implicitly by the #define name and string they were defined to; not all
UATs neatly fit into any of the categories, so some of them were put
into categories that weren't obviously correct for them, and one - the
display filter macro UAT - wasn't put into any category at all (which
caused crashes when editing them, as the GUI code that handled UAT
changes from a dialog assumed the category field was non-null).
The category was, in practice, used only to decide, in the
aforementioned GUI code, whether the packet summary pane needed to be
updated or not. It also offered no option of "don't update the packet
summary pane *and* don't redissect anything", which is what would be
appropriate for the display filter macro UAT.
Replace the category with a set of fields indicating what the UAT
affects; we currently offer "dissection", which applies to most UATs
(any UAT in libwireshark presumably affects dissection at a minimum) and
"the set of named fields that exist". Changing any UAT that affects
dissection requires a redissection; changing any UAT that affects the
set of named fields that exist requires a redissection *and* rebuilding
the packet summary pane.
Perhaps we also need "filtering", so that if you change a display filter
macro, we re-filter, in case the display is currently filtered with a
display filter that uses a macro that changed.

1. If there's no character encoding (ENC_ASCII, ...) specified
then use ENC_ASCII.
2. Always use ENC_NA
(replacing any existing True/1/FALSE/0
/ENC_BIG_ENDIAN/ENC_LITTLE_ENDIAN).
svn path=/trunk/; revision=39428
Specifically: Replace FALSE|0 and TRUE|1 by ENC_BIG_ENDIAN|ENC_LITTLE_ENDIAN as
the encoding parameter for proto_tree_add_item() calls which directly reference
an item in hf[] which has a type of:
FT_BOOLEAN
FT_IPv4
FT_EUI64
FT_GUID
FT_UINT_STRING
Also: For type FT_IPv6 use ENC_NA. (This was missed in SVN #39260)
svn path=/trunk/; revision=39332
FT_NONE
FT_BYTES
FT_IPV6
FT_IPXNET
FT_OID
Note: Encoding field set to ENC_NA only if the field was previously TRUE|FALSE|1|0|ENC_LITTLE_ENDIAN|ENC_BIG_ENDIAN

When Wireshark attempts to read an SNMP packet with a variable-bindings item
with an OID containing an index string which includes an entry of type
"Unsigned32", Wireshark will stop dissecting the packet at this index entry and
end with the error:
[Dissector bug, protocol SNMP: proto.c:2761: failed assertion
"DISSECTOR_ASSERT_NOT_REACHED"]

Coverity sees that two calls to tvb_length_remaining() with an offset
of 0 may return -1 (for an "out of bounds" condition), which would lead
to an assignment of -1 to an unsigned variable and then passing it
to functions further down that cannot accept negative values.
Use tvb_ensure_length_remaining() to throw an exception in a case of
out of bounds access (though unlikely with an offset of 0) instead of
tvb_length_remaining(), which would return -1.
