Subject: [PATCH 0/3] Kconfig: Refactor memory initialization hardening

This is a proposed alternative for the memory initialization series,
which refactoring the existing gcc plugins into a separate Kconfig
file and collects all the related options together with some more
language to describe their differences. The last patch adds the
Clang auto init option, as done by Alexander Potapenko.

Since there isn't really a good way to "select" with dependencies,
I've left out CONFIG_INIT_ALL_MEMORY for the moment...

  Kconfig: Create "kernel hardening" config area
  kbuild: Move stackleak config to Kconfig.hardening
  kbuild: Implement Clang's stack initialization
