Rename check_state() according the new meaning

Fix the check against multiple options in config file
Alexander Popov [Fri, 20 Jul 2018 15:55:43 +0000 (18:55 +0300)]
Use None as state of the options which are not found
That will change the check result
FAIL: "not found"
onto initial
FAIL: not found

Drop assertions which are now useless
anthraxx [Wed, 20 Jun 2018 21:27:40 +0000 (23:27 +0200)]
improve architecture in preparation for new features
This improves the opt storage using a kconfig key based dict to
avoid looping through all opts to get a certain entry by allowing
key based lookups.

Add rules for options disabled by grsecurity
Carefully extracted from their last public patch

Move some features to 'cut_attack_surface' category
STRICT_DEVMEM and IO_STRICT_DEVMEM, SECCOMP and SECCOMP_FILTER
are not self protection features. They cut attack surface.
I'm also not sure about SYN_COOKIES. Mark it with a comment.

Add kconfig-hardened-check.py
This script helps me to check the Linux kernel Kconfig option list
against my hardening preferences for x86_64.
Nobody likes checking configs manually. Let the computers do their job!
