Fix proto for gethostent to match reality (takes void args)

Restore gethostent() as a supported interface. Yes, it maybe obsolete

struct netnet.n_net used to be an unsigned long integer.

In XNS5, and subsequently in POSIX-2001 it was changed to socklen_t.

To accomodate for this while preserving binary compatibility with the
old interface, prepend or append 32 bits of padding, depending on
the (LP64 data model) architecture's endianness. Fixes PR
standards/21411 from Ben Harris.

This should be deleted the next time the libc major number is

Patches provided by Joel Baker in PR 22270, verified by myself.

Header cleanup:
* IPv6 functions are in POSIX-2001, so make them visible there.
* freehostent(), getipnodebyaddr() and getipnodebyname() are _only_ in
XNS5.2, so don't expose them to XSH6 or POSIX applications.

Add a new feature-test macro, _NETBSD_SOURCE. If this is defined
by the application, all NetBSD interfaces are made visible, even
if some other feature-test macro (like _POSIX_C_SOURCE) is defined.
<sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE,
_POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve
existing behaviour.

This has two major advantages:
+ Programs that require non-POSIX facilities but define _POSIX_C_SOURCE
can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS.
+ It makes most of the #ifs simpler, in that they're all now ORs of the
various macros, rather than having checks for (!defined(_ANSI_SOURCE) ||
!defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place.

I've tried not to change the semantics of the headers in any case where
_NETBSD_SOURCE wasn't defined, but there were some places where the
current semantics were clearly mad, and retaining them was harder than
correcting them. In particular, I've mostly normalised things so that
_ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE,
_XOPEN_SOURCE and _NETBSD_SOURCE in that order.

* Since we actually only need size_t to be defined, nuke the previous inclusion
of <sys/types.h> and define size_t via <machine/ansi.h>.
* Various namespace protection issues, using XNS5.2 D2.0 as a reference.

define IPv6 library functions and structures, as defined in
RFC2292 and RFC2553.
define internal state structure for IPv6-transport resolver.

Commits for source code will follow.

* Remove the inclusion of <sys/param.h>; the most common use for this was

database lookup operations, and which pollutes name space.
* Per XSH98, provide symbols from <inttypes.h>.
* Add various bits of name space protection.
