Adds a heur_dissector_delete() function to allow heuristic dissectors to be
dynamically disabled based upon, for example, preference settings.

Fix compilation failures when building wireshark-0.99.6-SVN-21916 on an
x86_64-unknown-linux-gnu target with gcc version 4.1.2 20070403 (Red Hat
4.1.2-8).
The failures fall into two categories:
(1) Casts between pointers and 32-bit integers without an intermediary cast
via 'long' or 'unsigned long'. This results in a compiler warning complaining
about casts between a pointer and an integer of a different size.
(2) Passing values to "%lld" or similar printf-style format options that the
compiler thinks are a different size. Such values need to be cast to 'long
long' or 'unsigned long long'.

--enable-extra-gcc-checks set.
If we turn on -pedantic, try turning on -Wno-long-long as well, so that
it's not *so* pedantic that it rejects the 64-bit integral data types
that we explicitly require.
Constify a bunch of stuff, and make some other changes, to get rid of
warnings.
Clean up some indentation.

- asn dissectors : libasndissectors.la
- pidl dissectors : libpidldissectors.la
- normal dissectors : libdissectors.la *and* libcleandissectors.la. I
separated it in two libraries temporarily. The source files used to build
libcleandissectors.la do not generate warning anymore and the -Werror is used
to compile them. If we patch a dissector and it doesn't generate warning
anymore, we have to move the filename dissector from DISSECTOR_SRC to
CLEAN_DISSECTOR_SRC in epan/dissectors/Makefile.common.
If you want to define specific cflags for one library type, let's say pidl, you
may define libpidldissectors_la_CFLAGS.

add sccp_info to struct _packet_info (Sorry but the way private_data works and the fact that TCAP uses it and BSSAP/RANAP can be tunnelled on GSMMAP over TCAP makes it impossible to avoid)
SCCP
- Have SCCP to have a TAP,
- Fix associations so that every message belongs to the association.
- Export message type values so that they can be used by a tap listener
RANAP
- Have RANAP information attached to the sccp_info
BSSAP + GSM_A
- Have DTAP, BSSMAP and BSSAP info attached to the sccp_info

use this field in the policy handle helper to indicate not only which frames the handle was opened/close in but also the name of the function that opened it.
eventually, when other pidl support infrastructure is developed it would be nice if this could be expanded to also contain the name of the object/handle opened.

I've just had a bug in one of our private dissectors which meant
that the handle passed to call_dissector was null. This seemed to give
varying behavior - on some Windows installations it hit wireshark's
in-built exception handling, and displayed that the dissector had an
error (correct), but on some installations it just crashed wireshark
(not helpful). I _think_ the difference was whether MSVC was installed
or not, but on a sample of only 3 machines.
Should call_dissector include explicit null handle checks, and if so,
should it:-
a) g_assert - the simple patch attached
b) fallback to doing a data decode (as disabled protocols do)
c) try to invoke the wireshark exception handling for the packet
Or is the correct answer none of the above - the exception handler
should already cope ?

04-stream.diff
A simplified packet reassembly API built on top of fragment_add_seq_next for
reassembling fragments that are delivered in-order, where fragments are
identified by a framenum and an offset into that frame. Streams are attached
to a conversation or a circuit and are unidirectional.

and that extract IPv6 addresses into a "struct e_in6_addr", with
tvb_get_ipv4() and tvb_get_ipv6() calls - except for some that we
remove, by using proto_tree_add_item(), rather than replacing.
Have epan/tvbuff.h include epan/ipv6-utils.h, to define "struct
e_in6_addr" (not necessary to declare the tvbuff routines, but including
it there means "struct e_in6_addr" is guaranteed to be defined before
those declarations, so we don't get compiler complaints if we define it
*after* those declarations).

so instead for g-alloc and g_free data
just use ep_alloc() that is automatically freed instead.
this also gets rid of one more GMemChunk

This is very naughty and will cause problems when we have assigned a dissector to a dynamic port using conversation_set_dissector().
To make ethereal handle this case I have changed the try_conversation_dissector() to allow it to fail and return 0, meaning yes there is indeed a protocol registered for this conversation but that protocol rejected this packet.
(which only happens for "new" style dissectors, "old" style dissectors will never reject a packet that way)
When this happens the decode_udp_port() helper will still allow other dissectors to be tried, in the hope that the conversation is now used for some other protocol and thus someone else might be able to decode the packet.
Update SNMP and TFTP dissectors to check that even if there already is a conversation but that conversation does NOT have snmp/tftp registered as the dissector for it, then create a new conversation anyway and attach the proper dissector.
Since ethereal keeps track of which frame number a conversation started in, this actually works really well.

structures allocated by a dissection. Currently, it's the same as
"init_dissection()", but they should be split with "init_dissection()"
allocating the initial data structures and "cleanup_dissection()"
freeing them and *not* reallocating the initial data structures.
Use "cleanup_dissection()" in "cf_close()" to make it easier to find leaks.

they have LF at the end of the line on UN*X and CR/LF on Windows;
hopefully this means that if a CR/LF version is checked in on Windows,
the CRs will be stripped so that they show up only when checked out on
Windows, not on UN*X.

(and the fact that nbss does not register its conversation)
this caused WANT_PDU_TRACKING to be decremented multiple times between
the dissectors
and thus ethereal could no longer reliably spot SMB PDUs that started in the middle of a tcp segment (unless we do reassembly which we dont do unless we have to since it eats soo many resources)
FIX so that ethereal once again can spot SMB (and other) protocol PDUs that start in the middle of a segment.
