Lennart Poettering 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These lines are generally out-of-date, incomplete and unnecessary.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.

<title>Description</title>
<para><command>systemd-cgls</command> recursively shows the
contents of the selected Linux control group hierarchy in a tree.
If arguments are specified, shows all member processes of the
specified control groups plus all their subgroups and their
members. The control groups may either be specified by their full
file paths or are assumed in the systemd control group hierarchy.
If no argument is specified and the current working directory is
beneath the control group mount point
<filename>/sys/fs/cgroup</filename>, shows the contents of the
control group the working directory refers to. Otherwise, the full
systemd control group hierarchy is shown.</para>
<para>By default, empty control groups are not shown.</para>
