[Joerg Mayer <jmayer@xxxxxxxxx>]

I have started to look a bit more methodically at things that should
have been declared static. The attached patch is the result of looking
at packet-a* to packet-ipsec.

The following files contain symbols that are not used outside but are
declared in a .h file:
  - packet-dcerpc-nt.c: dissect_dcerpc_uint8s dissect_ndr_nt_STRING_string
        prs_ntstatus prs_pop_ptr prs_push_ptr prs_uint32s
  - packet-dcerpc-samr.c: dissect_ndr_nt_SID_AND_ATTRIBUTES
  - packet-dcerpc-spoolss.c: ett_NOTIFY_OPTION_ARRAY
  - packet-dcerpc.c: dcerpc_tvb_get_ntohs

One file I haven't looked at in detail is packet-giop.c.

   Ciao

I found out that "pro" means "instead of" (as in proconsul). Now I know
what proactive means.

Changelog: <jmayer@xxxxxxxxx>
	Declare various variables static.
	Create packet-data.h for proto_data and use that in print.c
