20089f95e8 man: provide "permalinks" to sections and terms
So no one needs to say "go to fd.o/software/systemd/man, open page X,
then scroll down to section 3, and look for ..." anymore.

8621b1109b journal: Set the default keep free value to 15% (up from 5%)
As some SSDs are still seeing performance degredation when
reaching 85% usage the default value of 5% seems a little low.

Set this to 15% by default.

845c53246f man: add various filenames to the index
Everything which is an absolute filename marked with <filename></filename>
lands in the index, unless noindex= attribute is present. Should make
it easier for people to find stuff when they are looking at a file on
disk.

Various formatting errors in manpages are fixed, kernel-install(1) is
restored to formatting sanity.

8368868452 Add help option to bootchart man page
Bootchart has a help option. For the sake of consistency, this patch
adds it to the man page.

Also, the TODO is updated. Bootcharts were added to the journal in
commit c4d58b0.

00d1818bb7 man: we need to be more careful with the unit search paths we document
We generally document the suggested paths, not the paths possible in
weird, non-standard setups. We do this in order to not confuse
administrators/users unnecessarily and to push people to install things
into the same directories on all distributions.

We are PID 1 after all, the really basic building block of the OS.
Unlike for an app there's very little benefit in being entirely
relocatable.

432c30d25f man/systemd.xml: change the signal names to kill systemd
Using the signal name to put systemd in debug mode with bash results in:
 $ kill -s SIGRTMIN+22 1
 bash: kill: SIGRTMIN+22: invalid signal specification

whereas this works:
 $ kill -s SIGRTMAX-8 1

/usr/bin/kill understands both signal names, so just change them to the
bash names.

7027ff61a3 nspawn: introduce the new /machine/ tree in the cgroup tree and move containers there
Containers will now carry a label (normally derived from the root
directory name, but configurable by the user), and the container's root
cgroup is /machine/<label>. This label is called "machine name", and can
cover both containers and VMs (as soon as libvirt also makes use of
/machine/).

libsystemd-login can be used to query the machine name from a process.

This patch also includes numerous clean-ups for the cgroup code.

20b3f379cf systemctl: allow multiple arguments to --type
This mirrors --property, and is generally useful.

New functionality is used in bash completion.

In case of zsh completion, new functionality is less useful
because of caching. Nevertheless, zsh completion for restart
is made to behave more-or-less the same as bash completion.
At least sockets can be restarted.

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.

1a13e31d27 build-sys,man: use XML entities to substite strings
This makes it easier to add substitutions to man pages,
avoiding the separate transformation step.

mkdir -p's are removed from the rule, because xsltproc will
will create directories on it's own.

All in all, two or three forks per man page are avoided,
which should make things marginally faster.

Unfortunately python parsers must too be tweaked to handle
entities. This isn't particularly easy: with lxml a custom
Resolver can be used, but the stdlib etree doesn't support
external entities *at all*. So when running without lxml,
the entities are just removed. Right now it doesn't matter,
since the entities are not indexed anyway. But I intend to
add indexing of filenames in the near future, and then the
index generated without lxml might be missing a few lines.
Oh well.
