e1f174ae22 zipl/libc.h: declare start as __noreturn function
Declare `start` as __noreturn function since the function doesn't
return. Use the gcc/clang built-in function `__builtin_unreachable` to
make clear that `lpsw` and `diag308(DIAG390_IPL, NULL)` doesn't
return (see https://gcc.gnu.org/onlinedocs/gcc/Other-Builtins.html and
https://clang.llvm.org/docs/LanguageExtensions.html#builtin-unreachable).

ac0ac48f6f zipl: Extend DASD stand-alone dumpers to drop zero pages
Update zipl DASD standalone dumpers for single-volume, multi-volume and FBA
to drop the sets of zero pages when dumping memory to disk. Thus, all
continuous sets of zero-megabytes in the memory are dropped during the dump
stage.
