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.

Also did some whitespace cleanup, converting tabs to spaces since most of the file was spaced, not tabbed, and swapped the order that the lg and ig bits get added to the tree because I think it looks better reading bits left-to-right.
TODO: I'm not entirely sure what to do in capture_eth() if that invalid range is encountered, so for now I just added some #if 0'd code as a placeholder.

dissector tables with string keys. (Using _port can confuse people into
thinking they're intended solely for use with TCP/UDP/etc. ports when,
in fact, they work better for things such as Ethernet types, where the
binding of particular values to particular protocols are a lot
stronger.)

Patch utilizes techniques incorporated in the packet-ieee8023.c dissect_802_3()
routine to dynamically calculate the remaining payload length. This is then
compared to the length included in the CCSDS header.

(2) Duplicate 'blurb's are replaced with NULL
(3) Empty ("") 'blurb's are replaced with NULL
(4) BASE_NONE, NULL, 0x0 are used for 'display', 'strings' and 'bitmask' fields
for FT_NONE, FT_BYTES, FT_IPv4, FT_IPv6, FT_ABSOLUTE_TIME, FT_RELATIVE_TIME,
FT_PROTOCOL, FT_STRING and FT_STRINGZ field types
(5) Only allow non-zero value for 'display' if 'bitmask' is non-zero

CCSDS packets may reside within an 802.3 packet. This patch provides a way for
the CCSDS dissector to be called from the 802.3 dissector.

This patch adds a heuristic dissector to the ethernet trailer under the
keystring "eth.trailer". This allows for other protocol plugins which coopt
the ethernet trailer for their own devices to register for trailer traffic
without requiring any further changes to the executable.

1, eth.addr so people can see that this field exists (i think it is futile to use "hidden" fields and expect people to search through the infinitely long list of fields, better show everything and they will see themself what fuields they can filter on)
2, bit 0x01 of the first byte to show if it is Multi or Uni-cast
3, bit 0x02 of the first byte to show if it is a locally administrated address or not.
I do use the (to laymen) more descriptive names "factory default" instead of LocallyAdminAddr in the true_false string though.

It should not dump core as far as all my tests are concerned and Menu_Statistics/ProtocolHierStats work
It needs more testing and there might still be cases where it will crash that will need to be fixed but I feel it will be worth it since it will decrease the time to filter very large capture files dramatically.
Real significant performance boost for very large captures.
