additional options for the [Service] section.

99479986ea man: Align ExecStop= documentation with actual kill behavior (#4974)
The manpage claimed that ExecStop would be followed immediately by
SIGKILL, whereas the actual behavior is to go through KillMode= and
KillSignal= first.

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.

330785f5ca basic/extract-word,man: clarify "correction" of invalid escapes
Our warning message was misleading, because we wouldn't "correct" anything,
we'd just ignore unkown escapes. Update the message.

Also, print just the extracted word (which contains the offending sequences) in
the message, instead of the whole line.

Fixes #4697.

136dc4c435 core: set $SERVICE_RESULT, $EXIT_CODE and $EXIT_STATUS in ExecStop=/ExecStopPost= commands
This should simplify monitoring tools for services, by passing the most basic

thus making it unnecessary to retrieve them explicitly via the bus.

43eb109aa9 core: change ExecStart=! syntax to ExecStart=+ (#3797)
As suggested by @mbiebl we already use the "!" special char in unit file
assignments for negation, hence we should not use it in a different context for
privileged execution. Let's use "+" instead.

cf677fe686 core/execute: add the magic character '!' to allow privileged execution (#3493)
This patch implements the new magic character '!'. By putting '!' in front
of a command, systemd executes it with full privileges ignoring paramters
such as User, Group, SupplementaryGroups, CapabilityBoundingSet,
AmbientCapabilities, SecureBits, SystemCallFilter, SELinuxContext,
AppArmorProfile, SmackProcessLabel, and RestrictAddressFamilies.

Fixes partially https://github.com/systemd/systemd/issues/3414
Related to https://github.com/coreos/rkt/issues/2482

Testing:
1. Create a user 'bob'
2. Create the unit file /etc/systemd/system/exec-perm.service
   (You can use the example below)
3. sudo systemctl start ext-perm.service
4. Verify that the commands starting with '!' were not executed as bob,
   4.1 Looking to the output of ls -l /tmp/exec-perm
   4.2 Each file contains the result of the id command.

6bf0f408e4 core: make the StartLimitXYZ= settings generic and apply to any kind of unit, not just services
This moves the StartLimitBurst=, StartLimitInterval=, StartLimitAction=, RebootArgument= from the [Service] section
into the [Unit] section of unit files, and thus support it in all unit types, not just in services.

This way we can enforce the start limit much earlier, in particular before testing the unit conditions, so that
repeated start-up failure due to failed conditions is also considered for the start limit logic.

For compatibility the four options may also be configured in the [Service] section still, but we only document them in
their new section [Unit].

This also renamed the socket unit failure code "service-failed-permanent" into "service-start-limit-hit" to express
more clearly what it is about, after all it's only triggered through the start limit being hit.

Finally, the code in busname_trigger_notify() and socket_trigger_notify() is altered to become more alike.

ce359e98f8 core: when a service's ExecStartPre= times out, skip ExecStop=
This makes sure we never run two control processes at the same time, we cannot keep track off.

This introduces a slight change of behaviour but cleans up the definition of ExecStop= and ExecStopPost=. The former is
now invoked only if the service managed to start-up correctly. The latter is called even if start-up failed half-way.
Thus, ExecStopPost= may be used as clean-up step for both successful and failed start-up attempts, but ExecStop='s
purpose is clearly defined as being responsible for shutting down the service and nothing else.

The precise behaviour of this was not documented yet. This commit adds the necessary docs.

c129bd5df3 man: document automatic dependencies
For all units ensure there's an "Automatic Dependencies" section in the
man page, and explain which dependencies are automatically added in all
cases, and which ones are added on top if DefaultDependencies=yes is
set.

This is also done for systemd.exec(5), systemd.resource-control(5) and
systemd.unit(5) as these pages describe common behaviour of various unit
types.

12e2683d48 man: Describe when ExecStartFoo= commands are run in more detail
Previously it was just descibed that ExecStartPost= commands were
started "after" the ExecStart= command(s).
This hasn't specified after which event, which varies from after it has
been started, after it has exited, after it has sent READY=1 or after it
has taken the bus name, depending on Type=.

This now describes that it happens after the *service* has "started",
as defined by the Type=, and provides some clarification about precisely
when this is.

This may be unnecessary duplication, but it removes the ambiguity as to
whether RemainAfterExit=no means that ExecStartPost= shouldn't be
started because it means the service has stopped when the ExecStart=
command terminates, not "started".

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.
