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>

-Bugfixes:
-* check systemd-tmpfiles for selinux context hookup for mknod(), symlink() and similar
-
-* swap units that are activated by one name but shown in the kernel under another are semi-broken
-
-* make anaconda write timeout=0 for encrypted devices
-
-* Dangling symlinks of .automount unit files in .wants/ directories, set up
-  automount points even when the original .automount file did not exist
-  anymore. Only the .mount unit was still around.
-
-* make polkit checks async
-
-* properly handle .mount unit state tracking when two mount points are stacked one on top of another on the exact same mount point.
-
-F18:
-
-* Retest multi-seat
-
-* add rpm macros for %rulesdir, %hwdbdir, update rules/hwdb call
-
-Features:
-
-* add API to close/reopen/get fd for journal client fd in libsystemd-journal.
-
-* maybe add API to send pairs of iovecs via sd_journal_send
-
-* fallback to /dev/log based logging in libsystemd-journal, if we can't log natively?
-
-* declare the local journal protocol stable in the wiki interface chart
-
-* introduce ntp.service (or suchlike) as symlink that is used to arbitrate between various
-  NTP implementations
-
-* sd-journal: don't return fields > a threshold by default
-* journal: reuse XZ context
-* sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
-
-* introduce ntp.service (or suchlike) as symlink that is used to arbitrate between various NTP implementations
-
-* timer units should get the ability to trigger when:
-    - CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
-    - DST changes
-
-* update the kernel's TZ (sys_tz) when DST changes
-
-* sync down the system time to the RTC when:
-    - CLOCK_REALTIME makes jumps (the user explicitely requested a time set)
-    - DST/timezone changes && ntp is active && RTC-in-localtime (never do it without ntp)
-  This takes care of syncing ntpdate updates to the RTC, and DST updates for localtime
-  mode, it will never touch the RTC if the no reliable time source is active or the
-  user did not request anything like it.
-
-* When we begin with system shutdown all kind of suspend/hibernation should be prohibited until shutdown/reboot
-
-* When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
-
-* hwdb:
-  - implement conditional properties (dmi matches)
-  - hwdb --filter=ID_DRIVE_*
-  - find out what to do for blockdevs and skipping scsi modaliases
-  - move writing code to src/libudev/libudev-hwdb-private.c
-
-* if booted in "quiet" mode, and an error happens, turn on status output again, so that the emergency mode isn't totally surprising
-
-* localectl: add listing support for X11 keymaps, by parsing /usr/share/X11/xkb/rules/xorg.lst
-
-* libunwind support for coredump pattern hook, and includes this in
-  the message for coredumps. After all, libunwind is now capable to
-  unwind coredumps since a few weeks ago. This probably requires that
-  we have nice support for multi-line messages on display in logs-show.c.
-
-* figure out relation of --all and --full in the various tools
-
-* journal: when writing journal auto-rotate if time jumps backwards
-
-* introduce new "journal" group in place of adm? introduce groups for the various mini daemons?
-
-* journal: add a setgid "adm" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
-
-* link up selected blog stories from man pages?
-
-* journactl: support negative filtering, i.e. FOOBAR!="waldo",
-  and !FOOBAR for events without FOOBAR.
-
-* print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
-
-* add libsystemd-password or so to query passwords during boot using the password agent logic
-
-* journal: when rotating, copy over old acls/access mode
-
-* journal: document why we do not give ownership to journal files to the user that created them but use FS ACLs for that
-
-* journal: send out marker messages every now and then, and immediately sync with fdatasync() afterwards, in order to have hourly guaranteed syncs.
-
-* journal: when we haven't written anything in a while, sync to disk and mark file as offline, in order to be more often than not in a clean state
-
-* journal-send.c, log.c: when the log socket is clogged, and we drop, count this and write a message about this when it gets unclogged again.
-
-* If we show an error about a unit (such as not showing up) and it has no Description string, then show a description string generated form the reverse of unit_name_mangle().
-
-* fedup: add --unit to systemctl switch-root somehow
-* fedup: don't delete initrd on switch-root
-* fedup: generator
-
-* journal: find a way to allow dropping history early, based on priority, other rules
-
-* journal: When used on NFS, check payload hashes
-
-* journal: When used on NFS make sure wake up sd_journal_wait() every 2s, to handle missing inotify
-
-* document that people can use file system ACLs to manage access to journal files, with example
-
-* don't show cgroup in "systemctl status" if empty/non-existent, especially for foreign .mount units
-
-* timedated: export boolean that clarifies whether NTP is even available
-
-* timedated: refuse time changes when NTP is on
-
-* clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
-
-* document unit_name_mangle()
-
-* add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
-
-* introduce generic AUGMENT_PID=, AUGMENT_DEVICE= fields
-
-* deal with sendmail/postfix exclusivity
-
-* systemctl enable: improve the success messages (i.e. more human readable, less shell-like)
-
-* systemctl enable: fail if target to alias into doesn't exist? maybe show how many units are enabled afterwards?
-
-* on shutdown: move utmp, wall, audit logic all into PID 1 itself, get rid of systemd-update-utmp-runlevel
-
-* add "provisioning" instructions to setup an empty /etc + /var
-    - used to setup a new container from a shared /usr
-    - superset of tmpfiles model
-    - instructions shipped by packages and stored in /usr/lib/
-    - compose /etc/passwd and /etc/group, copy files
-    - able to create uid + gid used by packages, for file ownership
-
-* make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
-  waiting for the timeout
-
-* high level net_prio setting in execution context
-
-* Introduce journalctl -b <nr> to show journal messages of a previous boot
-
-* hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
-
-* currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab isn't
-
-* WorkingDirectory: support env var replacements like in ExecStart= so that people can use $HOME
-
-* refuse boot if /etc/machine-id is not useful
-
-* nspawn: consider changing users for -u with su, so that NSS resolving works correctly
-
-* nspawn: implement personality changes a la linux32(8)
-
-* nspawn: reset all aux groups
-
-* cryptsetup-generator: warn if the password files are world-readable
-
-* cryptsetup-generator: add RequiresMountsFor= to cryptseup service files referencing a file, similar for devices
-
-* cryptsetup-generator: allow specification of passwords in crypttab itself
-

-  [Install] units of other units, unless those units are disabled
-
-* need to update LGPL2.1 text to newest version (with updated FSF address)

-
-* move debug shell to tty6 and make sure this doesn't break the gettys on tty6

-
-* explore multiple service instances per listening socket idea
-
-* testing tool for socket activation: some binary that listens on a socket and passes it on using the usual socket activation protocol to some server.
-
-* shutdown: don't read-only mount anything when running in container
-
-* nspawn: --read-only is not applied recursively to submounts
-
-* MountFlags=shared acts as MountFlags=slave right now.
-
-* ReadOnlyDirectories= is not applied recursively to submounts
-
-* drop PID 1 reloading, only do reexecing (difficult: Reload()
-  currently is properly synchronous, Reexec() is weird, because we
-  can't delay the response properly until we are back, so instead of
-  being properly synchronous we just keep open the fd and close it
-  when done. That means clients don't get a successful method reply,
-  but much rather a disconnect on success.
-
-* document that service reload may be implemented as service reexec
-
-* remember which condition failed for services, not just the fact that something failed
-
-* use opterr = 0 for all getopt tools
-
-* properly handle loop back mounts via fstab, especially regards to fsck/passno

-* syscall filter: add knowledge about compat syscalls
-
-* syscall filter: don't enforce no new privs?
-
-* syscall filter: option to return EPERM rather than SIGSYS?
-
-* syscall filter: port to libseccomp
-
-* logind: wakelock/opportunistic suspend support
-
-* systemd-analyze post-boot is broken for initrd
-
-* man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
-
-* .device aliases need to be implemented with the "following" logic, probably.
-
-* refuse taking lower-case variable names in sd_journal_send() and friends.
-
-* load-fragment: when loading a unit file via a chain of symlinks
-  verify that it isn't masked via any of the names traversed.

-  Acpi(PNP0A03,0)/Pci(1F|2)/?/HD(Part1,Sig1FCBC57F-4BFC-4C2B-91A3-9C84FBCD9AF1)
-  '/' is the separator for the device path list
-  HD(Part1,Sig1FCBC57F-4BFC-4C2B-91A3-9C84FBCD9AF1) contains the GPT UUID of the ESP
-
-* read the bootloader performance data (raw TSC) in systemd-analyze

-
-* improve !/proc/*/loginuid situation: make /proc/*/loginuid less dependent on CONFIG_AUDIT,
-  or use the users cgroup information when /proc/*/loginuid is not available.
-
-* pam_systemd: try to get old session id from cgroup, if audit sessionid cannot be determined
-
-* pam: when leaving a session explicitly exclude the ReleaseSession() caller process from the killing spree

-
-* verify that the AF_UNIX sockets of a service in the fs still exist
-  when we start a service in order to avoid confusion when a user

-
-External:
-
-* dbus:
-   - dbus --user
-   - natively watch for dbus-*.service symlinks (PENDING)
-   - allow specification of socket mode/umask when allocating DBusServer
-   - allow disabling of fd passing when connecting a AF_UNIX connection
-   - allow disabling of UID passing for AUTH EXTERNAL
-   - always pass cred data along each message
-
-* fix alsa mixer restore to not print error when no config is stored
-
-* gnome-shell python script/glxinfo/is-accelerated must die
-
-* make cryptsetup lower --iter-time
-
-* patch kernel for xattr support in /dev, /proc/, /sys and /sys/fs/cgroup?
-
-* NTP: the kernel's 11-minutes-mode syncs the system time to the RTC, but only
-  in an ~30 minutes window. It does not adjust larger differences. Find a way
-  to tell the kernel, to always do a full time sync when the RTC is in UTC and
-  we are in 11-minutes-mode. When we trust the system time to NTP we also want
-  the RTC to sync up.
-
-* kernel: add device_type = "fb", "fbcon" to class "graphics"
-
-Regularly:
-
-* look for close() vs. close_nointr() vs. close_nointr_nofail()
-
-* check for strerror(r) instead of strerror(-r)
-
-* Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
-
-* %m in printf() instead of strerror(errno);
-
-* pahole
-
-* set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!
-
-* use secure_getenv() instead of getenv() where appropriate
-
-Scheduled for removal or fixing:
-
-* xxxOverridable dependencies (probably: fix)
-
-* support for early-boot SysV services (definitely: remove)
-
-* insserv support (definitely: remove)
