- create/use some extended value strings;
- remove unneeded #include files;
- remove unneeded variable initialization;

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.

ASCONF and ASCONF_ACK chunks have a "Sequence Number" field (RFC 5061, 4.1.1
and 4.1.2). The dissector wrongly calls it "Serial number". The attached patch
fixes this issue.

1. If there's no character encoding (ENC_ASCII, ...) specified
then use ENC_ASCII.
2. For all but FT_UINT_STRING, always use ENC_NA
(replacing any existing True/1/FALSE/0
/ENC_BIG_ENDIAN/ENC_LITTLE_ENDIAN).
svn path=/trunk/; revision=39426
Specifically: Replace FALSE|0 and TRUE|1 by ENC_BIG_ENDIAN|ENC_LITTLE_ENDIAN as
the encoding parameter for proto_tree_add_item() calls which directly reference
an item in hf[] which has a type of:
FT_BOOLEAN
FT_IPv4
FT_EUI64
FT_GUID
FT_UINT_STRING
Also: For type FT_ITv6 use ENC_NA. (This was missed in SVN #39260)

retranmissions (in COL_INFO). (Obviously this only works if TSN analysis is
enabled.)
This should make it more obvious to users which chunks are retransmissions and
will help avoid confusing the subdissector(s).

do the same as the non-tvb equivalents but take a TVB and an offset instead
of a pointer to an array of bytes.
Their purpose is to prevent (many) dissectors from doing:
ip_to_str(tvb_get_ptr(...)).
(About the names and the location: I like the names as they are but the names
imply that they should live in tvbuff.c. That would make some sense but
I didn't want to pull to_str.h into tvbuff.c...)

causes (should have been in rev 35366).
When generating TVB subsets, limit the subset's backing and reported lengths to
the (captured) TVB length and the reported TVB length, respectively.
This allows us to dissect most of the packet in
https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=5546
before asserting out.
It also yields similar better behavior when the capture is limited by a
snapshot length.
svn path=/trunk/; revision=35368
- "reported length" to be minimum of the entity's length (taken from the
packet) or the reported length of the TVB.
- "backing length" to be the minimum of the reported length (above) or the
(captured) length of the TVB.
This prevents tvb_new_subset() from generating an exception if the entity's
length (in the packet) is bogus (bigger than what's in the TVB) which allows
dissection to continue to a point where we can show the user what the problem
is.
When dissecting chunks, add an expert info if the item's length is bigger than
what was on the wire (the reported length). (The same could also be done for
parameters and error causes.)
This makes captures like that in https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=5546
easier to understand.
It also starts getting this dissector using the reported length instead of the
(captured) TVB length (there's more to be done with other tvb subsets).

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.)

subdissector the first fragment of a fragmented message so that an exception
in the first chunk doesn't abort dissection of subsquent chunks in the frame.
Restore pinfo->private_data after an exception was thrown by a subdissector.
This is necessary in case a subdissector had changed it but was unable to
restore it (due to the exception).

In some cases the usage may have been benign since it can be seen by code inspection that the maximum value of the end variable can't exceed the maximum value of the loop variable.
However, on general principles, all the usages have been fixed.
