net.stun: Fix parsing of STUN packets with 0-length attributes Not sure where the '20' came from. RFC 8489 defines attributes as simple TLVs, with the type+length header being always 16 bits (4 bytes). The branch for non-zero lengths already uses the correct header size.

  bosh = {
    tags = "mod_bosh";

  storage = {
    tags = "storage";
