Tvbuffers changed to added the data source name,
GUI and printing code changed to support these changes
and display the multiple hex views.

Change them to use facilities in Ethereal that were probably not present
when they were originally written, e.g. routines to fetch 24-bit
integers and to dump a bunch of raw bytes in hex.
Redo them to extract data from the packet as they dissect it, rather
than extracting an entire data structure at once; that way, it may be
able to dissect a structure not all of which is in the packet.
Dissect a bit more of the type-of-service metrics etc. in OSPF packets.
Make "tvb_length_remaining()" return a "gint", not a "guint"; it returns
-1 if the offset is past the end of the tvbuff.
Add a "tvb_reported_length_remaining()" routine, similar to
"tvb_length_remaining()". Use it instead of just subtracting an offset
from "tvb_reported_length()".

NUL-terminated string, starting at a given offset. The size includes
the terminating NUL. If it doesn't find the terminating NUL, it throws
the appropriate exception, as either there's no terminating NUL in the
packet or there is but it's past the end of the captured data in the
packet.
Use that routine in the TFTP dissector. As it throws an exception if
the string isn't NUL-terminated, we can just use "%s" to print option
strings; we don't need to use "%.*s" with a string length.

of the search if the caller-supplied limit goes past the end of the
tvbuff - the limit should just be what remains in the tvbuff after the
specified starting offset.
In "tvb_find_line_end_unquoted()", after searching for the next
interesting character, check the value we got back from that search, in
"char_offset", not whatever happens to be in "cur_offset", to see if we
found a character.

ESIS dissectors.
Register the IP dissector and have dissectors that call it directly
(rather than through a port table) call it through a handle.
Add a routine "tvb_set_reported_length()" which a dissector can use if
it was handed a tvbuff that contains more data than is actually in its
part of the packet - for example, handing a padded Ethernet frame to IP;
the routine sets the reported length of the tvbuff (and also adjusts the
actual length, as appropriate). Then use it in IP.
Given that, "ethertype()" can determine how much of the Ethernet frame
was actually part of an IP datagram (and can do the same for other
protocols under Ethernet that use "tvb_set_reported_length()"; have it
return the actual length, and have "dissect_eth()" and "dissect_vlan()"
use that to mark trailer data in Ethernet II frames as well as in 802.3
frames.

tvbuff routines that a particular TVBUFF_REAL_DATA tvbuff is a "child"
of another tvbuff. This link is utilized during a tvb_free_chain(), so that
the child is freed when no longer necessary.

string formatter, like "format_text()", and, as "tvbuff.c" now calls it
(*vide infra*), we don't want to have to make "tvbuff.c" drag "packet.h"
in just to declare "bytes_to_str()". It's now declared in "strutil.h",
so include it in modules that use "bytes_to_str()" and weren't already
including it.
Add a "tvb_bytes_to_str()" wrapper that calls "tvb_get_ptr()" to get a
pointer to a chunk of N bytes at a given offset in a tvbuff and then
hands that chunk to "bytes_to_str()". Convert the code that was doing
that to use "tvb_bytes_to_str()" instead (which caught what I suspect is
a bug in the Q.2931 dissector, where it was handing an offset of 0 to
"tvb_get_ptr()" - a cut-and-pasteo, I think).
Tvbuffify the ARP dissector.

by itself as a line ending, as well as treating CR LF and LF as line
endings.
Tweak the Telnet dissector to treat LF and CR NUL as line endings, but
not to treat CR by itself as a line ending (that's not exactly what the
NVT specification in the Telnet RFC specifies, but the resulting output
may be a bit more readable that way).
svn path=/trunk/; revision=2613
Add "tvb_find_line_end_unquoted()" for the benefit of the SDP dissector;
get rid of "find_line_end_unquoted()" as nobody uses it any more.
Add "tvb_pbrk_guint8()" for the benefit of
"tvb_find_line_end_unquoted()"; it searches for any of a number of
characters, unlike "tvb_find_guint8()" which searches for only one.
svn path=/trunk/; revision=2595
Add "tvb_find_line_end()", to find a CR and/or LF-terminated line in a
tvbuff and return its length and the offset of the character after the
line end, for the use of those dissectors.
Add "tvb_strncaseeql()", which is like "tvb_strneql()" except that it
does a case-insensitive comparison.

the string rather than the offset of the end of the string, plus a patch
to "tvb_get_nstringz()" to treat the return value of "tvb_strnlen()" as
a length rather than an end offset.
