Debian carried a patch forever that allowed zipl to run even if not all
menu items had files attached. If a required file is missing for an
entry (e.g. vmlinuz.old or initrd.img.old) and it is marked as
"optional" in the config, the section will be skipped. This allows
zipl to install after bootstrapping, as booting on s390 still relies
on the kernel/initrd symlinks in the root directory.

Each ipl type takes at least a kernel image, parameter line and initrd
parameter. This is duplicated all over the place in the current
implementation. To simplify this, add struct job_common_ipl_data which
will hold this data.

When installing a boot record for "ipl" and "menu" job, always add
an environment block as a boot component located in bootmap file
at offset alinged on file system block size boundary. When adding,
first try to import environment from a file at location specified
by newly introduced "--environment" zipl option, or by default at
"/etc/ziplenv". If nothing was imported, then add a blank environment
block. Optionally print the content of the environment block.
Store environment block size and address (as of boot component) in
stage3_parms.
Change interface of add_ipl_program(): add 2 additional arguments:
a pointer to bootmap file name and a predicate indicating if we
need to add environment block as a boot component.

The hierarchy of the secure boot settings in the config file should be:
defaultboot > menu > section
This patch implements this hierarchy and adds a check if a valid option is
specified and prints an error message otherwise.

Add a command line option and configuration section keyword to control
the zIPL secure boot support. This option is named "secure" and can take
one of three values:
auto (default)
Write signatures if available and supported by the system.
1
Signatures are written independent of support indicated by the local
system. Also missing signatures for stage 3 and kernel IPL files
will result in an error.
0
No signatures will be written.
