* Revert "cpu-freq: Try powersave if ondemand is not available"
This reverts commit 4dc56db37e.
Consult available scaling governors; for freshly generated configs, this provides a better experience than relying on a default that might not work everywhere.
Allow usage of list of strings instead of a comma-separated string
for filesystem options. Deprecate the comma-separated string style
with a warning message; convert this to a hard error after 16.09.
15.09 was just released, so this provides a deprecation period during
the 16.03 release.

I needed to add sdhci_acpi and mmc_block to my initrd modules in order to boot
my Chromebook. Looking under /sys/class/mmc_host/*/device/driver/module will
give us the sdhci_acpi dependency.
This makes the firmware available (or would, if someone switched off
enableAllFirmware). Corresponding kernel module should get auto-loaded.
See #9948. Close #9971.
Avoids this warning when running `nixos-rebuild switch`:

trace: Obsolete option `services.virtualboxGuest.enable' is used. It was renamed to `virtualisation.virtualbox.guest.enable'.
````
This option requests compatibility with older NixOS releases with
respect to stateful data, in cases where new releases have defaults
that might be incompatible with system state of existing NixOS
deployments. For instance, if we change the default version of
PostgreSQL, existing deployments will break if the new version can't
read databases created by the old version.
So for example, setting
system.stateVersion = "15.07";
requests that options like services.postgresql.package use defaults
corresponding to the 15.07 release branch. Note that
nixos-generate-config emits this option. (In the future, NixOps may
set system.stateVersion to the NixOS release in use when the machine
was created.)
See also #7939 for another motivating example.
Especially new users could be confused by this, so we're now marking
services.virtualbox.enable as obsolete and defaulting to
services.virtualboxGuest.enable instead. I believe this now makes it
clear, that this option is for guest additions only.

The NixOS manual says modules have the following signature:
{ config, lib, pkgs, ... }:
But our generated configuration.nix file lacks the 'lib' part. Add it.
The host id value gets generated by reading a 32-bit value from
/dev/urandom.
This makes programs that rely on a correct host id more reliable.
It also makes using ZFS more seamless, as you don't need to configure
the hostId manually; instead, it becomes part of your config from the
moment you install NixOS.
This reverts commit 469f22d717, reversing
changes made to 0078bc5d8f.

I tried to keep apparently-safe code in conflicts.
An escape char is needed to prevent "$ nix" from being evaluated and
expanded to an empty string. With this change the resulting text is
$ nix-env -qaP | grep wget
instead of
-env -qaP | grep wget
