Revert " nat: enable NAT for multiple networks"

This reverts commit a24e4b4af20a0b95c13edfbf4b5705a27ff8f045.
making ati proprietary drivers work again

However SLIM is still broken and you have to create a
/usr/lib/dri/fglrx_dri.so symlink pointing to
/run/opengl-driver/lib/fglrx_dri.so

At least fgl_glxgears shows 10 times more frames per second now
 - fix indention, clarify parameter descriptions, and use 'exec' instead of 'script' in the hostapd job
Change the default value of programs.ssh.forwardX11 to false.

Forwarding X11 to untrusted servers is extremely insecure; see for example

firewall: option to enable the rpfilter netfilter module

This is meant to replace /proc/sys/net/ipv4/conf/*/rp_filter, which
only works for ipv4. Furthermore, it's nicer to handle this kind of
filtering in the firewall.

There are some more subtle differences, please see:
https://home.regit.org/netfilter-en/secure-use-of-helpers/

I chose to enable this by default (when the firewall is enabled) as
it's a good idea in general. Only people with advanced routing needs
might not want this, but I guess they don't use the nixos firewall
anyway and use a custom solution. Furthermore, the option only becomes
available in kernel 3.3+, so conservative nixos users that just stick
to the default kernel will not need to act now just yet.
firewall: options to select connection-tracking helpers

My main reason for adding this is the ability to turn off helpers
altogether. If you are not using any of the special protocols, keeping
them turned off is safest, and in case you do want to use them, it's
best to configure them through the new CT target for your network
topology. Perhaps some sane defaults for nixos can be examined in the
future.

This change has no impact if you don't touch the added options, so no
need to adapt.

modules/programs/bash: improve bash completion support

The new configuration.nix option 'environment.enableBashCompletion'
determines whether bash completion is automatically enabled system-wide
for all interactive shells or not. The default setting is 'off'.

apache-httpd: Use authn_core for version >= 2.3.

Beginning with version 2.3, the authn were refactored. As a result, authn_alias
is now part of the new module authn_core, so let's use authn_core instead of
authn_alias.

apache-httpd: Dynamically load MPM module in v2.4.

Now, MPMs can be loaded at runtime and it's no longer required to compile in one
of the MPM modules statically. So, if version is >= 2.4, load the MPM module
corresponding to the multiProcessingModule value of the service module.

For details, please see: http://httpd.apache.org/docs/2.4/mpm.html

apache-httpd: Add unixd for 2.4, needed by "User".

Beginning with 2.4 mod_unixd is needed to supply Unix usernames and groups for
the web server. For details please have a look at:

apache-httpd: Properly wrap access directives.

The Order/Deny directives are deprecated in version 2.4, so we're going to
define two wrappers for allDenied and allGranted in order to properly generate
configurations for both version 2.2 and 2.4.

For more information an access control changes, see:

apache-httpd: Avoid NameVirtualHost in >= v2.4.

NameVirtualHost no longer has any effect on version 2.4 and just emits ugly
warnings, so let's not use it if we use 2.4.

apache-httpd: Create runtime dir for version 2.4.

By default the path is determined related to ServerRoot. Unfortunately
ServerRoot is pointing to the Nix store and the web server can't write to it.

We now create a directory called "runtime" withen the stateDir and point
DefaultRuntimeDir to it.

For more information on the DefaultRuntimeDir directive, please see:

apache-httpd: Simplify all versionOlder calls.

We now just have a simple attribute called "version24" which replaces all those
pesky versionOlder that were spreading throughout the file and makes things way
more readable.
