allow hosts with UDP-connectivity issues to
resolve their external IP-address anymore, however without
UDP-connectivity they aren't able to successfully host games anyway, as
the actual game updates are transferred using UDP as well.
The current code could end up with savegameID being undefined, false, a filename string, or null depending on the code path taken.

Fix `NetServerTurnManager` from pausing the simulation forever after a
client sent a bad hash to it and disconnects before the bad hash has
been processed.
A client that sends a wrong simulation hash to the `NetServer` and
disconnects before the server compares that hash causes a message box to
appear and the game to be paused forever.
94e5d88169 introduced the bug by missing to delete `m_ClientStateHashes
upon `UninitialiseClient.
This causes `m_ClientData[hashPair.first].isOOS = true` to insert a
client with blank values that the `NetServerTurnManager` will wait
forever and hence the message box about an OOS with no players being OOS
is shown (the playername is emptystring).
5ebf2020b0 exposed the bug by making observers able to lag behind,
providing a longe enough timeframe for this to occur.
Fix:
Deleting `m_ClientStateHashes` upon disconnect solves the broken
message box and the pausing.
This patch addresses issues concerning a1796ed71f:
Allow for a more elegant implementation of observer flares.
And still display flares even if the sender is lagging behind:
Split off flares from simulation commands.
Remove the new, problematic 'observer commands' entirely.
Provide an engine function 'SendNetworkFlare' to the JS interface.
-> which sets off the (pretty ordinary) transmission process.
Add a new type of net messages exclusively for flares
-> contains the flare's position and its sender's GUID.
This replaces all links pointing to trac with their corresponding links
to gitea. Also replace http with https while at it.

To disable tests we carry a patch which allows disabling test by
appending DISABLED to the test function name. Instead just do as
upstream says and prepend the test function so it won't be recognized as
a test any longer.
The docs suggest to prepend x but anything will do. Continue to use
DISABLED_ but as prefix which is actually already in use in one case.

The user doesn't have to fiddle with `std::shared_ptr`.
And two (more unrelated) things: use `std::unordered_map`, use a
`std::find_if` in the callback.

The `StateSet` is only used to check if a state is valid. That's useless
since it wouldn't be found in the `TransitionMap` - With the same
outcome.
