r261550 (by glebius):

Add test case for kern/181741. Right now test fails.

PR: 181741
Sponsored by: Nginx, Inc.

r281354:

Fix warnings, fix a typo in a testcase description, bump WARNS to 3

- Remove argc/argv (-Wunused)
- Cast len in comparison to size_t (-Wsign-compare)

Sponsored by: EMC / Isilon Storage Division

r281355:

Fix -Wunused warnings, bump WARNS to 6

The testcase fails today on subtest # 9

The output is still broken if prove -rv is run and the testcase aborts
prematurely (the testcase doesn't really conform to TAP protocol properly,
except when it completes fully)

r281358:

- Parameterize out the number of accept/connect attempts
- Randomize the bind port to allow 2+ consecutive calls in < 10 minutes, and
to also not fail if (for instance) there's a server already listening on port
8080
- Don't leak the listening socket / fds into the child process

-- Remove argc/argv (-Wunused)
-- Mark sig __unused (-Wunused)

Correct several nits/problems in the unix_close_race regression test.

Submitted by: Mikolaj Golub <to.my.trociny at gmail.com>
MFC after: 3 days

Add unix_close_race, a regresion test to catch ENOTCONN being returned
improperly from one of two instances of close(2) being called
simultaneously on both ends of a connected UNIX domain socket. The test
tool is slightly tweaked to improve failure modes, and while often does
trigger the problem, doesn't do so consistently due to the nature of the
race.
