Prep v221: Update and clean up build system to sync with upstream

This commit replays the moving around of source files that have been
done between systemd-219 and systemd-221.

Further the Makefile.am is synchronized with the upstream version and
then "re-cleaned".

A lot of functions, that are not used anywhere in elogind have been
coated into #if 0/#endif directives to further shorten the list of
dependencies.

All unneeded files have been removed.
