Guy Harris c8196a1d1c Tvbuffify the IP, ICMP, TCP, UDP, OSI CLNP, OSI COTP, OSI CLTP, and OSI
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.

Gilbert Ramirez 29a2973984 Add tvb_set_child_real_data_tvbuff(), which allows you to tell the
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.

Guy Harris 99c98f9e74 Move "bytes_to_str()" to "strutil.c" from "packet.c" - it's just a
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.

Guy Harris f8934eb9e7 Make "tvb_find_line_end()" and "tvb_find_line_end_unquoted()" treat CR
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).

Guy Harris b9d2dd7151 Make the string-to-compare-with arguments to "tvb_strneql()" and
"tvb_strncaseeql()" "const guint8 *", so that you can pass them pointers
to "const".

Guy Harris b63646ecc0 Allow "tvb_find_guint8()", "tvb_pbrk_guint8()", and "tvb_strnlen()" to
take -1 as a "maxlength" value, meaning "to the end of the tvbuff".

Guy Harris 07eb30403d Tvbuffify the SAP and SDP dissectors.
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.

Guy Harris 01a890cf95 Tvbuffify the HTTP, NNTP, RSH, RTSP, and Telnet dissectors.
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.

Guy Harris 1a793d05ee Patch from Heikki Vatiainen to make "tvb_strnlen()" return the length of
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.
