Thanks to Tony Finch for the program and the performance figure.
* New internal consistency checking with assert if right options set.
* New adns_wait_poll function like adns_wait but uses poll, not select.
- * New adnshost utility - currently only a usage message :-).
+ * New adnshost utility - very alpha.
+ * New adns_errtypeabbrev function.
Incompatible changes:
* RRs with mailboxes never rejected due to strange chars if _raw.
* Lack of a mailbox produces `.' not `<>'.
* Better usage messages (and no default query domain) for adnstest.
* Return EAGAIN from _check instead of EWOULDBLOCK.
+ * adns_rr_info on _r_mx etc. shows status type abbrev and status number.
Bugfixes:
* Do not invoke __autosys indirectly from __procdgram (result: coredump
