Import capsicum-test into ^/vendor/google/capsicum-test/dist

The following change imports google/capsicum-test@9333154 from GitHub, omitting
the embedded version of googletest, as well as the incomplete libcasper.

This test suite helps verify capsicum(3) support via functional tests
written in the GoogleTest test framework.

Kernel support for capsicum(4) is tested by side-effect of testing
capsicum(3).

NB: as discussed in a previous [closed] PR [1], the casper(3) tests are
incomplete/buggy and will not pass on FreeBSD. Thus, I have no intention of
integrating them into the build/test on FreeBSD as-is.

The import command used was:
```
curl -L https://github.com/google/capsicum-test/tarball/9333154 | tar --strip-components=1 -xvzf - -C dist/
rm -Rf dist/*/
```

Import GoogleTest 1.8.1 into the vendor tree under `^/google/googletest/dist`

GoogleTest is a widely used opensource C++ test framework, licensed under a
BSD 3-clause license. It fits best in the realm of doing functional/whitebox
testing, similar to ATF's C++ library. However, it has additional functionality
such as per-testcase setup fixtures, class level setup and teardown fixtures,
and a lot more functional/syntactic goodness.

In addition to large corporations adopting GoogleTest as their defacto C++ test
library (Facebook, Google, etc), many opensource projects have adopted
GoogleTest, e.g., the Capsicum project, Chrome, etc.

The goal for importing this is to enable testing with zfsd and integrate
googletest into kyua.

This is the final version that will support a pre-C++-11 compiler. As such, this
test framework will not be available to gcc 4.2.1, similar to ATF's C++ library.

A subsequent set of commits will:

1. Tag ^/google/googletest/dist as ^/google/googletest/1.8.1 using `svn cp ^/google/googletest/dist ^/google/googletest/1.8.1`.
2. Import this code into ^/head and integrate it into the build for all applicable
platforms and C++ compile toolchains.

The import was done via the following command pipeline on OSX:
```
curl -L https://github.com/google/googletest/archive/release-1.8.1.tar.gz | tar --strip-components=1 -xvzf - -C dist/
```

pyzfs: python3 support (build system)

Almost all of the Python code in the respository has been updated
to be compatibile with Python 2.6, Python 3.4, or newer. The only
exceptions are arc_summery3.py which requires Python 3, and pyzfs
which requires at least Python 2.7. This allows us to maintain a
single version of the code and support most default versions of
python. This change does the following:

* Sets the default shebang for all Python scripts to python3. If
only Python 2 is available, then at install time scripts which
are compatible with Python 2 will have their shebangs replaced
with /usr/bin/python. This is done for compatibility until
Python 2 goes end of life. Since only the installed versions
are changed this means Python 3 must be installed on the system
for test-runner when testing in-tree.

* Added --with-python=<2|3|3.4,etc> configure option which sets
the PYTHON environment variable to target a specific python
version. By default the newest installed version of Python
will be used or the preferred distribution version when
creating pacakges.

* Fixed --enable-pyzfs configure checks so they are run when
--enable-pyzfs=check and --enable-pyzfs=yes.

* Enabled pyzfs for Python 3.4 and newer, which is now supported.

* Renamed pyzfs package to python<VERSION>-pyzfs and updated to
install in the appropriate site location. For example, when
building with --with-python=3.4 a python34-pyzfs will be
created which installs in /usr/lib/python3.4/site-packages/.

* Renamed the following python scripts according to the Fedora
guidance for packaging utilities in /bin

- dbufstat.py -> dbufstat
- arcstat.py -> arcstat
- arc_summary.py -> arc_summary
- arc_summary3.py -> arc_summary3

* Updated python-cffi package name. On CentOS 6, CentOS 7, and
Amazon Linux it's called python-cffi, not python2-cffi. For
Python3 it's called python3-cffi or python3x-cffi.

* Install one version of arc_summary. Depending on the version
of Python available install either arc_summary2 or arc_summary3
as arc_summary. The user output is only slightly different.

a common.sh with in-tree path information from the common.sh.in
template. This file and sourced by the test scripts and used
for in-tree testing, it is not included in the packages. When
building packages 'make install' uses the same template to
create a new common.sh which is appropriate for the packaging.

* Removed unused functions/variables from scripts/common.sh.in.
Only minimal path information and configuration environment
variables remain.

* Remaining shell scripts in the scripts directory updated to
cleanly pass shellcheck and added to checked scripts.

Porting Notes:
- Utilities which aren't available under Linux have been removed.
- Because of sudo's default secure path behavior PATH must be
explicitly reset at the top of libtest.shlib. This avoids the
need for all users to customize secure path on their system.
- Updated ZoL infrastructure to manage constrained path
- Updated all test cases
- Check permissions for usergroup tests
- When testing in-tree create links under bin/
- Update fault cleanup such that missing files during
cleanup aren't fatal.
- Configure su environment with constrained path
