Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

libc: do not include <sys/types.h> where <sys/param.h> was already included

According to style(9):
> normally, include <sys/types.h> OR <sys/param.h>, but not both.
(<sys/param.h> already includes <sys/types.h> when LOCORE is not defined).

Use ANSI C prototypes. Eliminates -Wold-style-definition warnings.

Update our stub resolver to final version of libbind.

Obtained from: ISC

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
wrong value if excessively large netmasks are
supplied. [RT #18512]

Reported by: Maksymilian Arciemowicz <cxib__at__securityreason.com>

Merge BIND 9.4.1 into main chunk.

MFC after: 2 weeks

__p_rcode_syms is declared as external in resolv.conf, so it cannot be
redeclared as static in res_debug.c.

Make __p_rcode_syms global and add it to Symbol map. The rest of
__p_??_syms are already global.

Choice of FBSD_1.0 version for these debug symbols seems strange and
should be revisited before symbol versioning is enabled for libc.so.7.

Per Regents of the University of Calfornia letter, remove advertising
clause.

- Merge our local changes.
