linux: translate config to structured config Instead of using a string to describe kernel config, use a nix attribute set, then converted to a string. - allows to override the config, aka convert 'yes' into 'modules' or vice-versa - while for now merging different configs is still crude (last spec wins), at least there should be only one CONFIG_XYZ value compared to the current string config where the first defined would be used and others ignored.

# WARNING/NOTE: whenever you want to add an option here you need to either
# * mark it as an optional one with `option`,
# * or make sure it works for all the versions in nixpkgs,
# * or check for which kernel versions it will work (using kernel
# changelog, google or whatever) and mark it with `whenOlder` or
# `whenAtLeast`.
# Then do test your change by building all the kernels (or at least
# their configs) in Nixpkgs or else you will guarantee lots and lots
# of pain to users trying to switch to an older kernel because of some
# hardware problems with a new one.

Unify the Linux kernel configurations Having N different copies of the NixOS kernel configuration is bad because these copies tend to diverge. For instance, our 3.10 config lacked some modules that were enabled in older configs, probably because the 3.10 config had been copied off an earlier version of some older kernel config. So now there is a single kernel config in common-config.nix. It has a few conditionals to deal with new/removed kernel options, but otherwise it's pretty straightforward. Also, a lot of cut&paste boilerplate between the kernel Nix expressions is gone (such as preConfigure).
