Copying the approach chosen in r309412. This fixes building the libc tests
on a macOS host since the macOS /bin/dd binary does not support status=none.
As there only seem to be two uses, this commit changes the two Makefiles.
If this becomes more common, we could also add a wrapper bootstrap script
that ignores status= and forwards the remaining args to the real dd.
Another alternative would be to remove the status flag and pipe stderr to
/dev/null, but them we lose error messages.

These testcases exercise a number of functional requirements for sendfile(2).
The testcases use IPv4 and IPv6 domain sockets with TCP, and were confirmed
functional on UFS and ZFS. UDP address family sockets cannot be used per the
sendfile(2) contract, thus using UDP sockets is outside the scope of
testing the syscall in positive cases. As seen in
`:s_negative_udp_socket_test`, UDP is used to test the sendfile(2) contract
to ensure that EINVAL is returned by sendfile(2).
The testcases added explicitly avoid testing out `SF_SYNC` due to the
complexity of verifying that support. However, this is a good next logical
item to verify.
The `hdtr_positive*` testcases work to a certain degree (the header
testcases pass), but the trailer testcases do not work (it is an expected
failure). In particular, the value received by the mock server doesn't match
the expected value, and instead looks something like the following (using
python array notation):
`trailer[:]message[1:]`
instead of:
`message[:]trailer[:]`
This makes me think there's a buffer overrun issue or problem with the
offset somewhere in the sendfile(2) system call, but I need to do some
other testing first to verify that the code is indeed sane, and my
assumptions/code isn't buggy.
The `sbytes_negative` testcases that check `sbytes` being set to an
invalid value resulting in `EFAULT` fails today as the other change
(which checks `copyout(9)`) has not been committed [1]. Thus, it
should remain an expected failure (see bug 232210 for more details
on this item).
Next steps for testing sendfile(2):
1. Fix the header/trailer testcases so that they pass.
2. Setup if_tap interface and test with it, instead of using "localhost", per
@asomers's suggestion.
3. Handle short recv(2)'s in `server_cat(..)`.
4. Add `SF_SYNC` support.
5. Add some more negative tests outside the scope of the functional contract.

Previously, libc.so would initialize its notion of the break address
using _end, a special symbol emitted by the static linker following
the bss section. Compatibility issues between lld and ld.bfd could
cause the wrong definition of _end (libc.so's definition rather than
that of the executable) to be used, breaking the brk()/sbrk()
interface.
Avoid this problem and future interoperability issues by simply not
relying on _end. Instead, modify the break() system call to return
the kernel's view of the current break address, and have libc
initialize its state using an extra syscall upon the first use of the
interface. As a side effect, this appears to fix brk()/sbrk() usage
in executables run with rtld direct exec, since the kernel and libc.so
no longer maintain separate views of the process' break address.

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.

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.

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
