Add several permissions to the dovecot profiles that are needed on ubuntu
(surprisingly not on openSUSE, maybe it depends on the dovecot config?)
As discussed some weeks ago, the added permissions use only /run/
instead of /{var/,}run/ (which is hopefully superfluous nowadays).

The dovecot/auth profile needs access to /run/dovecot/anvil-auth-penalty
and /var/spool/postfix/private/auth.
The dovecot/log profile needs the attach_disconnected flag.

- dovecot/auth: allow to read stats-user
- dovecot/config: allow to read /usr/share/dovecot/**
- dovecot/imap: allow to ix doveconf, read /etc/dovecot/ and
/usr/share/dovecot/**
These things were reported by Félix Sipma in Debian Bug#835826
(with some help from sarnold on IRC)

Also allow reading ~/.dovecot.svbin (that's the default filename in the
dovecot config) in dovecot/lmtp profile.
(*.svbin files can probably also appear inside @{DOVECOT_MAILSTORE}, but
that's already covered by the existing rules.)

Since the latest openSUSE Tumbleweed update (dovecot 2.2.21 -> 2.2.22),
dovecot/auth writes to /var/run/dovecot/stats-user.

Darix' guess is that this is needed by libpq because he uses a postgresql
database with dovecot and has ssl enabled in postgresql.

- usr.lib.dovecot.auth needs /{var/,}run/dovecot/auth-token-secret.dat{,.tmp} rw,
- usr.lib.dovecot.imap requests block_suspend, which I propose to deny as usual

user/password files (everybody will use a different filename for the
user/password list - and when you allow reading the password list,
allowing to read the config doesn't add any harm ;-)

Some updates for the dovecot profiles, based on a patch from
Christian Wittmer <chris@computersalat.de> (he sent it as SR for the
openSUSE package, which uses a slightly older version of the dovecot
profiles)
Fix problems with dovecot and managesieve:
* usr.lib.dovecot.managesieve-login: network inet6 stream
* usr.lib.dovecot.managesieve:
+#include <tunables/dovecot>
/usr/lib/dovecot/managesieve {
+ capability setgid, # covered by abstractions/dovecot-common, therefore not part of this patch
+ capability setuid,
+ network inet stream,
+ network inet6 stream,
+ @{DOVECOT_MAILSTORE}/ rw,
+ @{DOVECOT_MAILSTORE}/** rwkl,
* add #include <abstractions/wutmp> to usr.lib.dovecot.auth
apparmor="DENIED" operation="open" parent=18310 \
profile="/usr/lib/dovecot/auth" name="/var/run/utmp" pid=20939 \
comm="auth" requested_mask="r" denied_mask="r" fsuid=0 ouid=0

This commit adds a dovecot-common abstraction, as well as adjusting
the profiles for dovecot's helper binaries to make use of it. The
important addition is the ability for the dovecot master process to
send signals to the helpers.

abstractions/mysql.
This binary/profile seems to be the only one that needs to do this, so
add it to this profile (instead of abstractions/mysql) to avoid superfluous
permissions for other programs with abstractions/mysql
