Zbigniew Jędrzejewski-Szmek 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.

<title>Description</title>
<para>In addition to the error names user programs define, D-Bus
knows a number of generic, standardized error names that are
listed below.</para>
<para>In addition to this list, in sd-bus, the special error
namespace <literal>System.Error.</literal> is used to map
arbitrary Linux system errors (as defined by <citerefentry
project='man-pages'><refentrytitle>errno</refentrytitle><manvolnum>3</manvolnum></citerefentry>)
to D-Bus errors and back. For example, the error
<constant>EUCLEAN</constant> is mapped to
<literal>System.Error.EUCLEAN</literal> and back.</para>
