certmap: add new library libsss_certmap

With this library it would be possible to map certificates and users not
only by adding the full certificate to the user's LDAP object but by
adding e.g. only parts like the issuer and subject name. Additionally
the library is also able to flexible select/match certificates based on
values in the certificate.

Details about mapping and matching rules can be found in the included
man page.
