0e4a4f56be journalctl: Make journalctl --user-unit= match on _SYSTEMD_USER_SLICE
journalctl --unit= already did this, and allows you to tail all the logs
for a certain slice easily. It seemed only natural to make --user-unit
behave in a similar way.

The _SYSTEMD_USER_SLICE field was not documented as being added by
journald, so I have added that to the documentation too.

Furthermore, I have documented the existing behaviour of --unit= and the
new behaviour of --user-unit=

The behaviour was actually not documented before, so I am also OK with
removing the match for the --unit= command instead.  The user would then
have to manually provide _SYSTEMD_SLICE= filter to journalctl in both
cases. Both options work for me.

7c30c3c44f journal: store the original timestamp as SYSLOG_TIMESTAMP=
This is useful if someone wants to recreate the original syslog datagram. We
already include timestamp information as _SOURCE_REALTIME_TIMESTAMP=, and in
normal use that timestamp, converted back to the form used by syslog
(Mth dd HH:MM:SS) would usually give the value. But there are various
circumstances where this might not be true. Most obviously, if the datagram is
sent a bit later after being prepared, the time is rounded to the nearest
second, and it might be off. This is especially bad around New Year when the
syslog timestamp wraps around. Then the same timezone and locale need to be
used to recreate the original timestamp. In the end doing this reliably is
complicated, and it seems much easier to just unconditionally include the
original timestamp.

If the original timestamp cannot be located, we store the full log line.
This way, it should be always possible to recreate the original input.

Example:
MESSAGE=x
SYSLOG_TIMESTAMP=Sep 15 15:07:58
SYSLOG_RAW
^]^@^@^@^@^@^@^@<13>Sep 15 15:07:58 HOST: x^@y
_PID=3318
_SOURCE_REALTIME_TIMESTAMP=1530743976393553

Fixes #2398.

df8701a3f2 journal: store the original syslog input as SYSLOG_RAW=
This allows the original stream to be recreated and/or verified. The new field
is written if any stripping was done or if the input message contained embeded
NULs.

$ printf '<13>Sep 15 15:07:58 HOST: x\0y' | nc -w1 -u -U /run/systemd/journal/dev-log

$ journalctl -o json-pretty ...
{
  ...
  "MESSAGE" : "x",
  "SYSLOG_RAW" : [ 60, 49, 51, 62, 83, 101, 112, 32, 49, 53, 32, 49, 53, 58, 48, 55, 58, 53, 56, 32, 72, 79, 83, 84, 58, 32, 120, 0, 121 ]
}

$ journalctl -o export ... | cat -v
...
MESSAGE=x
SYSLOG_RAW
^]^@^@^@^@^@^@^@<13>Sep 15 15:07:58 HOST: x^@y

This mostly fixes #4863.

fdbbee37d5 man: drop unused <authorgroup> tags from man sources
Docbook styles required those to be present, even though the templates that we
use did not show those names anywhere. But something changed semi-recently (I
would suspect docbook templates, but there was only a minor version bump in
recent years, and the changelog does not suggest anything related), and builds
now work without those entries. Let's drop this dead weight.

Tested with F26-F29, debian unstable.

0c69794138 tree-wide: remove Lennart's copyright lines
These lines are generally out-of-date, incomplete and unnecessary. With
SPDX and git repository much more accurate and fine grained information
about licensing and authorship is available, hence let's drop the
per-file copyright notice. Of course, removing copyright lines of others
is problematic, hence this commit only removes my own lines and leaves
all others untouched. It might be nicer if sooner or later those could
go away too, making git the only and accurate source of authorship
information.

818bf54632 tree-wide: drop 'This file is part of systemd' blurb
This part of the copyright blurb stems from the GPL use recommendations:

https://www.gnu.org/licenses/gpl-howto.en.html

The concept appears to originate in times where version control was per
file, instead of per tree, and was a way to glue the files together.
Ultimately, we nowadays don't live in that world anymore, and this
information is entirely useless anyway, as people are very welcome to
copy these files into any projects they like, and they shouldn't have to
change bits that are part of our copyright header for that.

hence, let's just get rid of this old cruft, and shorten our codebase a
bit.

11a1589223 tree-wide: drop license boilerplate
Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.

I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.

ec20fe5ffb journald: make maximum size of stream log lines configurable and bump it to 48K (#6838)
This adds a new setting LineMax= to journald.conf, and sets it by
default to 48K. When we convert stream-based stdout/stderr logging into
record-based log entries, read up to the specified amount of bytes
before forcing a line-break.

This also makes three related changes:

- When a NUL byte is read we'll not recognize this as alternative line
  break, instead of silently dropping everything after it. (see #4863)

- The reason for a line-break is now encoded in the log record, if it
  wasn't a plain newline. Specifically, we distuingish "nul",
  "line-max" and "eof", for line breaks due to NUL byte, due to the
  maximum line length as configured with LineMax= or due to end of
  stream. This data is stored in the new implicit _LINE_BREAK= field.
  It's not synthesized for plain \n line breaks.

- A randomized 128bit ID is assigned to each log stream.

With these three changes in place it's (mostly) possible to reconstruct
the original byte streams from log data, as (most) of the context of
the conversion from the byte stream to log records is saved now. (So,
the only bits we still drop are empty lines. Which might be something to
look into in a future change, and which is outside of the scope of this
work)

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.

5aded36978 man: add a mapping for external manpages
It is annoying when we have dead links on fd.o.

Add project='man-pages|die-net|archlinux' to <citerefentry>-ies.

In generated html, add external links to
http://man7.org/linux/man-pages/man, http://linux.die.net/man/,
https://www.archlinux.org/.

By default, pages in sections 2 and 4 go to man7, since Michael
Kerrisk is the autorative source on kernel related stuff.

The rest of links goes to linux.die.net, because they have the
manpages.

Except for the pacman stuff, since it seems to be only available from
archlinux.org.

Poor gummiboot gets no link, because gummitboot(8) ain't to be found
on the net. According to common wisdom, that would mean that it does
not exist. But I have seen Kay using it, so I know it does, and
deserves to be found. Can somebody be nice and put it up somewhere?

82adf6af7c nspawn,man: use a common vocabulary when referring to selinux security contexts
Let's always call the security labels the same way:

  SELINUX: "SELinux Security Context"

And the low-level encapsulation is called "seclabel". Now let's hope we
stick to this vocabulary in future, too, and don't mix "label"s and
"security contexts" and so on wildly.
