implement MINFO. Why you ask? MINFO is one of the original RFC1035 types, and can thus be compressed. NSD does such compression, and if we don't support MINFO we fail to decompress it.
activate MINFO, thanks Jelte
add MINFO to qtypes
drop no-op flag strict-rfc-axfrs, thanks Jelte
also drop strict-rfc-axfrs from pdns.conf-dist
report TXT only once, thanks @zeha
implement RKEY record type. No regression test since none have ever been spotted in the wild, so we don't know what to compare against.
