Add the "Edit:Protocols..." feature which currently only implements

the following:

It is now possible to enable/disable a particular protocol decoding
(i.e. the protocol dissector is void or not). When a protocol
is disabled, it is displayed as Data and of course, all linked
sub-protocols are disabled as well.

Disabling a protocol could be interesting:

- in case of buggy dissectors
- in case of wrong heuristics
- for performance reasons
- to decode the data as another protocol (TODO)

Currently (if I am not wrong), all dissectors but NFS can be disabled
(and dissectors that do not register protocols :-)

I do not like the way the RPC sub-dissectors are disabled (in the
sub-dissectors) since this could be done in the RPC dissector itself,
knowing the sub-protocol hfinfo entry (this is why, I've not modified
the NFS one yet).

Two functions are added in proto.c :

gboolean proto_is_protocol_enabled(int n);
void proto_set_decoding(int n, gboolean enabled);

and two MACROs which can be used in dissectors:

OLD_CHECK_DISPLAY_AS_DATA(index, pd, offset, fd, tree)
CHECK_DISPLAY_AS_DATA(index, tvb, pinfo, tree)

See also the XXX in proto_dlg.c and proto.c around the new functions.
