/etc/netconfig is required by the tirpc library which nscd and several
other programs use.

The Samba package used by the INVIS server (based on openSUSE) needs
some additional Samba permissions for the added ActiveDirectory /
Kerberos support.
As discussed with Seth, add /var/lib/sss/mc/initgroups read permissions
to abstractions/nameservice instead of only to the smbd profile because
it's probably needed by more than just Samba if someone uses sss.

- change abstractions/postfix-common to allow /etc/postfix/*.db k
- add several permissions to postfix/error, postfix/lmtp and postfix/pipe
- remove superfluous abstractions/kerberosclient from all postfix
profiles - it's included via abstractions/nameservice

The updated rule covers the old-style /usr/lib/firefox/firefox.sh
wrapper and the current /usr/lib/firefox{,-esr}/firefox{,-esr} paths.
It is a tiny bit wide but let's lean on the side of compatibility with
whatever similar paths are used in the future. It doesn't grant access
to anything we don't want on a current Debian sid system.

Based on Cameron Norman's initial work
(http://bazaar.launchpad.net/~cameronnemo/apparmor/gnome-abstraction/revision/3111) with the following changes:
* don't include GTK+ 3.0 configuration: already done earlier
* generalize to future GLib versions
* support /usr/local
* allow reading the parent directory as well, following the lead
of usr.lib.telepathy: this is harmless and could be needed in some cases.
Description: adjust the multiarch alternation rule in the perl abstraction for
modern Debian and Ubuntu systems which store some modules under the
architecture-specific perl-base directory instead of perl or perl5.

/run/systemd/journal/dev-log but journald offers both:
- a native journal API at /run/systemd/journal/socket (see sd_journal_print(4))
- /run/systemd/journal/stdout for connecting a program's output to the journal
(see systemd-cat(1)).
In addition to systemd-cat, the stdout access is required for nested container
(eg, LXD) logs to show up in the host. Interestingly, systemd-cat and LXD
containers require 'r' in addtion to 'w' to work. journald does not allow
reading log entries from this socket so the access is deemed safe.

glibc implements this by doing a readdir() and filtering.
We already allowed sysconf(_SC_NPROCESSORS_ONLN), which is
basically a read from /sys/devices/system/cpu/online.

nmbd needs some additional permissions:
- k for /var/cache/samba/lck/* (via abstractions/samba)
- rw for /var/cache/samba/msg/ (the log only mentioned r, but that
directory needs to be created first)
- w for /var/cache/samba/msg/* (the log didn't indicate any read access)

openSUSE uses "php7" (not just "php") in several paths, so also allow that.

This should solve the "overlapping rules with conflicting 'x'
modifiers" problem (introduced with r3594) entirely.
The other options I could think of were:
* ix → Pix, adjust all profiles that do 'ix' accordingly, and leave
alone those that do Pix already; downsides: requires updating quite
a few profiles all around the place, and breaks a mere "file," rule;
* ix → Pix, adjust all profiles that do 'ix' accordingly, and change
the "file," rule semantics to imply Pix; downside: very intrusive,
and likely to break random existing policy in ways that are hard
to predict;
* stick to ix, and adjust all profiles that do anything else with
overlapping rules, to do ix instead; downside: in some cases this means
removing the 'P' modifier, which can cause regressions in how we confine
stuff.
I've looked up in the bzr history to understand why execution rights
would be needed, and… the answer predates the move to bzr.
Looking into the SVN history, if it's even available anywhere, is
a bit too much for me, so I've tested this change and the few
applications I've tried did not complain. Of course, more testing will
be needed.
Having consistent x modifiers in this abstraction is needed
to allow profiles including abstractions/base to apply x rules
overlapping with several of the rules from the base abstraction.
E.g. one may need to have rules applying to /**, for example because
a mere "file," conflicts with the ix→Pix change I did in r3596.
The latest glibc (including nscd) in openSUSE Tumbleweed comes with
glibc-2.3.3-nscd-db-path.diff: Move persistent nscd databases to
/var/lib/nscd
This needs updates (adding /var/lib/nscd/) to abstractions/nameservice
and the nscd profile.

This is the least invasive solution to the problem I'm trying to solve
right now (Evince not starting in GNOME on Wayland, and probably
similar issues for other GNOME applications I suppose).
At some point, we will probably want to source the wayland abstraction
from other desktop environments' abstractions, or simply from the
X one. Let's come back to it once people using these other desktop
environments on Wayland with AppArmor enabled tell us what policy
change is needed to make it work for them.
