From Mathias Guettler

dissector for ISO 10747 Inter Domain Routing Protocol
https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=8562

from me:
check for negative return value of tvb_reported_length_remaining()
remove unused hf entries
add modelines
don't initialise variables unless it's necessary
make idrp a new-style dissector
