d783811c05 Reset needs_hole_punch when forcing server refresh.
This fixes #1 where servers requiring hole punch would time out from
the leader board after several hours when the server refresh triggers.
Besides, it's also possible the server no longer needs hole punching.

3cb43a5e5f Fix hole punch parsing with no port.
If the port is the default port we won't include the :port part of
the server address. In this case we must assume the default port.
This should fix clients being unable to connect to servers when they
run on the default port and require hole punch assistance.

0777aac061 Add new request type for HOLE_PUNCH_ALL.
In the setup tool when querying all servers from the master server, we also
need to hole punch all servers which need it. Rather than doing this with
many individual hole punch requests to the master server, add a single new
message type to hole punch all servers.

This could have been done as part of the normal query request handling,
automatically hole punching all servers unrequested by the client.
However, clients need to hole punch again when connecting and older clients
do not know how to do this. Separating out the functionality means that
hole punching will only be performed for newer clients which know about it.

9dca3ddca1 Send hole punch requests when adding servers.
If a server is behind a NAT gateway, we might not get a response when
we send it a query. However, a hole punch request may make it accessible.
After two seconds with no response, try a hole punch request and if we get
a reply, retry the request.

We keep state on which servers require hole punching and only allow hole
punch requests from clients if they are flagged as such.

This got changed by mistake.

4d767457df Add hole punch forwarding to master server.
If a server is behind a NAT gateway or firewall its UDP port may be
accessible to the master server but not to other clients. For some types
of gateway we can work around this by having the servers explicitly send
a packet to the client that is trying to connect to them ("hole punching").
The master server can serve as a trampoline to forward this request from
clients.

This is the initial master server-side part of implementing
chocolate-doom/chocolate-doom#469.

For testing the server may be running on a different port.

4c7861b2e0 Make master server work with Python 3.
As part of this, perform the `from __future__` imports so that as much
as possible resembles Python 3 even if we are running with Python 2.

a7f9439578 Report server age as integer.
This reduces the metadata response size slightly as we no longer need
to return a number of decimal points.

65704ad398 Correctly handle UTF-8 server names.
This fixes a problem where the page does not display properly if a
server name contains a non-ASCII character (see discussion on
chocolate-doom/chocolate-doom#229).

from start messages. Include millisecond precision in the time fields of
the messages for extra accuracy. Log nonce values and demo hashes.
