libc/tests: add getaddrinfo test

A test suite for getaddrinfo(3) written in C. Unlike NetBSD test, this
one will be mostly focused on what the API should return when something
isn't good with your DNS. Test emulates bad DNS servers in resolv.conf
intercepting fopen(2) and emulates downed network intercepting send(2).

Initial version covers three main scenarios: all good, server(s) timed
out, network down. For each scenario we test hostname with trailing dot
and without, since libc resolver uses quite different code paths,
sometimes even yielding with different error codes. All current error
codes in the test are what our libc returns right now, meaning the test
documents what we have, not what there should be.

libc/tests: enable getaddrinfo(1) tests from NetBSD

Enable running of contrib/netbsd-tests/lib/libc/net/getaddrinfo without
modifications to the test program itself. However, create our own version
of expected results files. They are produced from the NetBSD files, with
the following list of changes:

o AF_INET6 value is different, hence: s/family 24/family 28/.
o SCTP result (socktype 5 protocol 132) needs to be added to many queries
results.
o NetBSD libc sorts multiple results first by protocol, then by address
family. FreeBSD first sorts on address family, then on protocol. Some
results need to be reordered.
o Error strings need to be fixed:
s/hostname nor servname provided, or not known/Name does not resolve/
s/ai_family not supported/Address family not recognized/
s/servname not supported for ai_socktype/\
Service was not recognized for socket type/.

Merge ^/user/ngie/release-pkg-fix-tests to unbreak how test files are installed
after r298107

Summary of changes:

- Replace all instances of FILES/TESTS with ${PACKAGE}FILES. This ensures that
namespacing is kept with FILES appropriately, and that this shouldn't need
to be repeated if the namespace changes -- only the definition of PACKAGE
needs to be changed
- Allow PACKAGE to be overridden by callers instead of forcing it to always be
`tests`. In the event we get to the point where things can be split up
enough in the base system, it would make more sense to group the tests
with the blocks they're a part of, e.g. byacc with byacc-tests, etc
- Remove PACKAGE definitions where possible, i.e. where FILES wasn't used
previously.
- Remove unnecessary TESTSPACKAGE definitions; this has been elided into
bsd.tests.mk
- Remove unnecessary BINDIRs used previously with ${PACKAGE}FILES;
${PACKAGE}FILESDIR is now automatically defined in bsd.test.mk.
- Fix installation of files under data/ subdirectories in lib/libc/tests/hash
and lib/libc/tests/net/getaddrinfo
- Remove unnecessary .include <bsd.own.mk>s (some opportunistic cleanup)

Document the proposed changes in share/examples/tests/tests/... via examples
so it's clear that ${PACKAGES}FILES is the suggested way forward in terms of
replacing FILES. share/mk/bsd.README didn't seem like the appropriate method
of communicating that info.

Add reachover Makefiles for contrib/netbsd-tests/lib/libc; this adds approximately
500 new testcases

Various TODOs have been sprinkled around the Makefiles for items that even need
to be ported (missing features), testcases have issues with building/linking, or
issues at runtime.

A variant of this code has been tested extensively on amd64 and i386
10-STABLE/11-CURRENT for several months without issue. It builds on other
architectures, but the code will remain off until I have prove it works on
virtual hardware or real hardware on other architectures
