. Support multiple namespaces in the installed environment block;
. Add option --site (-S) to specify a particular namespace
when operating on the installed environment block;
. Add option --effective-site (-E) to specify a particular

(--list), it displays zIPL environment that would take place if
the specified namespace was activated at boot time;

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.
