for ease of use from java. Since libbluetooth stupidly and
unrepentantly redefines uuid_t, add a new file/function to call
libuuid without having to pull its definitions into the bt code. This
code compiles but is completely untested: I don't quite remember how
to play games via BT on Linux and at any rate will need an always-on
listener like the one I'm adding to the Android client.
