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.
