Make getnameinfo(3) salen requirement less strict and
document details of salen in getnameinfo(3) manual page.

getnameinfo(3) returned EAI_FAIL when salen was not equal to
the length corresponding to the value specified by sa->sa_family.
However, POSIX or RFC 3493 does not require it and RFC 4038
Sec.6.2.3 shows an example passing sizeof(struct sockaddr_storage)
to salen.

This change makes the requirement less strict by accepting
salen up to sizeof(struct sockaddr_storage). It also includes
two more changes: one is to fix return values because both SUSv4
and RFC 3493 require EAI_FAMILY when the address length is invalid,
another is to fix sa_len dependency in PF_LOCAL.

Add NI_NUMERICSCOPE.

POSIX also declares NI_NUMERICSCOPE, which makes getnameinfo() return a
numerical scope identifier. The interesting thing is that support for
this is already present in code, but #ifdef disabled. Expose this
functionality by placing a definition for it in <netdb.h>.

While there, remove references to NI_WITHSCOPEID, as that got removed 11
years ago.

Add PF_LOCAL support in getaddrinfo(3) and getnameinfo(3):

- In a PF_LOCAL address, "hostname" must begins with '/' and "servname"
is always NULL. All of ai_flags are ignored.

- PF_UNSPEC matches PF_LOCAL. EAI_SERVICE is not returned to make
AF-independent programming easier; "servname" is always ignored
in PF_LOCAL. In practice, PF_INET* and PF_LOCAL are
mutually-exclusive because a hostname which begins with '/' is invalid
in PF_INET*. No domain name resolution is performed for a PF_LOCAL address.
