[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Merge the resolver part of BIND 9.4.3 into HEAD.
It includes the following fix:

2426. [bug] libbind: inet_net_pton() can sometimes return the

supplied. [RT #18512]

Comment out the function prototypes which our libc actually
doesn't have.

Update the resolver in libc to BIND9's one.

Since, res_sendsigned(3) and the friends use MD5 functions, it is
hard to include them without having MD5 functions in libc. So,
res_sendsigned(3) is not merged into libc.

Since, res_update(3) in BIND9 is not binary compatible with our
res_update(3), res_update(3) is leaved as is, except some
necessary modifications.
The res_update(3) and the friends are not essential part of the
resolver. They are not defined in resolv.h but defined in
res_update.h separately in BIND9. Further, they are not called from
our tree. So, I hide them from our resolv.h, but leave them only
for binary backward compatibility (perhaps, no one calls them).

Since, struct __res_state_ext is not exposed in BIND9, I hide it
from our resolv.h. And, global variable _res_ext is removed. It
breaks binary backward compatibility. But, since it is not used from
outside of our libc, I think it is safe.

Decrease the value of RES_DFLRETRY from 4 to 2.

Don't declare ___res_ext() twice.

Add the macro RES_DFLRETRY long-promised by resolver(5).
It specifies the default number of retries per a name server.
This makes the code consistent with the manpage and allows to
kill another constant in res_init.c that should have been a
#define'd parameter. (This appears to be a case when the manpage
was better than the code, so the latter was to be fixed.)

PR: bin/62139 (in the audit trail)

Don't try to pass off a struct sockaddr as a struct sockaddr_in when it
may in fact very well be a struct sockaddr_in6. Just use plain struct
sockaddr.

This brings us yet another step closer to a clean -O2 build.

Make the resolver(3) and many associated interfaces much more reentrant.
The getaddrinfo(3), getipnodebyname(3) and resolver(3) can coincide now
with what should be totally reentrant, and h_errno values will now
be preserved correctly, but this does not affect interfaces such as
gethostbyname(3) which are still mostly non-reentrant.

In all of these relevant functions, the thread-safety has been pushed
down as far as it seems possible right now. This means that operations
that are selected via nsdispatch(3) (i.e. files, yp, dns) are protected
still under global locks that getaddrinfo(3) defines, but where possible
the locking is greatly reduced. The most noticeable improvement is
that multiple DNS lookups can now be run at the same time, and this
shows major improvement in performance of DNS-lookup threaded programs,
and solves the "Mozilla tab serialization" problem.

No single-threaded applications need to be recompiled. Multi-threaded
applications that reference "_res" to change resolver(3) options will
need to be recompiled, and ones which reference "h_errno" will also
if they desire the correct h_errno values. If the applications already
understood that _res and h_errno were not thread-safe and had their own
locking, they will see no performance improvement but will not
actually break in any way.

Please note that when NSS modules are used, or when nsdispatch(3)
defaults to adding any lookups of its own to the individual libc
_nsdispatch() calls, those MUST be reentrant as well.

Add support for timeout: and attempts: resolver options.

$Id$ -> $FreeBSD$

Remove the extern decl of ``h_errno''. It's already
externed in netdb.h - where all of its #define values
live. If anything requires h_errno here (nothing in
/usr/src seems to) it's almost definitely broken.

Damn, bind8 includes added <arpa/nameser.h> as a prerequisite for
<resolv.h>. This breaks user ppp at least, and goodness knows how
many ports. :-(

This a bit of a hack, but is probably simpler than duplicating the
typedefs and protecting them from each other.

Also, remove some temporary XXX notes that I forgot to remove before.

Update nameserver interface to bind-8.1.2 levels. We do not use IRS (yet?)

Note that this has more ugly symbol hiding and binary compatability hacks
that can go away the second we bump majors.
