take a dissector handle as an argument, rather than a pointer to a
dissector function and a protocol ID. Associate dissector handles with
dissector table entries.

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.

structure, we may have to worry about it in more places than the places
that *used* to set "pi.len" and "pi.captured_len", so there's no point
in just saving and restoring it there. We'll remove those
saves/restores, and worry about saves and restores when we find a
problem.

structure, the check for a null tvbuff pointer in "alloc_field_info()",
and the "tvb_create_from_top()" macro; they're no longer needed, as
there's no non-tvbuffified dissector code remaining.

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.

source name from "pi.compat_top_tvb", which should always be set to the
tvbuff that refers to the data that old-style dissectors are currently
working on.
Arrange that it be so set in those dissectors that create alternate data
sources and call other dissectors, and also arrange that "pi.len" and
"pi.captured_len" be set appropriately as well.

respectively, not Q.931 and Q.2931, in Frame Relay.
When dissecting Q.933-style multiprotocol encapsulated Frame Relay
frames, use the "osinl" dissector table to check for OSI network layer
protocols, include the NLPID in the tvbuff you hand to
"dissector_try_port()" with that dissector table, and put the NLPID into
the protocol tree as an invisible item - the NLPID is considered part of
the PDU for those protocols, so you have to include it in the tvbuff,
and the dissector will put it into the protocol tree.
Also, make sure the top-level entry for the Frame Relay protocol
includes all the bytes preceding the payload, and none of the payload
bytes.
Export a routine to do Q.933-style dissection, and have the WCP
dissector call it, rather than duplicating that code in the WCP
dissector.
Don't register OSI network layer protocols with the "fr.ietf" dissector
table; it's now sufficient to register them with the "osinl" dissector
table, as the Frame Relay dissector now checks that.
Get rid of unnecessary checks for protocols being enabled (if the
dissector is always called through handles or dissector tables, the
common code for handles and dissector tables will do the checks for
you).
Get rid of some unnecessary #includes.
