Laurent Deniel d896d69930 SNMP dissector enhancements:
- display OID in info column

- preference added to disable such a display

- add new function new_format_oid to retrieve both
  decoded and non decoded OID strings

- add OID display filter for both decoded and non decoded strings

- add Error Status display filter

Guy Harris ae1ebc09da Don't include the header file to get the SNMP version unless we're
building with an SNMP library.

If we have Net-SNMP, include <net-snmp/version.h>, not
<ucd-snmp/version.h>.

Don't include any of the SNMP headers unless HAVE_SOME_SNMP is defined.

Include <net-snmp/config_api.h> if we have Net-SNMP, to declare
"read_premib_configs()" and "read_configs()".

Supply the include directories for Net-SNMP in the Makefile.nmake for
GTK 1.2 and GTK 2.

Guy Harris cc8a765d8e From Wes Hardaker:
Define HAVE_SOME_SNMP if either HAVE_UCD_SNMP or HAVE_NET_SNMP
	is defined, and use HAVE_SOME_SNMP, rather than HAVE_UCD_SNMP,
	in most places when testing whether we have an SNMP library or
	not.

	Be more selective when including Net-SNMP header files.

Fix up {gtk,gtk2}/main.c to do the same SNMP stuff that tethereal.c
does - including the MIB stuff that gtk/main.c was doing but gtk2/main.c
wasn't doing.

Fix the copyright date in gtk/main.c.

Guy Harris d50103f67f Use the "sprint_realloc_" routines in UCD SNMP 4.2.2 and later, rather
than the "sprint_" routines in UCD and CMU SNMP; the latter routines
have no bounds checking, and if you use them you cannot protect against
buffer overflows.

As we now require UCD SNMP 4.2.2 or later:

	1) we no longer need code to support CMU SNMP;

	2) we no longer need code to work around problems with UCD SNMP
	   4.1.1;

and, as we no longer use the "sprint_" routines, we no longer need code
to work around the changed API and ABI of those routines in some
nonstandard versions of the UCD SNMP library.

Guy Harris d8a08e186c Add a routine to "asn1.c" to translate ASN1_ERR_ values to strings. Use
that in the SNMP dissector.

Check the return values of ASN.1 routines in the LDAP dissector, and
have all the subroutines in that disesctor that can return error
indications return ASN1_ERR_ values.

Have the routines that can supply a pointer to a newly-created
protocol-tree item use the right type for items ("proto_item *", not
"proto_tree *", even though they are, at least currently, typedefs for
the same type), and use "proto_item" for the type of the item a pointer
to which is passed to those routines.

Before calling those routines, set the item pointer to null, in case the
routine fails.

Don't check the return value of "parse_filter_strings()" against -1 -
that routine can't return -1.

Guy Harris eb2d6593dc Replace a bunch of "tvb_length()" and "tvb_length_remaining()" calls in
arguments to "proto_tree_add_text()", and to "proto_tree_add_XXX()" calls
that add FT_NONE or FT_PROTO items to the protocol tree, with -1.

Replace some calls to "tvb_length()" or "tvb_length_remaining()" with
calls to "tvb_reported_length()" and "tvb_reported_length_remaining()",
as those give the actual length of the data in the packet, not just the
data that happened to be captured.

Guy Harris ee5ca25d31 Include files from the "epan" directory and subdirectories thereof with
"epan/..." pathnames, so as to avoid collisions with header files in any
of the directories in which we look (e.g., "proto.h", as some other
package has its own "proto.h" file which it installs in the top-level
include directory).

Don't add "-I" flags to search "epan", as that's no longer necessary
(and we want includes of "epan" headers to fail if the "epan/" is left
out, so that we don't re-introduce includes lacking "epan/").

Guy Harris 23319ff023 Move the pointer to the "column_info" structure in the "frame_data"
structure to the "packet_info" structure; only stuff that's permanently
stored with each frame should be in the "frame_data" structure, and the
"column_info" structure is not guaranteed to hold the column values for
that frame at all times - it was only in the "frame_data" structure so
that it could be passed to dissectors, and, as all dissectors are now
passed a pointer to a "packet_info" structure, it could just as well be
put in the "packet_info" structure.

That saves memory, by shrinking the "frame_data" structure (there's one
of those per frame), and also lets us clean up the code a bit.

Guy Harris bced8711f6 Make "dissector_add()", "dissector_delete()", and "dissector_change()"

Guy Harris 07b2709f8a Change "conversation_set_dissector()" to take a dissector handle, rather
than a pointer to a dissector function, as an argument.

This means that the conversation dissector is called through
"call_dissector()", so the dissector itself doesn't have to worry about
checking whether the protocol is enabled or setting
"pinfo->current_proto", so get rid of the code that does that in
conversation dissectors.  Also, make the conversation dissectors static.

Get rid of some direct calls to dissectors; replace them with calls
through handles, and, again, get rid of code to check whether a protocol
is enabled and set "pinfo->current_proto" where that code isn't needed.
Make those dissectors static if they aren't already static.

Add a routine "create_dissector_handle()" to create a dissector handle
without registering it by name, if the dissector isn't used outside the
module in which it's defined.

Guy Harris 3388bde488 Instead of having a single datum attached to a conversation, have a list
of protocol-id-plus-datum pairs, so that multiple protocols can attach
information to the same conversation.

Dissectors that attach information to a conversation should not assume
that if they find a conversation it has one of its data attached to it;
the conversation might've been created by another dissector.

Guy Harris 3c7b6471e3 Rename the arguments and flags for the conversation routines, so as not
to imply that

	1) conversations have source and destination addresses and ports
	   - they don't (if they did, they'd be monologues, not
	   conversations), they just have two address/port pairs for the
	   two endpoints, with one or more of the address or port in the
	   second pair possibly being wildcarded;

	2) the first and second address or port argument to
	   "find_conversation()" or "try_conversation_dissector()" have
	   anything to do with the first or second address/port pair in
	   a conversation - they don't, the two arguments to those
	   routines are matched against *both* address/port pairs for a
	   conversation;

as otherwise people might think that they need to add flags to wildcard
the first arguments "conversation_new()" or "find_conversation()" (they
don't, they just have to pass the non-wildcarded address/port first and
then pass the wildcarded one, even if that means passing the destination
first and source second).

Guy Harris 1bfd09545e At least with UCD SNMP 4.1.2, you can safely pass to "sprint_value()" a
variable with a null pointer-to-value and a zero length, so we don't
need to protect the assignment to "variable.val.string" with
"SAFE_STRING()" - and doing so causes complaints from the compiler about
assigning a pointer to a "const gchar" to the non-const pointer
"variable.val.string".
