SPC-3 defines SERVICE ACTION IN(12), SERVICE_ACTION OUT(12),
SERVICE ACTION OUT(16), and SERVICE ACTION BIDIRECTIONAL.
And READ MEDIA SERIAL NUMBER has long since been deprecated.
So update callers to refer to the new cdb name.

SPC-3 defines SERVICE ACTION IN(12) and SERVICE ACTION IN(16).
So rename SERVICE_ACTION_IN to SERVICE_ACTION_IN_16 to be
consistent with SPC and to allow for better distinction.

The function handler should be unregistered when the plugin is unloaded
otherwise it'll try to access invalid memory.

The scsi and cfg80211 plugins cast between unsigned long long and
pointers, which is problematic for architectures where unsigned long
long is wider than the native pointer size:
linux/tools/lib/traceevent/plugin_scsi.c: In function ‘process_scsi_trace_parse_cdb’:
linux/tools/lib/traceevent/plugin_scsi.c:408:26: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
scsi_trace_parse_cdb(s, (unsigned char *) args[1], args[2]);
linux/tools/lib/traceevent/plugin_cfg80211.c: In function ‘process___le16_to_cpup’:
linux/tools/lib/traceevent/plugin_cfg80211.c:11:18: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
uint16_t *val = (uint16_t *) args[0];
This patch adds an intermediate cast to unsigned long, silencing the
warning.

Adding scsi plugin.
This plugin adds fields resolving functions for following tracepoint
events:
scsi:scsi_dispatch_cmd_start
scsi:scsi_dispatch_cmd_error
scsi:scsi_dispatch_cmd_done
scsi:scsi_dispatch_cmd_timeout
The diff of 'perf script' output generated by old and new code:
(data was generated by 'perf record -e 'scsi:scsi_dispatch_cmd*' -a)

NOTE I couldn't generate scsi_dispatch_cmd_timeout tracepoint,
but it's similar to the rest, so I believe it's ok.
