Move dissectors to epan/dissectors directory.
Also move ncp222.py, x11-fields, process-x11-fields.pl,
make-reg-dotc, and make-reg-dotc.py.
Adjust #include lines in files that include packet-*.h
files.

There are multiple reasons for this: - * - The SCSI CDB is typically embedded inside the transport along with other - * header fields that have nothing to do with SCSI. So, it is required to be - * invoked on a embedded subset of the packet. - * - Originally, Ethereal couldn't do filtering on protocol trees that were not - * on the top level. - * - * There are four main routines that are provided: - * o dissect_scsi_cdb - invoked on receiving a SCSI Command - * void dissect_scsi_cdb (tvbuff_t *, packet_info *, proto_tree *, guint, - * guint); - * o dissect_scsi_payload - invoked to decode SCSI responses - * void dissect_scsi_payload (tvbuff_t *, packet_info *, proto_tree *, guint, - * gboolean, guint32); - * The final parameter is the length of the response field that is negotiated - * as part of the SCSI transport layer. If this is not tracked by the - * transport, it can be set to 0. - * o dissect_scsi_rsp - invoked to destroy the data structures associated with a - * SCSI task. - * void dissect_scsi_rsp (tvbuff_t *, packet_info *, proto_tree *); - * o dissect_scsi_snsinfo - invoked to decode the sense data provided in case of - * an error. - * void dissect_scsi_snsinfo (tvbuff_t *, packet_info *, proto_tree *, guint, - * guint); - * - * In addition to this, the other requirement made from the transport is to - * provide a unique way to determine a SCSI task. In Fibre Channel networks, - * this is the exchange ID pair alongwith the source/destination addresses; in - * iSCSI it is the initiator task tag along with the src/dst address and port - * numbers. This is to be provided to the SCSI decoder via the private_data - * field in the packet_info data structure. The private_data field is treated - * as a pointer to a "scsi_task_id_t" structure, containing a conversation - * ID (a number uniquely identifying a conversation between a particular - * initiator and target, e.g. between two Fibre Channel addresses or between - * two TCP address/port pairs for iSCSI or NDMP) and a task ID (a number - * uniquely identifying a task within that conversation). - * - * This decoder attempts to track the type of SCSI device based on the response - * to the Inquiry command. If the trace does not contain an Inquiry command, - * the decoding of the commands is done as per a user preference. Currently, - * only SBC (disks) and SSC (tapes) are the alternatives offered. The basic - * SCSI command set (SPC-2/3) is decoded for all SCSI devices. If there is a - * mixture of devices in the trace, some with Inquiry response and some - * without, the user preference is used only for those devices whose type the - * decoder has not been able to determine. - * - */ -#ifdef HAVE_CONFIG_H -# include "config.h" -#endif - -#include <glib.h> -#include <string.h> -#include <epan/strutil.h> -#include <epan/packet.h> -#include <epan/int-64bit.h> -#include "prefs.h" -#include "packet-scsi.h" - -static int proto_scsi = -1;
