6d86f4bd11 analyze: add new "calendar" command
This little new command can parse, validate, normalize calendar events,
and calculate when they will elapse next. This should be useful for
anyone writing calendar events and who'd like to validate the expression
before running them as timer units.

ef5a8cb1a7 analyze: add get-log-level, get-log-target verbs
They’re counterparts to the existing set-log-level and set-log-target
verbs, simply printing the current value to stdout. This makes it
slightly easier to temporarily change the log level and/or target and
then restore the old value(s).

1eecafb8c1 man: use unicode ellipsis in more places
As requested in
https://github.com/systemd/systemd/pull/4864#pullrequestreview-12372557.

docbook will substitute triple dots for the ellipsis in man output, so this has
no effect on the troff output, only on HTML, making it infinitesimally nicer.

In some places we show output from programs, which use dots, and those places
should not be changed. In some tables, the alignment would change if dots were
changed to the ellipsis which is only one character. Since docbook replaces the
ellipsis automatically, we should leave those be. This patch changes all other
places.

d941ea22e3 analyze-verify: honour $SYSTEMD_UNIT_PATH, allow system paths to be ignored
SYSTEMD_UNIT_PATH=foobar: systemd-analyze verify barbar/unit.service
will load units from barbar/, foobar/, /etc/systemd/system/, etc.

SYSTEMD_UNIT_PATH= systemd-analyze verify barbar/unit.service
will load units only from barbar/, which is useful e.g. when testing
systemd's own units on a system with an older version of systemd installed.

f32b43bda4 core: remove support for RequiresOverridable= and RequisiteOverridable=
As discussed at systemd.conf 2015 and on also raised on the ML:

http://lists.freedesktop.org/archives/systemd-devel/2015-November/034880.html

This removes the two XyzOverridable= unit dependencies, that were
basically never used, and do not enhance user experience in any way.
Most folks looking for the functionality this provides probably opt for
the "ignore-dependencies" job mode, and that's probably a good idea.

Hence, let's simplify systemd's dependency engine and remove these two
dependency types (and their inverses).

The unit file parser and the dbus property parser will now redirect
the settings/properties to result in an equivalent non-overridable
dependency. In the case of the unit file parser we generate a warning,
to inform the user.

The dbus properties for this unit type stay available on the unit
objects, but they are now hidden from usual introspection and will
always return the empty list when queried.

This should provide enough compatibility for the few unit files that
actually ever made use of this.

12b42c7667 man: revert dynamic paths for split-usr setups
This did not really work out as we had hoped. Trying to do this upstream
introduced several problems that probably makes it better suited as a
downstream patch after all. At any rate, it is not releaseable in the
current state, so we at least need to revert this before the release.

 * by adjusting the path to binaries, but not do the same thing to the
   search path we end up with inconsistent man-pages. Adjusting the search
   path too would be quite messy, and it is not at all obvious that this is
   worth the effort, but at any rate it would have to be done before we
   could ship this.

 * this means that distributed man-pages does not make sense as they depend
   on config options, and for better or worse we are still distributing
   man pages, so that is something that definitely needs sorting out before
   we could ship with this patch.

 * we have long held that split-usr is only minimally supported in order
   to boot, and something we hope will eventually go away. So before we start
   adding even more magic/effort in order to make this work nicely, we should
   probably question if it makes sense at all.

681eb9cf2b man: generate configured paths in manpages
In particular, use /lib/systemd instead of /usr/lib/systemd in distributions
like Debian which still have not adopted a /usr merge setup.

Use XML entities from man/custom-entities.ent to replace configured paths while
doing XSLT processing of the original XML files. There was precedent of some
files (such as systemd.generator.xml) which were already using this approach.

This addresses most of the (manual) fixes from this patch:
http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/patches/Fix-paths-in-man-pages.patch?h=experimental-220

The idea of using generic XML entities was presented here:
http://lists.freedesktop.org/archives/systemd-devel/2015-May/032240.html

This patch solves almost all the issues, with the exception of:
- Path to /bin/mount and /bin/umount.
- Generic statements about preference of /lib over /etc.

These will be handled separately by follow up patches.

Tested:
- With default configure settings, ran "make install" to two separate
  directories and compared the output to confirm they matched exactly.
- Used a set of configure flags including $CONFFLAGS from Debian:
  http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/rules
  Installed the tree and confirmed the paths use /lib/systemd instead of
  /usr/lib/systemd and that no other unexpected differences exist.
- Confirmed that `make distcheck` still passes.

6ecb6cec66 analyze: change behaviour of combined --to/from--pattern
We would require a match against all three: patterns specified
with --to, with --from, and as positional arguments to show an
edge. This does not seem useful. Let instead the positional args
behave like they were specified in both --to and --from, which is
fairly intuitive and should be more useful.

  "unsigned int"
- alphabetic -> lexicographic (that way we automatically define how

a65615ca5d systemctl: move set-log-level to systemd-analyze
"systemctl set-log-level" is a command for analysis and tracing hence
"systemd-analyze" should be the better home for it, thus allowing us to

9ea9d4cf16 systemctl: move "dump" command from systemctl to systemd-analyze
It's an analysis command and its format is explicitly not covered by any
stability guarantees, hence move away from systemctl and into
systemd-analyze, minimizing the already large interface of systemctl a
bit.

This patch also adds auto-paging to the various systemd-analyze commands
where that makes sense

e55933db18 systemd-analyze: filter dot output
Make "systemd-analyze dot" output only lines with units matching
given glob(7) patterns. Add --from-pattern and --to-pattern options.
Without any patterns all relationships are printed as before.

A relationship must match the follwing expression:

    (isempty(from) || from[0] || from[1] || .. || from[n]) &&
    (isempty(to) || to[0] || to[1] || .. || to[n]) &&
    (isempty(P) || P[0] || P[1] || ... || P[n])

where from[] and to[] are lists of patterns provided with subsequent
--from-pattern and --to-pattern respectively. P[] is a list of  additional
patterns provided after the "dot" subcommand.
