as the more common /usr/lib/dovecot.

Begin preparing policy for the 4.0 release. This may result in new
denials. This is expected and needed to make sure policy is ready
for the 4.0 release.

Host files accessed by tcp_wrapper can reference other files, from man
5 hosts.allow
```
A string that begins with a '/' character is treated as a file name. A host name or address is matched if it matches any host name or address pattern listed in the named file. The file format is zero or more lines with zero or more host name or address patterns separated by whitespace. A file name pattern can be used anywhere a host name or address pattern can be used.
```
This means adding a file to hosts requires updating multiple profiles
Add a hosts abstraction so users only have to modify a single location.

Tag profiles and abstractions with abi information.
Tagging abstractions is not strictly necessary but allows the parser
to detect when their is a mismatch and that policy will need an
update for abi.
We do not currently tag the tunables because variable declarations
are not currently affected by abi.

Also adjust the signal rules in the dovecot-common and apache2-common
abstractions to match the profile names, and to really do that
(peer=...{bin,sbin}... didn't work, the correct syntax would have been
peer=...\{bin,sbin\}...)
This fixes the regression introduced by !149 / commit
4200932d8f
On current Debian sid it needs to read
/usr/share/dovecot/protocols.d/imapd.protocol, which is not surprising given it
already needed read access to /usr/share/dovecot/protocols.d/.
dovecot-lda needs
- the attach_disconnected flags
- read access to /usr/share/dovecot/protocols.d/
- rw for /run/dovecot/auth-userdb

dovecot-lda needs to read and write /tmp/dovecot.lda.*.
It also needs to be able to execute sendmail to send sieve vacation
mails.
For now, I'm using a child profile for sendmail to avoid introducing a
new profile with possible regressions. This child profile is based on
the usr.sbin.sendmail profile in extras and should cover both postfix'
and sendmail's sendmail.
I also mixed in some bits that were needed for (postfix) sendmail on my
servers, and dropped some rules that were obsolete (directory rules not
ending with a /) or covered by an abstraction.
In the future, we might want to provide a stand-alone profile for
sendmail (based on this child profile) and change the rule in the
dovecot-lda profile to Px.

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.
