Add dissector for PAPI (Aruba AP Control Protocol), used by Aruba WLAN
Controller).
There is no documentation on this protocol, the dissector is based on my
analysis ...
There is also an experimental "debug dissector" (not enable by default) for
dissecting the rest of data.
Changes by me:
- make it a new-style dissector
- change the name of the "debug" preference
- other minor changes
