172dc1336f nixos: add grsecurity module (#1875)
This module implements a significant refactoring in grsecurity
configuration for NixOS, making it far more usable by default and much
easier to configure.

 - New security.grsecurity NixOS attributes.
   - All grsec kernels supported
   - Allows default 'auto' grsec configuration, or custom config
   - Supports custom kernel options through kernelExtraConfig
   - Defaults to high-security - user must choose kernel, server/desktop
     mode, and any virtualisation software. That's all.
   - kptr_restrict is fixed under grsecurity (it's unwriteable)
 - grsecurity patch creation is now significantly abstracted
   - only need revision, version, and SHA1
   - kernel version requirements are asserted for sanity
   - built kernels can have the uname specify the exact grsec version
     for development or bug reports. Off by default (requires
     `security.grsecurity.config.verboseVersion = true;`)
 - grsecurity sysctl support
   - By default, disabled.
   - For people who enable it, NixOS deploys a 'grsec-lock' systemd
     service which runs at startup. You are expected to configure sysctl
     through NixOS like you regularly would, which will occur before the
     service is started. As a result, changing sysctl settings requires
     a reboot.
 - New default group: 'grsecurity'
   - Root is a member by default
   - GRKERNSEC_PROC_GID is implicitly set to the 'grsecurity' GID,
     making it possible to easily add users to this group for /proc
     access
 - AppArmor is now automatically enabled where it wasn't before, despite
   implying features.apparmor = true

The most trivial example of enabling grsecurity in your kernel is by
specifying:

    security.grsecurity.enable          = true;
    security.grsecurity.testing         = true;      # testing 3.13 kernel
    security.grsecurity.config.system   = "desktop"; # or "server"

This specifies absolutely no virtualisation support. In general, you
probably at least want KVM host support, which is a little more work.
So:

    security.grsecurity.enable = true;
    security.grsecurity.stable = true; # enable stable 3.2 kernel
    security.grsecurity.config = {
      system   = "server";
      priority = "security";
      virtualisationConfig   = "host";
      virtualisationSoftware = "kvm";
      hardwareVirtualisation = true;
    }

This module has primarily been tested on Hetzner EX40 & VQ7 servers
using NixOps.

for managing the iptables rules.)

e206684110 Use PostgreSQL 9.3's pg_isready to wait for connectivity
The postgresql module has a postStart section that waits for a database
to accept connections before continuing. However, this assumes various
properties about the database - specifically the database user
and (implicitly) the database name. This means that for old
installations, this command fails because there is no 'postgres' user,
and the service never starts.

While 7deff39 does create the 'postgres' user, a better solution is to
use `pg_isready`, who's sole purpose is to check if the database is
accepting connections. This has no dependency on users, so should be
more robust.

7de29bd26f Create the 'postgres' superuser
Old PostgreSQL installations were created using the 'root' database
user. In this case, we need to create a new 'postgres' account, as we
now assume that this is the superuser account.

Unfortunately, these machines will be left with a 'root' user as
well (which will have ownership of some databases). While PostgreSQL
does let you rename superuser accounts, you can only do that when you
are connected as a *different* database user. Thus we'd have to create a
special superuser account to do the renaming. As we default to using
ident authentication, we would have to create a system level user to do
this. This all feels rather complex, so I'm currently opting to keep the
'root' user on these old machines.
