Guy Harris 8ed7a73e22 Fix a bunch of warnings.
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.

Jeff Morriss aa5d9d78dd From Robert Bullen via https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=7683 :
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.

Pascal Quantin 74a43c3ada Fix https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=7622 :
Fix dissection of a few TDS fields (line number in ERR and MSG token, user type in RESULTS token, row count in DONE token) when the TDS version is >= 7.2.
Add a mechanism to memorize the TDS 7.X version in the conversation based on the TDS version found in LOGIN ACK token. This version is used for dissection when a TDS version is not set in preferences (TDS protocol type set to "not specified").

Apply rev 25869 to most of the rest of the TCP-desegmenting dissectors.

From me: Fix the comments to match the change (including in the TCP and SSL
dissectors.)

Guy Harris a8bc4a0d13 Rename the routines that handle dissector tables with unsigned integer
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.)

Jeff Morriss 1b04b1b765 From Emil Wojak via https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=5391 :
I'd like to share my enhancements to the TDS dissector with everyone.
The list of improvements follows:
- nearly complete dissection of RPC calls,
- detection and dissection of the ALL_HEADERS rule,
- corrected some existing proto_tree fields to support filters,
- other minor fixes where the interpretation of data conflicted with the
  official documentation from MS.

I tested the new code on a variety of different TDS captures with many diverse
RPC calls. The code compiles and works on 32-bit Linux, I didn't check those
changes on other platforms though.

From me:

- terminate all value_strings
- change ++*offset to *offset += 1 (I think that's more readable)
- replace all the dissector assertions which could be caused by malformed
  packets with expert infos
- Don't throw ReportedBoundsError when the packets have unexpected data in
  them, just report an expert info and continue on
