r282071:

Integrate tools/regression/mqueue into the FreeBSD test suite as
tests/sys/mqueue

r282074:

Integrate tools/regression/aio/aiotest and tools/regression/aio/kqueue into the
FreeBSD test suite as tests/sys/aio

r282133:

Fill in the copyright boilerplate for the test program

r282134:

Add initial (unpolished) macros for interfacing with the FreeBSD test suite

This is very rough, but will be replaced/redesigned some time soon after I fix
the Jenkins breakage I introduced

r282135:

Use ATF_REQUIRE_KERNEL_MODULE instead of aio_available function

r282136:

- Use ATF_REQUIRE_KERNEL_MDOULE to require aio(4)
- Don't use /tmp as a basis for temporary files as it's outside of the ATF
sandbox
- Don't override MAX macro in sys/param.h

r282137:

Use PLAIN_REQUIRE_KERNEL_MODULE to require "mqueuefs"

r282138:

Adjust CFLAGS to find freebsd_test_suite/macros.h

Integrate tools/regression/aio/aiotest and tools/regression/aio/kqueue into the
FreeBSD test suite as tests/sys/aio

Integrate tools/regression/aio/aiotest into the FreeBSD test suite as tests/sys/aio

Integrate more tests into the FreeBSD test suite from tools/regression, etc

Cleanup and do minor refactoring before converting testcases to ATF

- Convert errx(-1, ..) to errx(1, ..)
- Move the aio(4) checks to a single function (aio_available); use modfind(2)
instead of depending on SIGSYS (doesn't work when aio(4) support is missing,
not documented in the aio syscall manpages).
- Use aio_available liberally in the testcase functions
- Use mkstemp(3) + unlink(2) instead of mktemp(3)
- Fix some -Wunused warnings
- Bump WARNS to 6

NO_MAN= has been deprecated in favor of MAN= for some time, go ahead
and finish the job. ncurses is now the only Makefile in the tree that
uses it since it wasn't a simple mechanical change, and will be
addressed in a future commit.

Style: NO_MAN doesn't need any value.

Start the dreaded NOFOO -> NO_FOO conversion.

OK'ed by: core

Add a basic aio functionality regression test, which simply writes and
then reads from a fairly broad range of object types: regular file,
fifo, UNIX socketpair, pty, UNIX pipe, and an md device. Not a deep
test of functionality, just a basic test that aio_write followed by
aio_read returns the correct data in a relatively timely manner.
