Add fields for the absolute time stamp (and another field for a presence

This lets us remove the field for the packet encapsulation in the

I have traces where IP reassembly gets confused by multiple frames from
different VLANS and ends up adding fragments from differet messages
togeter after IP Identification is reused.
I think VLAN ID could be useful in other places too to aviliate duplicate
packet detection. Making this a separate patch while testing the usage.

The only remaining explicit user of the packet_info members is the NTLMSSP dissector. However, there may be "hidden" use of it in the spnego dissector passing between ASN.1 functions.
Someone more familiar with the protocols could possibly trim some of the "extra copies" between packet_info and gssapi_encrypt_info_t structure, but I went the "better safe than sorry" route.

This adds the ability for Lua scripts to register heuristic dissectors
for any protocol that has registered a heuristic dissector list, such
as UDP, TCP, and ~50 others. The Lua function can also establish a
conversation tied to its Proto dissector, to avoid having to check the
heuristics for the same flow. The example dissector in the testsuite
has also been enhanced to include a heuristic dissector, to verify
the functionality and provide an example implementation.

I'm not sold on the name or module the proto_data functions live in, but I believe the function arguments are solid and gives us the most flexibility for the future. And search/replace of a function name is easy enough to do.
The big driving force for getting this in sooner rather than later is the saved memory on ethernet packets (and IP packets soon), that used to have file_scope() proto data when all it needed was packet_scope() data (technically packet_info->pool scoped), strictly for Decode As.
All dissectors that use p_add_proto_data() only for Decode As functionality have been converted to using packet_scope(). All other dissectors were converted to using file_scope() which was the original scope for "proto" data.

make Save-As/Displayed/All-Packets save not only the displayed packets but
also any other packets needed (e.g., for reassembly) to fully dissect the
displayed packets.
This works only for the "All packets" case; choosing only the Selected packet,
the Marked packets, or a range of packets would require actually storing which
packets depend on which (too much memory) or going through the packet list many
times (too slow). Also, this behavior is always the case: you can't save the
displayed packets without their dependencies (I don't see why this would be
desirable).
So far this is done for SCTP and things using the reassembly routines (TCP has
been tested).
The Win32 dialog was modified but hasn't been tested yet.
One confusing aspect of the UI is that the Displayed count in the Save-As
dialog does not match the number of displayed packets. (I tried renaming the
button "Displayed + Dependencies" but it looked too big.) The tooltip tries
to explain this and the fact that this works only in the All-Packets case;
suggestions for improvement are welcome.
Implementation details:
Dissectors (or the reassembly code) can list frames which were needed to
build the current frame's tree. If the current frame passes the display
filter then each listed frame is marked as "depended upon" (this takes up the
last free frame_data flag).
When performing a Save-As/Displayed/All-Packets then choose packets which
passed the dfilter _or_ are depended upon.
