Isolation of udev code from remaining systemd
This commit is a first attempt to isolate the udev code from the remaining code base. It intentionally does not modify any files but purely delete files which, on a first examination, appear to not be needed. This is a sweeping commit which may easily have missed needed code. Files can be retrieved by doing a checkout from the previous commit: git checkout 2944f347d0 -- <filename>

- <title>Description</title>
-
- <para><command>systemd-ask-password</command> may be
- used to query a system password or passphrase from the
- user, using a question message specified on the
- command line. When run from a TTY it will query a
- password on the TTY and print it to STDOUT. When run
- with no TTY or with <option>--no-tty</option> it will
- query the password system-wide and allow active users
- to respond via several agents. The latter is
- only available to privileged processes.</para>
-
- <para>The purpose of this tool is to query system-wide
- passwords -- that is passwords not attached to a
- specific user account. Examples include: unlocking
- encrypted hard disks when they are plugged in or at
- boot, entering an SSL certificate passphrase for web
- and VPN servers.</para>
-
- <para>Existing agents are: a boot-time password agent
- asking the user for passwords using Plymouth; a
- boot-time password agent querying the user directly on
- the console; an agent requesting password input via a
- <citerefentry><refentrytitle>wall</refentrytitle><manvolnum>1</manvolnum></citerefentry>
- message; an agent suitable for running in a GNOME
- session; a command line agent which can be started
- temporarily to process queued password requests; a TTY
- agent that is temporarily spawned during
- <citerefentry><refentrytitle>systemctl</refentrytitle><manvolnum>1</manvolnum></citerefentry>
- invocations.</para>
-
- <para>Additional password agents may be implemented
- according to the <ulink
- url="http://www.freedesktop.org/wiki/Software/systemd/PasswordAgents">systemd
- Password Agent Specification</ulink>.</para>
-
- <para>If a password is queried on a TTY the user may
- press TAB to hide the asterisks normally shown for
- each character typed. Pressing Backspace as first key
- achieves the same effect.</para>
