Always use STUN for hosting games using the lobby
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.

7bfcd9f78b Additional entropy when hashing match passwords.
The purpose of our client-side hashing for lobby game passwords is to
prevent malicious hosts from getting valuable passwords from clients
(e.g. accidentally typing their lobby password instead of the game, or
even their email password, etc).
However, the hashing was deterministic (and rather simple), making it
possible to compute rainbow tables and recover user passwords anyways.

By adding more variation, including some that cannot so easily be
controlled by the host (the client name), this becomes impractical. The
password hashing function used is rather fast, but given the base low
probability of mistypes, this seems fine.

e94faf7827 Don't hardcode the "0ad" resource into lobby XMPP & hosting
XMPP JID has a concept of 'resources', which can be used to
differentiate multiple clients of the same account.

We currently hardcode this 'resource' to '0ad' in two places:
- The 0 A.D. client always uses '0ad'
- The network code expects a host resource to be '0ad' when connecting.

As noted in 0fd8aa2a77#31215, it is less effort to store the JI
D directly. This patch does that. It also makes 0 A.D. use a different
resource each time.
Note that resources ought not contain particular information, as the
XMPP server is free to
 clobber it. I keep '0ad-' here for debug purposes.

This allows:
- multiple 0 A.D. instances to log on the lobby at the same time (not
massively useful, but good for debugging sometimes)
- hosting a game with a custom resource, which will potentially make it
easier to have dedi
cated servers on one account.

Note that hosting multiple games on one account is currently not
supported and will have weird behaviour on the lobbybots side. They
should be upgraded independently of this.

87fc52b780 MP: don't enforce game init attributes synchronization in PREGAME.
The NetServer stored a complete copy of the game Init Attributes, which
it sent to new clients on updates from the controller. This worked well,
but prevents incremental updates and other unrelated messages from being
sent.

This changes the system so that:
- in PREGAME state, the server does not update its copy of the game init
attributes
- the server forwards game setup messages from the controller to all
clients
- Joining clients get a full copy of the Settings, when joining, from
the controller (this is a js-driven behaviour - other situations might
not need do it).
- Make the StartNetworkGame message take a copy of the final init
attributes, to ensure synchronization (and simplify some logic).

In practice, this:
- makes it possible to send different types of gamesetup messages (this
introduces two: a regular update and the full 'initial-update' for new
clients).
- moves some C++ hardcoding into JS - here in essence the PREGAME server
state is now init-attributes-agnostic.
- does not change much for readiness control - the server already needed
to force a change at game start to set random elements.

Note that the loading page is currently still receiving the 'local' game
attributes, which assumes that all clients are correctly synchronized
(they should be).

113fefeeb7 Netcode: Identify controller client via a secret key
The 'controller' of an MP game (the host in general, though dedicated
servers would change that) is currently whoever first tells the server
that it is. This can be abused since it relies on trusting the clients.

This changes that logic: the server defines a 'controller secret', and
the first client to sent the correct controller secret is the
controller. This is safe assuming the secret is unknowable enough (the
current solution wouldn't pass strict cryptography tests, but it's
likely good enough).

Reverts 1a3fb29ff3, which introduced the 'trust the clients' mechanic,
as a change over 'the first local IP is controller'.

Necessary step towards dedicated server, if we want to use the regular
gamesetup (Refs #3556)

1a8de6d2b8 Hide ip and port from users until they want to join, add optional password
Current issue with the lobby, is that we make ips of hosts public for
anyone to read. This patch consists of 3 parts.
1.) Removing ips and ports from lobby javascript
2.) Removing need of script on the server to attach public ips to game
stanza by asking the host using xmppclient as proxy.
3.) Implementing password protected matches, to deny this information to
not trusted players.

Further description:
Do not send ports and stunip to the bots.

Removed from stanza.
Do not send ip to the lobby.

Removed from mapping gamelist from backend to gui (still on the backend
side, because it is done by script on 0ad server).
Get ip and ports on request when trying to connect.

On the host side, ask stun server what is host's public ip and remember
it.
On the client side, send iq through xmppclient to the hosting player and
ask for ip, port and if Stun is used, then if answer is success,
continue
   with connecting, else fail.
Add optional password for matches.

Add password required identifier to the stanza.
Allow host to setup password for the match. Hash it on the host side and
store inside Netserver. If no password is given, matches will behave
as it is not required.
On the client side, if password for the match is required, show
additional window before trying to connect and ask for password, then
hash it
and send with iq request for ip, port and stun.
Server will answer with ip, port and stun only if passwords matches,
else will asnwer with error string.
Some security:
Passwords are hashed before sending, so it is not easy to guess what
users typed. (per wraitii)
Hashes are using different salt as lobby hashing and not using usernames
as salt (as that is not doable), so they are different even typing the
same password as for the lobby account.
Client remembers which user was asked for connection data and iq's id of
request. If answer doesn't match these things, it is ignored. (thnx
user1)
Every request for connection data is logged with hostname of the
requester to the mainlog file (no ips).
If user gets iq to send connection data and is not hosting the match,
will respond with error string "not_server".
If server gets iq::result with connection data, request is ignored.

2d40068cd1 Thread the NetClient session.
This threads the netclient session, which avoids timeouts when the
main-thread is not polling (map creation, very long simulation frames).

Unlike the NetServer, which should be as independent as possible from
the main thread, the NetClient is fundamentally tied to the game thread.
Therefore, this only threads the session object.
To ensure good performance and ease-of-use, lock-free queues for
in/out-going messages are used.

This fixes artificial timeouts, while also improving actual ping reports
(since frame-time is no longer a factor).
It effectively reverts D1513/eda236522c and 2e7e1c0b2b, all hacks around
lag-timeouts (and bits of 1a3fb29ff3).

vector) where needed.
- Swap out some includes for forward declarations
- Clean up un-necessary boost includes in precompiled and other headers.
- Clean up precompiled headers, including fewer things.

25490bfec3 Improve JS Exception handling.
- Check for pending exceptions after function calls and script
executions.
- Call LOGERROR instead of JS_ReportError when there is a conversion
error in FromJSVal, since that can only be called from C++ (where JS
errors don't really make sense). Instead, C++ callers of FromJSVal
should handle the failure and, themselves, either report an error or
simply do something else.
- Wrap JS_ReportError since that makes updating it later easier.

This isn't a systematical fix since ToJSVal also ought return a boolean
for failures, and we probably should trigger errors instead of warnings
on 'implicit' conversions, rather a preparation diff.

ee0d204bf6 Wrap JSAutoRequest and replace usage of JSContext* with the wrapper.
JSAutoRequest is required before calling into most JSAPI methods, for GC
reasons.
Calling it is required and fragile as one must not forget.
Further, SM52 and later make manipulating JSContext* dangerous as that
can cross Compartment(Realm in SM68) barriers (and ScriptInterface now
matches a Compartment).

The solution to both problems is to avoid using JSContext* in 0 A.D.
itself. To achieve this, a Request class is introduced, and must be used
to access a JSContext* from a scriptInterface. Further, Request is
passed to other ScriptInterface functions isntead of JSContext*, making
it obvious that the caller has already called it, reducing errors and
redundant JSAutoRequest calls.
Only JSNative functions now get a naked JSContext* without protection,
but the likelihood of forgetting a request is lower since many
ScriptInterface functions now expect it.

JSContext* is directly passed to JSAPI functions only.

248a48d88a Major network cleanup. Patch by Imarok.
Access the server from the client only, not from the GUI (except for
autostarted games).
Thereby lay the foundation for clients to setup the game (refs #3806)
and dedicated hosting (refs #3556).
Doesn't transfer nor remove the SetTurnLength showcase from 0ebe3486b6.

This was SVN commit r18322.
