Eduard Shishkin 2945593991 zipl/src: Support (create/boot-with) different program tables per target ...

Replace struct install_set with a new type containing multiple
program tables and program components. Refactor the code accordingly.

When retrieving device INFO, for each mirror complete a respective
structure disk_info in the INFO.BASE array.

When building a bootmap, for each mirror create a separate program
table (or a pair of tables in case of DASD - for CCW-TYPE IPL and
for LD-IPL), using respective components in the arrays INFO.BASE and
BIS.MIRRORS

Make data of program components added via get_component_buffer() and
get_component_file() be duplicated per each mirror.

Make boot record on each mirror point out to a respective program
table in the bootmap (when booting from different mirrors, different
program tables in the bootmap are used).

This patch doesn't make functional changes. However, test cases
comparing boot meta-data dumps of different mirrors may fail (since
boot records on different mirrors now refer different copies of boot
data). This will be fixed by the next patches in the series which
allow boot data to be reused.
