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.

The primary header in bundle protocol contains some offset values(destination
scheme offset, destination ssp offset, source scheme offset, source ssp offset,
etc). These are the offsets within the dictionary if the length of the
dictionary length is greater than 0. But if the dictionary length is 0, then
these offset refer to node number and service number respectively(according to
compressed bundle header encoding). For example if destination scheme offset is
2 and the destination ssp offset is 1, then the destination
EID(<node_number>.<service_number>) is 2.1.
Currently the dtn dissector will consider these offsets to be actual offsets in
the dictionary even if the dictionary length is 0. So the values for the
EID's(destination, source, report, custodian) and their schemes are junk
values. For example if the destination scheme offset is 2 and the destination
ssp offset is 1 and the dictionary length is 0(which means the dictionary is
empty), then the destination scheme is 2 bytes after the beginning of the
metadata block(field after dictionary) and destination is 1 byte after the
beginning of the metadata block.

display_metadata_block() return 0 (meaning they failed to decode something and
the offset was not incremented) rather than checking if the resulting offset
is 0.
This fixes the infinite loop reported in:

SDNVs are theoretically unlimited in size. The value of most SDNVs in the
Bundle Protocol is practically limited to far less than a 32 bit number. The
initial dissector included only 1 SDNV evaluation routine which returned a 32
bit number. SDNV fields that evaluated to greater than a 32 bit number were
considered in error. One BP implementation chose to add some syntax to one of
the SDNV fields that extends it to more than 32 bits. The patch included here
adds an evaluation routine that will return a 64 bit number. That routine is
called to evaluate the field where it makes sense to have a value in excess of
32 bits.

Within the attached diff file are two source files, packet-dtn.h and
packet-dtn.c. Their function is to decode Bundle Protocol PDUs sent using the
UDP or TCP Convergence Layers. These protocols have been released by the
Internet Research Task Force and are described in RFC 4838 and RFC 5050.
