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.
