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>

-Porting systemd To New Distributions
-
-HOWTO:
-        You need to make the follow changes to adapt systemd to your
-        distribution:
-
-        0) Make your distribution recognized via the autoconf checks
-        in configure.ac. Grep for the word "fedora" (case
-        insensitively) and you should be able to find the places where
-        you need to add/change things.
-
-        1) Patch src/hostname-setup.c so that systemd knows where to
-        read your host name from. You might also want to update
-        status_welcome() in util.c.
-
-        2) Check the unit files in units/ if they match your
-        distribution. Most likely you will have to make additions to
-        units/*.m4 and create a copy of units/fedora/ with changes for
-        your distribution.
-
-        3) Adjust Makefile.am to register the unit files you added in
-        step 2. Also you might need to update the m4 invocation in
-        Makefile.am. Grep for the word "fedora" (case insensitively)
-        and you should be able to find the places where you need to
-        add/change things.
-
-        4) Try it out. Play around with 'systemd --test --system' for
-        a test run of systemd without booting. This will read the unit
-        files and print the initial transaction it would execute
-        during boot-up. This will also inform you about ordering loops
-        and suchlike.

-CONTRIBUTING UPSTREAM:
-        We are interested in merging your changes upstream, if they
-        are for a big, and well-known distribution. Unfortunately we
-        don't have the time and resources to maintain
-        distribution-specific patches for all distributions on the
-        planet, hence please do not send us patches that add systemd
-        support for non-mainstream or niche distributions.
-
-        Thank you for understanding.
-
-BE CONSIDERATE:
-        We'd like to keep differences between the distributions
-        minimal. This both simplifies our maintenance work, as well
-        as it helps administrators to move from one distribution to
-        another.
-
-        Hence we'd like to ask you to keep your changes minimal, and
-        not rename any units without a very good reason (if you need a
-        particular name for compatibility reasons, consider using
-        alias names via symlinks). Before you make changes that change
-        semantics from upstream, please talk to us!
-
-        In SysV almost every distribution uses a different
-        nomenclature and different locations for the boot-up
-        scripts. We'd like to avoid chaos like that with systemd right
-        from the beginning. So please, be considerate!
