This commit ensures that the snapcraft icon is shown in the lock screen notifications. Unfortunately, to make it work it requires to be modified in the .deb package; it seems that there is no way of doing this in the snap package because the required change must be set in the "first" .desktop file, and /usr/share(/applications) is before than /var/lib/snapd/desktop(/applications) in the XDG_DATA_DIRS order.
Jira: DT-862
Use systemd-tmpfiles to create the private tmp mount namespace root
dir (/tmp/snap-private-tmp) on boot as owned by root with restrictive
permissions. We can use this as a known location to then create per-snap
private tmp mount namespace dirs (/tmp/snap-private-tmp/snap.$SNAP_INSTANCE)
etc.

`snapd.mounts-pre.target` will be before any mount unit,
`snapd.mounts.target`. Now we can schedule before or after mounts
without needing to modify the mount units.
We also install those mounts to `snapd.mounts.target` so that we can
make snapd.service for example, "want" all mounts.
The implementation of these services is not yet ready, but in order to
be able to deliver it in a snap package, we need to have at least the
service files installed on the system by the distribution package.
These stubs just reexecute the binaries from the snap.
* tests: add spread test for reexec of prompt services
* packaging: update distros for prompt services
Ship them in Debian and Ubuntu, remove them elsewhere.
* cmd: update error message with unimplemented prompt services
* tests: do not disable prompt-reexec tests in UC
* many: disable prompting for 14.04
The kernel changes will most likely not land there.
* many: install prompt services for Ubuntu Core
* tests: exclude UC16 from reexec-prompt test
The services are installed, but disabled; enabling them is not trivial
and not worth the effort, since prompting will most likely not be
backported there.
* wrappers/core18: don't fail if the prompt service is missing in snapd
This fixes a spread failure in the tests/core/snapd-refresh-vs-services
test, where we install an old version of snapd (2.49) which does not
have the Prompt service.
* tests: fix typo in comment
Thanks @pedronis.
* cmd: add license header
Thanks @Meulengracht
Commit 5545f79af9 introduced a check for
WSL that causes our spread tests (in particular, selinux-clean) to fail
on Fedora and CentOS.
Add the rules from `audit2allow -a` to the SELinux rules, to suppress
those warnings.
This fixes an error occurring in our spread tests on Centos:

Note that with this change we are not removing the call to
miscfiles_read_all_certs(snappy_t)
because it was actually present twice in this file.
When collecting preseeded data, include also snapd/mounts.
This directory contains layout info and is essential to have
a correct layout functionality on preseeded system.

Snapd installs bash completion files from snaps in
`/usr/share/bash-completion/completions` which in some distributions
is a read-only filesystem.
Instead of installing them in `/usr` we can install them within
`/var/lib/snapd` which should always be writable.
Because `/var/lib/snapd/desktop` is already in `XDG_DATA_DIRS`, we can
save the files there.
Because bash-completion 2.1 and prior do not support `XDG_DATA_DIRS`,
on older distributions, the legacy path
`/usr/share/bash-completion/completions` will still be used.

* cmd/snap-update-ns/change.go: sort needed, desired and not reused mount entries
Sort new mount entries by their mimic creation directories, such that the mimic
directories that end up being created are done so in lexographical order.
Also update a single unit test where there were multiple mimic directories
being created because now all mount entries that create mimic directories are
performed first.

* cmd/snap-update-ns/change.go: stop using experimental flag
This experimental flag is not necessary anymore, and in fact is actively
harmful in that it is causing snaps to crash when they are running and an
update happens either to snapd or to their content snap dependencies and we end
up completely discarding the per-snap namespace, which leads to some
destructive effects inside the "sort of inheriting" per-user namespaces, that
then later do not get undone and thus recreated in the per-user namespace as
those namespaces aren't properly setup to inherit the constructive updates.

* cmd/snap-update-ns: remove old implementation
It's not used anymore, so we can just delete this code wholesale.

* cmd/snap-update-ns: unconditionally perform the "overname" mounts first
* cmd/snap-update-ns: ignore errors on unexisting mounts
When unmounting, we can get the EINVAL error if the given mount point
does not exist. Previously, this code was handling this fine for the
umount() syscall, but we do also need the same logic when attempting to
remount a mount as private.
* data/selinux: update policy to allow more mounts
When supporting appstream-metadata interface, snap-update-ns will mount
directories labeled as usr_t (eg. /usr/share/metainfo, /usr/share/appdata) and
fwdupd_cache_t (eg. /var/cache/app-info).

* tests/regression/lp-1855596: test parallel installs + $SNAP/... layouts too
Test that with parallel installs and layouts which trigger mounts on top of
$SNAP/... (which itself will be an overname mount in a parallel install snap)
still work and we can still refresh such mount setups.
This is successful because we always handle overname mounts first when creating
the mounts and any such mounts underneath the overname are then ordered
properly.

* tests: remove duplicate tests
With commit df6bbd5c64d2820836e74039726a10dfe844cd91
(cmd/snap-update-ns/change.go: stop using experimental flag) a bunch of
tests which were nearly identical save for the fact that they were
exercising different implementations of the NeededChanges() function,
have become exact duplicates, since now there's only one implementation.
So, let's keep only one copy of them.
* cmd/snap-update-ns: add unit test for existing directories

of the paths already exist.

* tests/mounts-persist-refresh-content-snap: regression test for firefox crash
This ensures that files which are shared via mounts in the MountConnectedPlug
method in an interface like the desktop interface remain shared in the per-user
mount namespace when the content snap is refreshed (not the main snap itself
even). We don't expect this situation to happen much when refresh app awareness
is fully enabled by default, but it is still important to test that the
snap-update-ns isn't horribly breaking apps when refreshes happen to take place
when apps are still running (this could be the case for desktop systems which
have a running app for more than 14 days for example).

* tests/mounts-persist-refresh-content-snap: fix firefox crash regression test
To actually reproduce the crash, we need to use layouts with sources from the
files that the content interface is sharing with the snap.
Additionally, create the fonts dir and restart snapd before installing the
snap, actually exit 1 if the process died and kill the parent process last with
the other child processes in the restore section, and fix the shellcheck issue.

waste too much time waiting for processes to exit.
