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.

Apply rev 25869 to most of the rest of the TCP-desegmenting dissectors.
(The SSL dissector was already updated in one of two spots with bug 4535/rev
32456.)
A couple of the patches had to be manually applied.
From me: Fix the comments to match the change (including in the TCP and SSL
dissectors.)

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.)

The attached patch adds the missing decoded fields
by moving the proto_tree_add_item() call so that it
is no longer within an error handler and will be
called under normal circumstances (as well as error conditions.
From me: Apply the change to the ASN.1 source. Also some white space
indentation cleanup.

we're constructing a display filter, don't include the time zone,
otherwise do. Fixes bug 4756.

date as YYYY/DDD, where DDD is a 1-origin day of year. Move the formats
to a "time_fmt.h" file, included by the headers that use it. Have
abs_time_to_str() and abs_time_secs_to_str() take the date format value,
rather than a Boolean "show this as UTC" flag, as an argument. Document
the ABSOLUTE_TIME_ formats a bit better. Use that format in the CCSDS
and VCDU dissectors, rather than having those dissectors do the
formatting themselves.

for GNUTLS since they provide 32-bit and 64-bit Windows packages. We no
longer have winposixtype.h, so remove its #includes and add a ssize_t
typedef to config.h.win32.

ABSOLUTE_TIME_LOCAL or ABSOLUTE_TIME_UTC, indicating whether to display
the date/time in local time or UTC. (int)ABSOLUTE_TIME_LOCAL ==
(int)BASE_NONE, so there's no source or binary compatiblity issue,
although we might want to eliminate BASE_NONE at some point and have the
BASE_ values used with integral types start at 0, so that you can't
specify BASE_NONE for an integral field.

indicating whether the time should be shown as local time or UTC. For
now, always pass FALSE, meaning "show as local time".
Clean up some stuff in the SNMP dissector, use abs_time_secs_to_str()
for times with one-second resolution, and update a comment in various
macros in the WSP dissector, while we're at it.
