netdb.h: re-enable EAI_ADDRFAMILY, EAI_NODATA

EAI_ADDRFAMILY and EAI_NODATA are not in RFC 3493, but are available
and used in many other systems. It is desirable to have at least one
of them in order to distinguish between names that do not resolve and
those that do not have the requested address type. A change to
getaddrinfo() will use EAI_ADDRFAMILY. Both were "#if 0"; re-enable,
conditioned on __BSD_VISIBLE, and update comments. Also add comments
and __BSD_VISIBLE conditional for the last three EAI errors, which
are not in the RFC or POSIX. Note, all of these are available in
NetBSD and OpenBSD, and EAI_ADDRFAMILY and EAI_NODATA are available
in Linux (glibc).

gai_strerror() - Update string error messages according to RFC 3493.

Error messages in gai_strerror(3) vary largely among OSs.

For new software we largely replaced the obsoleted EAI_NONAME and
with EAI_NODATA but we never updated the corresponding message to better
match the intended use. We also have references to ai_flags and ai_family
which are not very descriptive for non-developer end users.

Bring new new error messages based on informational RFC 3493, which has
obsoleted RFC 2553, and make them consistent among the header adn
manpage.

include: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

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.

Implement an NSS backend for netgroups and add getnetgrent_r(3).

This support appears to have been documented in nsswitch.conf(5) for some
time. The implementation adds two NSS netgroup providers to libc. The
default, compat, provides the behaviour documented in netgroup(5), so this
change does not make any user-visible behaviour changes. A files provider
is also implemented.

innetgr(3) is implemented as an optional NSS method so that providers such
as NIS which are able to implement efficient reverse lookup can do so.
A fallback implementation is used otherwise. getnetgrent_r(3) is added for
convenience and to provide compatibility with glibc and Solaris.

With a small patch to net/nss_ldap, it's possible to specify an ldap
netgroup provider, allowing one to query nisNetgroupTriple entries.
