* dirmngr/dns.h (dns_quietinit): Remove.
(dns_hints_i_new): Remove.
--
Even before our change, dns_quietinit was questionable macro; There
was no place in dns.c which requires overrides in initializer list.
Only redundant zero were.

(cherry picked from commit 371ae25f8f)
* dirmngr/dns.h (DNS_OPTS_INIT, dns_opts): Remove.
* dirmngr/dns-stuff.c (libdns_res_open): Use zero-ed, and initialized
automatic variable for opts.
* dirmngr/dns.c (send_query, resolve_query, resolve_addrinfo):
Likewise.
--
In fact, DNS_OPTS_INIT was only needed when args are none. With
partially specified initialization, C99 guarantees zero-ed other
members just like static object.

(cherry picked from commit d661acd483)
* dirmngr/dns.h (dns_rr_foreach): Don't use dns_rr_i_new.
Call dns_rr_grep with NULL.
* dirmngr/dns.c (dns_rr_grep): Support NULL for error_.
--
Here we still use C99 feature of struct member initialization in
dns_rr_foreach, for struct dns_rr_i. Note that in C99, it guarantees
non-specified member fields are initialized by zero. So, there's no
need to use dns_rr_i_new at all.
