#1641: Further bug(s) in NSEC3 RDATA implementation

 Its toText() crashes for this input:
 {{{
 1 1 1 5CA1AB1E QBREATAE625G9UGNH0BOAAS79IT1LTPE NS SOA RRSIG DNSKEY
 NSEC3PARAM TYPE65534
 }}}

 From a quick look it's due to difference on this part between NSEC and
 NSEC3 implementations:

 {{{#!c++
         // NSEC
         assert(len > 0 && len <= 32);

         // NSEC3
         assert(len >= 0 && len < 32);
 }}}

 but we should not just fix this specific case, but try to unify the
 bitmap related processing between these two classes more (that's
 partially done), through which we may find other remaining bugs.
 We'll also need more tests.
