Eduard Shishkin 917d611883 zipl: add/move some definitions to header files
Make the listed changes which are needed to re-use some definitions
by the new zipl-debug(8) tool introduced by the next patch in the
series:

. Add definitions to boot_defs.h:
   . a named union disk_bloclkptr (instead of the anonymous one);
   . a named structure disk_program_table;
. Remove a 'typedef union disk_blockptr_t' from boot/stage2.h
  (cleanup), use the named union in boot_defs.h instead;
. Move the definition of scsi_layout types and the function
  get_scsi_layout() from install.c to install.h;
. Move definition of PROGRAM_TABLE_BLOCK_SIZE from bootmap.c to
  bootmap.h
