(ported 17f75903b029bbf01217153dc98009d305137c8f and 11ddcfa9a1f2311ec67377b76ed1160ef14b7f60)

(cherry picked from commit 7a05a8acf73ac0f012135339447c9a935e3b7939)

This reverts commit 82dbe95e.

Got_AddPlayer: check that I_GetNodeAddress(node) is non-NULL before using strcpy to copy it to the playeraddress array

This avoids some desynch issues and is simpler to handle.
Those packets are always big anyway, so the difference is irrelevant.

This code uses a custom packet acknowledgement system,
which is more suited for file transfer and does not suffer from
the small sender window used by the default acknowledgement system

This took fucking ages and it still fails sometimes in edge cases, but I
don't give a FUCK right now.

Cvars:

http_masterserver is the url to the master server's API.
masterserver_token may be an authentication token.
