 It will help if we add an internal backend crypto module (used from
 libcryptolink) for environments where Botan is not available.  It will
 also be helpful for users who don't need any crypto related DNS
 operations (no TSIG, no DNSSEC) and don't want to install Botan just
 to compile BIND 10.

 This should be configurable in configure.ac and should be disabled by
 default.  It was also suggested that if the null module is enabled a
 warning message (that no TSIG or DNSSEC will be usable) be shown.

 Note also that when the null module is enabled some unit tests will
 fail.  We'll need to work around it in some way.
