Centralize logic related to per-interface conversations, and expose it for use
by class-specific dissectors.
Class-specific descriptor dissectors also need to know the interface in whose
context they are called to work.
This is a prerequisite for a USB Video Class dissector, which needs to decode
many class-specific descriptors.

New dissector for the honeypot-feeds protocol.
From me: Misc. tweaks to expert info layout and remove a few unneeded initializers.

commented-out/#if-ed-out "Data1" field, as it's the same field.
Give the flags in that field names including "flags".
Shuffle the fields around to put "Flags" (a/k/a Data1) where Data1 was,
and put the bits in that field after it.
Update the URL for the spec at IBM.
Reformat the entries in hf_netb[] to use the same style.

A detailed diagnostic information contains either a SMS-SUBMIT-REPORT or a SMS-DELIVERY-REPORT. Set P2P direction accordingly.

epan/show_exception.c, as it's used outside
epan/dissectors/packet-frame.c. Update their callers to include
<epan/show_exception.h> to get their declaration.
Add a CATCH_NONFATAL_ERRORS macro that catches all exceptions that, if
there's more stuff in the packet to dissect after the dissector call
that threw the exception, doesn't mean you shouldn't go ahead and
dissect that stuff. Use it in all those cases, including ones where
BoundsError was inappropriately being caught (you want those passed up
to the top level, so that the packet is reported as having been cut
short in the capture process).
Add a CATCH_BOUNDS_ERRORS macro that catches all exceptions that
correspond to running past the end of the data for a tvbuff; use it
rather than explicitly catching those exceptions individually, and
rather than just catching all exceptions (the only place that
DissectorError should be caught, for example, is at the top level, so
dissector bugs show up in the protocol tree).
Don't catch and then immediately rethrow exceptions without doing
anything else; just let the exceptions go up to the final catcher.
Use show_exception() to report non-fatal errors, rather than doing it
yourself.
If a dissector is called from Lua, catch all non-fatal errors and use
show_exception() to report them rather than catching only
ReportedBoundsError and adding a proto_malformed item.
Don't catch exceptions when constructing a trailer tvbuff in
packet-ieee8023.c - just construct it after the payload has been
dissected, and let whatever exceptions that throws be handled at the top
level.
Avoid some TRY/CATCH/ENDTRY cases by using checks such as
tvb_bytes_exist() before even looking in the tvbuff.

put the length, identifier, and value as visible sub-items underneath
it. If the length is bad, add an expert info indication under the item
for the length, rather than using proto_malformed. Add checks for the
lengths of each type of subvector.
Add some more subvector types from IEEE 802.5-1998, and use the names
from that spec.

the compressed data, put the entries for particular parts of that data
under that entry, and, when we have a problem decompressing, add an
expert info item to that entry, rather than just adding text or using
proto_malformed. Do so for *all* decompression problems; in particular,
check for decompressed_entry() returning NULL, which it can do.
tvb_new_child_real_data() won't throw an exception, so don't bother
checking for that.
If, after the first pass, we can't find the uncompressed data for a
frame, report it as a dissector bug.
Check whether we have room for a byte in the uncompressed data buffer
*before* copying it.
Other cleanups.

way we don't keep two copies of the fragments in memory until the file is
closed.
wmem is probably a better alternative to this.
