Add a clock_nanosleep() syscall, as specified by POSIX.
Make nanosleep() a wrapper around it.
Attach the clock_nanosleep test from NetBSD. Adjust it for the
FreeBSD behavior of updating rmtp only when interrupted by a signal.
I believe this to be POSIX-compliant, since POSIX mentions the rmtp
parameter only in the paragraph about EINTR. This is also what
Linux does. (NetBSD updates rmtp unconditionally.)
Copy the whole nanosleep.2 man page from NetBSD because it is complete
and closely resembles the POSIX description. Edit, polish, and reword it
a bit, being sure to keep any relevant text from the FreeBSD page.

Back in 2015 when I reimplemented these functions to use an AVL tree, I
was annoyed by the weakness of the typing of these functions. Both tree
nodes and keys are represented by 'void *', meaning that things like the
documentation for these functions are an absolute train wreck.
To make things worse, users of these functions need to cast the return
value of tfind()/tsearch() from 'void *' to 'type_of_key **' in order to
access the key. Technically speaking such casts violate aliasing rules.
I've observed actual breakages as a result of this by enabling features
like LTO.
I've filed a bug report at the Austin Group. Looking at the way the bug
got resolved, they made a pretty good step in the right direction. A new
type 'posix_tnode' has been added to correspond to tree nodes. It is
still defined as 'void' for source-level compatibility, but in the very
far future it could be replaced by a proper structure type containing a
key pointer.

This is the backing feature to implement C++11 thread storage duration
specified by the thread_local keyword. A destructor for given
thread-local object is registered to be executed at the thread
termination time using __cxa_thread_atexit(). Libc calls the
__cxa_thread_calls_dtors() during exit(3), before finalizers and
atexit functions, and libthr calls the function at the thread
termination time, after the stack unwinding and thread-specific key
destruction.
There are several uncertainties in the API which lacks a formal
specification. Among them:
- is it allowed to register destructors during destructing;
we allow, but limiting the nesting level. If too many iterations
detected, a diagnostic is issued to stderr and thread forcibly
terminates for now.
- how to handle destructors which belong to an unloading dso;
for now, we ignore destructor calls for such entries, and
issue a diagnostic. Linux does prevent dso unload until all
threads with destructors from the dso terminated.
It is supposed that the diagnostics allow to detect real-world
applications relying on the above details and possibly adjust
our implementation. Right now the choices were to provide the slim
API (but that rarely stands the practice test).
Tests are added to check generic functionality and to specify some of
the above implementation choices.

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.
(WITH_SYSTEM_COMPILER: Enable by default) and it's prerequisite: r300354,
caused i386 builds to fail when cross-built on an amd64 host.

src is an array. Remove these tests for NULL pointers.
While I'm here, eliminate a strlcpy with a correct but suspicious-looking
calculation for the third parameter (i.e. not a simple sizeof).
Compare the strings in-place instead of copying.

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.
