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.

mincore_resid: free buf after use

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"
