f34e11fabe Convert ethertype() function into a pure dissector. Bug 9454 (https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9454)
The main driving force for this was my new Decode As functionality (https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9450) that wants a dissector/subdissector table relationship for all dissectors wanting to use Decode As functionality.  The ethertype() function provides the value to the "ethertype" subdissector table, so I think it should be matched to a dissector.  Only odd side effect is the display filter of "ethertype" returns no packets because there is no "item" associated with the dissector.

b38ee917b1 Convert proto_tree_add_uint_format to proto_tree_add_uint_format_value if hf_ field name is the first part of the formatted string. This was done with a perl script on the dissectors directory (packet-*.c), followed by manual inspection of the output. The manual inspection yielded a few cases that really should have been proto_tree_add_uint or proto_tree_add_item, so I updated them accordingly.
The script didn't catch as many as I would have liked, but it's a start.

The most common (ab)use of proto_tree_add_uint_format was for appending strings to CRC/checksum values to note good or bad CRC/checksum.

6b629c4d92 Move show_exception() and show_reported_bounds_error() to
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.

f5ff1c5001 Do some cleanup related to the reversion of SVN #34848 donr in SVN #39100.
1. Revert SVN #35830 (See Bug #5645);

   http://anonsvn.wireshark.org/viewvc?revision=39100&view=revision

2. Restore 'col_set_str(pinfo->cinfo, COL_INFO, "Ethernet II");' just to
       be safe (altho it's possible that this line is not needed).

3. Remove several lines of no longer needed code.

2d99c2dbb4 Although technically not needed, for clarity, explicity catch invalid Ethernet frames, increment the "other" count and return. Previously, code execution would have fallen through to the ETHERNET_II case and capture_ethertype() would have incremented the "other" count.

3dd1b0c0de Based on Guy's suggestion from the user mailing list, dissect Ethernet frames with a type/len field in the range of 1501-1535 as invalid, and add an expert info to make it that much easier to find such invalid frames.
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.

a8bc4a0d13 Rename the routines that handle dissector tables with unsigned integer
keys to have _uint in their names, to match the routines that handle
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.)
