Had a confusing decoded trace record:
Timestamp : ...
Area : SCSI
...
Tag : rsl_err
...
SCSI result : 0x00000002
SCSI opcode : 1a...
FCP rsp inf cod: 0x00
FCP rsp IU : 00000000 00000000 00000a02 000000ff
00000012 00000000
^^
and was wondering where that sense data would be or if the
corresponding PAY record "fcp_riu" was lost due to trace area wrapping.
So the fix here adds the following two lines to the same trace record:
FCP rsp IU len : 42
FCP rsp IU all : record not available anymore.
Similarly, the following LUN reset Task Management Function response
was missing the last two lines regarding the full FCP response IU
and its optional part with the FCP response info:
Timestamp : ...
Area : SCSI
...
Tag : lr_okay
...
FCP rsp inf cod: 0x00
FCP rsp IU : 00000000 00000000 00000100 00000000
00000000 00000008
^^
FCP rsp IU len : 32
FCP rsp IU all : record not available anymore.
As of today, depending on the kernel version we have
either fcp_sns or fcp_riu PAY trace records. See Linux kernel v4.14 commit
12c3e5754c80 ("scsi: zfcp: fix payload with full FCP_RSP IU in SCSI trace
records").
Always print non-zero payload length independent of payload type.
Actually this also fixes a regression for wrapped away fcp_sns.
If there is no fcp_sns it either wrapped away or it's a kernel with fcp_riu.
Only print fcp_riu if it contains more content than the preceding
unconditional fixed-size field "FCP rsp IU".

Function get_payload_records() reading from disk, blindly adds payload
record (junks) to a list in a 2-stage hierarchical hash keyed with
request ID and PAY area.
On adapter offline/online, zfcp resets the request ID to re-start with 1.
Hence it's not a unique foreign key in the lifetime of the PAY area.
The last payload record (junks) read for the same request ID and PAY area
is the one printed as named PAY field in the tool output.
This is not necessarily the chronologically last record due to PAY area
wrapping.
With this workaround, we:
* warn on reading PAY records if ambiguous entries occurred,
* print additional PAY timestamps which the user can compare
with the actual trace record timestamps to determine if they are close
enough to indicate a match.
We only found this by accident because we kept "short" "payload" being a
built-in part of some actual trace record types in areas HBA, SAN, SCSI.
For above cases, the full PAYload did not match the
built-in "short" "payload".
While at it, also add a comment that PAY output can also be wrong
in another case when junks of multi-part PAY records are missing due
to PAY area wrapping.
Below is an abbreviated example output with this workaround:

Most bootloaders use the BootLoaderSpec "title" field to name the entries
in their boot menu. The zipl bootloader used the "version" field instead,
since it was wrongly assumed that the zipl boot menu didn't support names
that contained spaces, which are usually present in a BLS "title" field.
But this is not the case, names with space characters are supported by the
IPL and is just a constraint of the section heading in the zipl.conf file.
So to be consistent with all the other bootloaders, use the "title" field
also on zipl when populating the boot menu entries from BLS files.

Currently the cpi.service systemd unit already works with
