android adhoc socket error binding port

[AdamN]

Well you can always add a constant number to the actual port number used by the games (to remap it) whenever a socket trying to connects or listens to a certain port (as a PPSSPP-specific multiplayer-mode).
This will prevent the game using privileged ports but making PPSSPP to be incompatible with real PSP or other emulators, but at least PPSSPP vs PPSSPP should works.
