Checking the first nibble of the IPv6 address to be 0 and then
excluding two well known cases (v4-mapped, loopback) leaves us with
more cases where the first nibble could be 0, e.g., the RFC 6052,
2.1 Well-Known Prefix 64:ff9b::/96.
It is not practical to track them all and it is not clear what lead
to this special casing originally, so remove them.
While here also remove the IN6_IS_ADDR_LINKLOCAL() + NI_NUMERICHOST
case as link-local address resolution does exist.
We do leave the IN6_IS_ADDR_MULTICAST() case for now as I could
not find any references to any official reverse lookups for these.
Adding comments for more case (and some historic behaviour) in order
to make it easier to follow the logic.

These system call wrappers call interposed system calls in fairly
trivial ways. Move them over to libsys so all __libsys_interposer
consumers end up in libsys.
Also move recvmmsg and sendmmsg as they are documented with recv and
send.

System calls or their wrappers are now interposed by
__libsys_interposing with purely libc entries remaining in
__libc_interposing.
Use __libsys_interposing_slot in libthr to update __libsys_interposing,
but also make __libc_interposing_slot fall back to
__libsys_interposing_slot so an out of date libc has a chance of working
during updates.

The section INTERNET ADDRESSES describes the acceptance of dotted
values with varying number of parts in multiple bases. This applies
to inet_aton and inet_addr, but not to inet_pton. Clarify this
section by listing the functions to which this applies. Move the
description of what inet_pton accepts into this section from STANDARDS,
where it is easily missed. Rename the section to clarify that it
applies only to IPv4. (inet_pton also works with IPv6.)

Rework getaddrinfo(3) to return different error values for unresolvable
names (same as before, EAI_NONAME) and those without a requested addr
(EAI_ADDRFAMILY) when using DNS. This is implemented via an added
error in the nsswitch layer, NS_ADDRFAMILY, which is used only by
getaddrinfo(). The error is passed through nsdispatch(3), but that
routine has no changes to handle this error. The error originates in
the getaddrinfo DNS layer called via nsdispatch(), and is processed
by the search layer that calls nsdispatch().
While here, add a little style to returns near those that were
modified.
