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.

For details please see: http://httpd.apache.org/docs/2.4/upgrading.html#misc

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: 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.
