Currently zpcictl silently accepts incorrect command line options while
it should be displaying an error message for invalid ones. There is a
check for the case when no arguments are supplied, but invalid arguments
or only specifying a device without an action does not display an error
nor give a failure exit code.
Fix this by changing parse_cmdline() to return a boolean indicating if
any arguments were supplied while exiting with an error and message when
invalid options are detected.

Re-enciphering an EP11 secure key may fail with an error message like:
"zkey-cryptsetup: Failed to re-encipher the secure volume key for device
'<device>'"
or
"zkey: Failed to re-encipher '<key>' from CURRENT to NEW master key"
or similar.
The verbose messages show the following debug message:
"Command XCP_ADM_REENCRYPT failed. rc = 0x20"
This is due to uninitialized variables, which might cause the EP11 admin
request to contain garbage data, causing it to fail with CKR_DATA_INVALID

zdev's initramfs hook does not add directives for enabling the root
device to the initrd if the root device is only configured in the
active configuration. As a result, a reboot using the new initrd fails
because the root device cannot be found.
This situation can occur for example when the zdev initramfs hook is
called from within an installer, where devices are only enabled in the
active configuration.
Address this situation by considering both the active and persistent
configuration of the root device during initramfs configuration. In case
the device is configured in both configurations, the persistent
configuration takes precedence.

The CCK will be able to be updated by an ultravisor call. For security
reasons, this feature must be enabled at Secure Execution header

Because this makes it possible to dump without having set a CCK
earlier, the requirement to specify a CCK when creating an image with
guest dump support is extended to also allow for CCK update instead.

In certain situations util_file_read_fd_buf() might return a larger
buffer than printable characters were read (e.g. a file was padded with
zeros). This can lead to util_file_read_fd() returning NULL with a freed
buffer even though a certain amount of printable characters were read.
This behaviour causes a regression introduced with commit 9efd1df31d
("ipl_tools: Refactor read helper using util_file_read_text_file()") in
ipl_tools were the scp_data sysfs attribute is padded with 0 to fit an 8
byte alignment required by the architecture.
Fix this by comparing the size read with the actual string length and
use the smaller value for further processing.
