dovecot-auth-proxy: replace directory traversal with LDAP lookups.
This provides better isolation opportunity as the service doesn't need
to run as ‘vmail’ user. We use a dedicated system user instead, and
LDAP ACLs to limit its access to the strict minimum.
The new solution is also more robust to quoting/escaping, and doesn't
depend on ‘home=/home/mail/virtual/%d/%n’ (we might use $entryUUID
instead of %d/%n at some point to make user renaming simpler).
OTOH we no longer lists users that have been removed from LDAP but still
have a mailstore lingering around. This is fair.
