be done on flows from one address to another; reassembly for protocols
running atop TCP should be done on flows from one TCP endpoint to
another.
We do this by:
adding "reassembly table" as a data structure;
associating hash tables for both in-progress reassemblies and
completed reassemblies with that data structure (currently, not
all reassemblies use the latter; they might keep completed
reassemblies in the first table);
having functions to create and destroy keys in that table;
offering standard routines for doing address-based and
address-and-port-based flow processing, so that dissectors not
needing their own specialized flow processing can just use them.
This fixes some mis-reassemblies of NIS YPSERV YPALL responses (where
the second YPALL response is processed as if it were a continuation of
a previous response between different endpoints, even though said
response is already reassembled), and also allows the DCE RPC-specific
stuff to be moved out of epan/reassembly.c into the DCE RPC dissector.

Cast away some implicit 64-bit-to-32-bit conversion errors due to use of
sizeof.
Cast away some implicit 64-bit-to-32-bit conversion errors due to use of
strtol() and strtoul().
Change some data types to avoid those implicit conversion warnings.
When assigning a constant to a float, make sure the constant isn't a
double, by appending "f" to the constant.
Constify a bunch of variables, parameters, and return values to
eliminate warnings due to strings being given const qualifiers. Cast
away those warnings in some cases where an API we don't control forces
us to do so.
Enable a bunch of additional warnings by default. Note why at least
some of the other warnings aren't enabled.
randpkt.c and text2pcap.c are used to build programs, so they don't need
to be in EXTRA_DIST.
If the user specifies --enable-warnings-as-errors, add -Werror *even if
the user specified --enable-extra-gcc-flags; assume they know what
they're doing and are willing to have the compile fail due to the extra
GCC warnings being treated as errors.

This patch will print the information if an
invalid string was entered. It would be better to have a button to click on in
the UAT dialog to show valid values, but I don't know how I could do that with
the UAT system. So I'm simply printing it now in the error dialog, which should
be good enough.

- revert incorrect replacement of FALSE by ENC_BIG_ENDIAN
done a while back (10 instances);
[The incorrect use of ENC_BIG_ENDIAN was benign since
ENC_BIG_ENDIAN is currently defined as 0x0000000];
- Remove unneeded #includes;
- whitespace (e.g., use consistent indentation).

The reassembled fragments tree in the Packet Details view is awesome, but it
lacks one thing: a field that exposes the reassembled data.
tcp.data already exists for exposing a single TCP segment's payload as a byte
array. It would be handy to have something similar for a single application
layer PDU when TCP segment reassembly is involved. I propose
tcp.reassembled.data, named and placed after the already existing field
tcp.reassembled.length.
My primary use case for this feature is outputting tcp.reassembled.data with
tshark for further processing with a script.
The attached patch implements this very feature. Because the reassembled
fragment tree code is general purpose, i.e. not specific to just TCP, any
dissector that relies upon it can add a similar field very cheaply. In that
vein I've also implemented ip.reassembled.data and ipv6.reassembled.data, which
expose reassembled fragment data as a single byte stream for IPv4 and IPv6,
respectively. All other protocols that use the reassembly code have been left
alone, other than inserting NULL into their initializer lists for the newly
introduced struct field reassemble.h:fragment_items.hf_reassembled_data.

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.

File name preferences are basically just string preferences except that the
GUI will present a "Browse" button that allows the user to go and find the
file s/he wants (rather than having to blindly type in the full path).

r40200 made ssl_parse()/dtls_parse() post-update-callbacks for those
dissector's UATs so that the dissector would be updated when the user changed
the UAT. (This allows SSL/DTLS keys to be taken into account without requiring
Wireshark to be restarted.)
But, those functions also update the UAT themselves if the old-style keys_list
preference is used, creating an infinite recursion.
Fix this by splitting the *_parse() functions into two: one for the UAT and one
for the old-style keys list.

(The explicit IV field in the application record doesn't exist when stream ciphers are used. But the original code handles it as if one-byte IV exists.)
