63f28cad3e tmpfiles: split tmp.conf out
tmp.conf was dealing with 2 different kind of paths: one dealing with general
temporary paths such as /var/tmp and /tmp and the other one dealing with
temporary directories owned by systemd.

If for example a user wants to adjust the age argument of the general paths
only, he had to overload the whole file which is cumbersome and error prone
since any future changes in tmp.conf shipped by systemd will be lost.

So this patch splits out tmp.conf so the systemd directories are dealt
separately in a dedicated conf file. It's named "systemd-tmp.conf" based on the
naming recommendation made in tmpfiles.d man page.

In practice it shouldn't cause any regression since it's very unlikely that
users override paths owned by systemd.

dc7621a571 tmpfiles: automatically remove old private tmp dirs after reboot
Let's automatically destory per-unit private temporary directories, as
they are created by PrivateTmp=yes on each boot, if we notice them to be
around, in case they are left-overs from the last boot.

Fixes: #4401

822cd60135 tmpfiles.d: change all subvolumes to use quota
Let's make sure the subvolumes we create fit into a sensible definition
of a quota tree.

814f000872 tmpfiles.d: upgrade a couple of directories we create at boot to subvolumes
In particular we upgrade /var/lib/container, /var/tmp and /tmp to
subvolumes.

6b46ea73e3 namespace: include boot id in private tmp directories
This way it is easy to only exclude directories from the current boot
from automatic clean up in /var/tmp.

Also, pick a longer name for the directories so that are globs in
tmp.conf can be simpler yet equally accurate.

87267de89d tmpfiles: adjust excludes for the new per-service private dirs
In d8c9d3a (systemd: use unit name in PrivateTmp directories)
I forgot to update the tmpfiles config.

d34cd37490 Make PrivateTmp dirs also inaccessible from the outside
Currently, PrivateTmp=yes means that the service cannot see the /tmp
shared by rest of the system and is isolated from other services using
PrivateTmp, but users can access and modify /tmp as seen by the
service.

Move the private /tmp and /var/tmp directories into a 0077-mode
directory. This way unpriviledged users on the system cannot see (or
modify) /tmp as seen by the service.

5430f7f2bc relicense to LGPLv2.1 (with exceptions)
We finally got the OK from all contributors with non-trivial commits to
relicense systemd from GPL2+ to LGPL2.1+.

Some udev bits continue to be GPL2+ for now, but we are looking into
relicensing them too, to allow free copy/paste of all code within
systemd.

The bits that used to be MIT continue to be MIT.

The big benefit of the relicensing is that closed source code may now
link against libsystemd-login.so and friends.

f08fce8820 tmpfiles: Move /tmp and /var/tmp to a separate tmpfiles.d file to ease overrides via /etc
Many people prefer to avoid clearing /tmp and /var/tmp, and
distributions often have explicit settings for how often to clear them
if at all.  Overriding those with systemd currently requires overriding
all of /usr/lib/tmpfiles.d/systemd.conf via
/etc/tmpfiles.d/systemd.conf, copying across all the other entries, and
updating that override when systemd.conf changes.

Move the /tmp and /var/tmp entries from systemd.conf to a separate
tmp.conf, making them easier to override without affecting the rest of
systemd.conf.
