Also extend the test to allow testing of an external stpncpy

The four functions more or less perform the same operation.
Reuse the same unit test with slight changes so we can cover
them all. Constant-time operation is not verified for the

Extend the tests to permit loading an external memcmp function
and testing it over using the libc version. This was added by the
example of other tests in the test suite doing the same thing and
helped tremendously in development.
This change was originally part of D41442 but was taken out to
permit separate review as extrapolated from @ngie's request in
D41349.

position of the string against a certain position of the set.

Add a strverscmp(3) function to libc, a GNU extension I implemented by
reading its glibc manual page. It orders strings following a much more
natural ordering (e.g. "ent1 < ent2 < ent10" as opposed to
"ent1 < ent10 < ent2" with strcmp(3)'s lexicographic ordering).
Also add versionsort(3) for use as scandir(3)'s compar argument.
Update manual page for scandir(3) and add one for strverscmp(3).

abort_handler_s() currently simply calls abort(), though the standard
specifies more: "Writes an implementation-defined message to stderr
which must include the string pointed to by msg and calls abort()."
memset_s() is missing error condition "n > smax", and does not invoke
the constraint handler after filling the buffer: "following errors are
detected at runtime and call the currently installed constraint
handler function after storing ch in every location of the destination
range [dest, dest+destsz) if dest and destsz are themselves valid",
one of the errors is "n > smax" itself.

when importing collation support from Dragonfly/Illumos amdmi3@ tested the
collation branch and reported an issue with Russian collation. John Marino fixed
the issue in Dragonfly and I merged it back to FreeBSD.
Now that Illumos is working on merging our fixes they (Lauri Tirkkonen) found
issues with the commit that fixes the russian collation in UTF-8 that resulted
in a crash with strxfrm(3) and the ISO-8859-5 locale (fixed in FreeBSD r302916).
This small test was written to ensure we do not bring back the old issue with
russian collation while fixing the other issue.

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.

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
