<description>
A simple server that opens a UDP socket and returns connected [PacketPeerUDP] upon receiving new packets. See also [method PacketPeerUDP.connect_to_host].
After starting the server ([method listen]), you will need to [method poll] it at regular intervals (e.g. inside [method Node._process]) for it to process new packets, delivering them to the appropriate [PacketPeerUDP], and taking new connections.
Below a small example of how it can be used:
[codeblock]

Starts the server by opening a UDP socket listening on the given port. You can optionally specify a [code]bind_address[/code] to only listen for packets sent to that address. See also [method PacketPeerUDP.listen].

Call this method at regular intervals (e.g. inside [method Node._process]) to process new packets. And packet from known address/port pair will be delivered to the appropriate [PacketPeerUDP], any packet received from an unknown address/port pair will be added as a pending connection (see [method is_connection_available], [method take_connection]). The maximum number of pending connection is defined via [member max_pending_connections].

Stops the server, closing the UDP socket if open. Will not disconnect any connected [PacketPeerUDP].

Returns a [PacketPeerUDP] connected to the address/port combination of the first packet in queue. Will return [code]null[/code] if no packet is in queue. See also [method PacketPeerUDP.connect_to_host].

Define the maximum number of pending connections, during [method poll], any new pending connection exceeding that value will be automatically dropped. Setting this value to [code]0[/code] effectively prevents any new pending connection to be accepted (e.g. when all your players have connected).
