Merge Backport xdg open

@Talkless requested xdg-open and friends be cherry-picked into 2.13

This is the set of commits (and fixes) to do that without modifying them.

We could drop backporting dbus-strict by modifying both the adding missing .d dirs, and add xdg-open and friends patches.

This series does not currently include the make check test and its fixes for the .d directories, as they were not required but we may want to include them to catch any potential errors.

Add xdg-open (and friends) abstraction

Implement set of abstractions to handle opening uris via xdg-open and similar helpers used on different desktop environments.

Abstractions are intended to be included into child profile, together with bundle abstractions such as ubuntu-browsers, ubuntu-email and others, for fine-grained control on what confined application can actually open via xdg-open and similar helpers.

abstractions: add /etc/mdns.allow to /etc/apparmor.d/abstractions/mdns

In focal users of mdns get denials in apparmor confined applications.
An exampel can be found in the original bug below.

It seems it is a common pattern, see
https://github.com/lathiat/nss-mdns#etcmdnsallow

Therefore I'm asking to add
   /etc/mdns.allow r,
to the file
   /etc/apparmor.d/abstractions/mdns"
by default.

--- original bug ---

Many repetitions of

audit: type=1400 audit(1585517168.705:63): apparmor="DENIED" operation="open" profile="/usr/sbin/chronyd" name="/etc/mdns.allow" pid=1983815 comm="chronyd" requested_mask="r" denied_mask="r" fsuid=123 ouid=0

in log. I use libnss-mdns for .local name resolution, so /etc/nsswitch.conf contains

hosts: files mdns [NOTFOUND=return] myhostname dns

and /etc/mnds.allow contains the domains to resolve with mDNS (in may case, "local." and "local"; see /usr/share/doc/libnss-mdns/README.html.)

Presumably cronyd calls a gethostbyX() somewhere, thus eventually trickling down through the name service switch and opening /etc/mdns.allow, which the AppArmor profile in the chrony package does not allow.

Merge: abstractions/nameservice: allow accessing /run/systemd/userdb/

On systems with systemd 245, `nss-systemd` additionally queries NSS records from `systemd-userdbd.service`. See https://systemd.io/USER_GROUP_API/ .

This does not bring full support for `systemd-homed`, but I don't use that service so I can't help with that.

Merge from trunk revision 1805:

  Attached is a patch to make the initscript not fail if /tmp is full
  by converting the comm(1) usage on temporary files to an embedded
  awk script. On both Ubuntu and OpenSUSE, a version of awk (mawk in
  Ubuntu, gawk in OpenSUSE) is either a direct or indirect dependency
  on the minimal or base package set, and the original reporter also
  mentioned that an awk-based solution would be palatable in a way
  that converting to bash, or using perl or python here would not be.

  In the embedded awk script, I've tried to avoid gawk or mawk
  specific behaviors or extensions; e.g. this is the reason for the
  call to sort on the output of the awk script, rather than using
  gawk's asort(). But please let me know if you see anything that
  shouldn't be portable across awk implementations.

  An additional issue that is fixed in both scripts is handling
  child profiles (e.g. hats) during reload. If child profiles are
  filtered out (via grep -v '//') of the list to consider, then
  on reloading a profile where a child profile has been removed or
  renamed, that child profile will continue to stick around. However,
  if the profile containing child profiles is removed entirely,
  if the initscript attempts to unload the child profiles after the
  parent is removed, this will fail because they were unloaded when
  the parent was unloaded. Thus I removed any filtering of child
  profiles out, but do a post-awk reverse sort which guarantees that
  any child profiles will be removed before their parent is. I also
  added the LC_COLLATE=C (based on the Ubuntu version) to the sort
  call to ensure a consistent sort order.

  To restate, the problem with the existing code is that it creates
  temporary files in $TMPDIR (by default /tmp) and if that partition
  is full, problems with the reload action ensue. Alternate solutions
  include switching the initscript to use bash and its <$() extension
  or setting TMPDIR to /dev/shm/. The former is unpalatable to some
  (particularly for an initscript), and for the latter, /dev/shm is
  only guaranteed to exist on GNU libc based systems (glibc apparently
  expects /dev/shm to exist for its POSIX shared memory implementation;
  see shm_overview(7)). So to me, awk (sans GNU extensions) looks
  to be the least bad option here.
