    uaudp: fix buffer overrun while reading pref

    Drop the custom str_to_addr_ip, it overruns the buffer with at most 3
    bytes when an empty string is passed. Remove sizeof(guint8) while at it,
    the C standard requires this to be 1.

    Avoid overwriting uaudp.system_ip to avoid an invalid free of the
    preference.
