r313439:

Merge content from ^/projects/netbsd-tests-upstream-01-2017 into ^/head

The primary end-goal of this drop is ease future merges with NetBSD and
collaborate further with the NetBSD project.

The goal was (largely, not completely as some items are still oustanding
in the NetBSD GNATS system) achieved by doing the following:
- Pushing as many changes required to port contrib/netbsd-tests
back to NetBSD as possible, then pull the upstream applied changes
back in to FreeBSD.
- Diff reduce with upstream where possible by:
-- Improving libnetbsd header, etc compat glue.
-- Using _SED variables to modify test scripts on the fly for items
that could not be upstreamed to NetBSD.

As a bonus for this work, this change also introduces testcases for
uniq(1).

Many thanks to Christos for working with me to get many of the changes
back into the NetBSD project.

r314450:

Add additional __FreeBSD_version guards around the hsearch_r testcases

The reasoning for this is the same as r276046: to ease MFCing the tests
to ^/stable/10 .

This was accidentally missed in r313439

MFC r311925,r311968,r311969,r312102,r312108:

r311925:

Import testcase updates with code contributed back to NetBSD

This also (inadvertently) contains an update to
contrib/netbsd-tests/lib/libc/sys/t_wait.c (new testcases).

In collaboration with: christos@NetBSD.org

r311968:

Fix lib/libc/sys/access_test after r311925

sys/param.h needs to be #included in order for __FreeBSD_version to be checked

r311969:

Remove __HAVE_LONG_DOUBLE #define from t_strtod.c and place it in Makefile

This is to enable support in other testcases

Inspired by lib/msun/tests/Makefile .

r312102:

Note that sys/types.h is required on FreeBSD for kqueue(2), unlike NetBSD

r312108:

Delete trailing whitespace and use __arraycount instead of nitems in contrib code

MFC r311250:

mincore_resid: free buf after use

CID: 978304

MFC r309837:

Change the process limits for RLIMIT_MEMLOCK to RLIM_INFINITY when
executing :mincore_resid

The default process limits in FreeBSD is 64kB for unprivileged users,
which empirically is too low to run the :mincore_resid testcase.

Process limits are inherited, so even though the default limit for
root users is RLIM_INFINITY, the inherited limit with "sudo" with the
default login.conf will be 64kB.

Use setrlimit to set rlim_max for RLIMIT_MEMLOCK to RLIM_INFINITY to
avoid ENOMEM issues when calling mlock to wire the mmap'ed address
space.

setrlimit requires root access to increase rlim_max, so require root
privileges when running the test

Discovered when executing the tests with sudo, e.g.
"sudo kyua test -k /usr/tests/lib/libc/sys/Kyuafile mincore_test"

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Remove expected failure from lib.libc.sys.t_mincore:mincore_resid

The failure was added based on observation seen on 11.0-CURRENT @ r273153, not
based on internal testing at EMC/Isilon

PR: 194829
Tested with the following configuration:
- amd64/i386
- 11.0-CURRENT @ r273153
- 100 times in a tight loop as root with the following commands...
-- kyua test lib/libc
-- kyua test lib/libc/sys
-- kyua test lib/libc/sys/mincore_test

Port t_mincore to FreeBSD

Mark :mincore_resid as atf_tc_expect_fail on FreeBSD because of new bug
discovered in running the tests (it succeeded from earlier on in the year to
September/October on FreeBSD, at least)
