New upstream release includes fixes for the following security issues:
* CVE-2017-3140: With certain RPZ configurations, a response with TTL 0 could
cause named to go into an infinite query loop
* CVE-2017-3142: An error in TSIG handling could permit unauthorized zone
transfers or zone updates.
* CVE-2017-3143: An error in TSIG handling could permit unauthorized zone
transfers or zone updates.

This change includes fixes for several security issues:
* CVE-2017-3138: rndc "" could trigger an assertion failure in named.
* CVE-2017-3137: Some chaining (i.e., type CNAME or DNAME) responses to
upstream queries could trigger assertion failures.
* CVE-2017-3136: dns64 with break-dnssec yes; can result in an assertion
failure.
* CVE-2017-3135: If a server is configured with a response policy zone
(RPZ) that rewrites an answer with local data, and is also configured
for DNS64 address mapping, a NULL pointer can be read triggering a
server crash.
* CVE-2016-9444: named could mishandle authority sections with missing
RRSIGs, triggering an assertion failure.
* CVE-2016-9131: named mishandled some responses where covering RRSIG
records were returned without the requested data, resulting in an
assertion failure.
* CVE-2016-9131: named incorrectly tried to cache TKEY records which could
trigger an assertion failure when there was a class mismatch.
* CVE-2016-8864: It was possible to trigger assertions when processing
responses containing answers of type DNAME.
* CVE-2016-6170: Added the ability to specify the maximum number of
records permitted in a zone (max-records #;). This provides a mechanism
to block overly large zone transfers, which is a potential risk with
slave zones from other parties.
* CVE-2016-2776: It was possible to trigger an assertion when rendering a
message using a specially crafted request.
* CVE-2016-2775: Calling getrrsetbyname() with a non absolute name could
trigger an infinite recursion bug in lwresd or named with lwres
configured if, when combined with a search list entry from resolv.conf,
the resulting name is too long.

This change fixes multiple denial-of-service vulnerabilities:
* CVE-2016-9131: A malformed response to an ANY query can cause an
assertion failure during recursion
* CVE-2016-9147: An error handling a query response containing
inconsistent DNSSEC information could cause an assertion failure
* CVE-2016-9444: An unusually-formed DS record response could cause
an assertion failure
* CVE-2016-9778: An error handling certain queries using the
nxdomain-redirect feature could cause a REQUIRE assertion failure
in db.c

If libjson-c is detected during bind-libs configure phase, bind-libs
will be built with libjson support. This results in a missing dependency
error during install phase. Solve this by disabling libjson support.

This patch removes some autoconf goo which is causing bind to use the host's ar
instead the ar from the toolchain. If they're both elf platforms this is fine,
but it's no good if host is darwin.
