Initial dirmngr policy module
    
    Ported from Debian with changes
    
    Dirmngr is a server for managing and downloading certificate revocation
    lists (CRLs) for X.509 certificates and for downloading the certificates
    themselves. Dirmngr also handles OCSP requests as an alternative to
    CRLs. Dirmngr is either invoked internally by gpgsm (from GnuPG 2) or
    when running as a system daemon through the dirmngr-client tool.
