Remove systemd-bootchart 

This commit rips out systemd-bootchart. It will be given a new home, outside
of the systemd repository. The code itself isn't actually specific to
systemd and can be used without systemd even, so let's put it somewhere
else.

<title>Description</title>
<para>
<command>systemd-bootchart</command> is a tool, usually run at
system startup, that collects the CPU load, disk load, memory
usage, as well as per-process information from a running system.
Collected results are output as an SVG graph. Normally,
systemd-bootchart is invoked by the kernel by passing
<option>init=<filename>/usr/lib/systemd/systemd-bootchart</filename></option>
on the kernel command line. systemd-bootchart will then fork the
real init off to resume normal system startup, while monitoring
and logging startup information in the background.
</para>
<para>
After collecting a certain amount of data (usually 15–30
seconds, default 20 s) the logging stops and a graph is
generated from the logged information. This graph contains vital
clues as to which resources are being used, in which order, and
where possible problems exist in the startup sequence of the
system. It is essentially a more detailed version of the
<command>systemd-analyze plot</command> function.
</para>
<para>
Of course, bootchart can also be used at any moment in time to
collect and graph some data for an amount of time. It is
recommended to use the <option>--rel</option> switch in this
case.
</para>
<para>
Bootchart does not require root privileges, and will happily run
as a normal user.
</para>
<para>
Bootchart graphs are by default written time-stamped in
<filename>/run/log</filename> and saved to the journal with
<varname>MESSAGE_ID=9f26aa562cf440c2b16c773d0479b518</varname>.
Journal field <varname>BOOTCHART=</varname> contains the
bootchart in SVG format.

</varlistentry>
<varlistentry>
<term><emphasis>Started as a standalone program</emphasis></term>
<listitem><para>One can execute
<command>systemd-bootchart</command> as normal application
from the command line. In this mode, it is highly recommended
to pass the <option>-r</option> flag in order to not graph the
time elapsed since boot and before systemd-bootchart was
started, as it may result in extremely large graphs. The time
elapsed since boot might also include any time that the system
was suspended.</para></listitem>

<para><command>systemd-bootchart</command> generates SVG graphs.
In order to render those on a graphical display any SVG capable
viewer can be used. It should be noted that the SVG render engines
in most browsers (including Chrome and Firefox) are many times
faster than dedicated graphical applications like Gimp and
Inkscape. Just point your browser at

<title>History</title>
<para>This version of bootchart was implemented from scratch, but
is inspired by former bootchart incantations:</para>
<variablelist>
<varlistentry>
<term><emphasis>Original bash</emphasis></term>
<listitem><para>The original bash/shell code implemented
bootchart. This version created a compressed tarball for
processing with external applications. This version did not
graph anything, only generated data.</para></listitem>
</varlistentry>
<varlistentry>
<term><emphasis>Ubuntu C Implementation</emphasis></term>
<listitem><para>This version replaced the shell version with a
fast and efficient data logger, but also did not graph the
data.</para></listitem>
</varlistentry>
<varlistentry>
<term><emphasis>Java bootchart</emphasis></term>
<listitem><para>This was the original graphing application for
charting the data, written in java.</para></listitem>
</varlistentry>
<varlistentry>
<term><emphasis>pybootchartgui.py</emphasis></term>
<listitem><para>pybootchart created a graph from the data
collected by either the bash or C version.</para></listitem>
</varlistentry>
</variablelist>
<para>The version of bootchart you are using now combines both the
data collection and the charting into a single application, making
it more efficient and simpler. There are no longer any timing
issues with the data collector and the grapher, as the graphing
cannot be run until the data has been collected. Also, the data
kept in memory is reduced to the absolute minimum needed.</para>

<para>systemd-bootchart does not get the model information for the
hard drive unless the root device is specified with
<code>root=/dev/sdxY</code>. Using UUIDs or PARTUUIDs will boot
fine, but the hard drive model will not be added to the
chart.</para>
