Automake can perform program name transformations at install time.
However, arc_summary has its own name transformation taking place,
which interferes with the automake transforms. The automake transforms
must be taken into account in order to resolve the conflict.

This matches the behavior of other python scripts, such as arcstat and
dbufstat, which are always installed but whose install-exec-hook actions
will simply touch up the shebang if a python interpreter was configured
*and* that interpreter is a python2 interpreter.
Fixes installation in a minimal build chroot without python available.

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.

Add new script arc_summary3.py as a complete rewrite of the
arc_summary.py tool (see issue #6873)
Add new options:
-g/--graph - Display crude graphic representation
of ARC status and quit
-r/--raw - Print all available information as
minimally formatted list (for grep)
-s/--section - Print a single section. This
replaces -p/--page, which is kept for
backwards use but marked as
depreciated
Add new sections with information on ZIL and SPL. Notify user
if sections L2ARC and VDEV are skipped instead of failing
silently. Add warning that -p/--page option is depreciated.
Developed for Python 3.5.

Build products from an out of tree build should be written
relative to the build directory. Sources should be referred
to by their locations in the source directory.
This is accomplished by adding the 'src' and 'obj' variables
for the module Makefile.am, using relative paths to reference
source files, and by setting VPATH when source files are not
co-located with the Makefile. This enables the following:
$ mkdir build
$ cd build
$ ../configure \
--with-spl=$HOME/src/git/spl/ \
--with-spl-obj=$HOME/src/git/spl/build
$ make -s
This change also has the advantage of resolving the following
warning which is generated by modern versions of automake.
Makefile.am:00: warning: source file 'xxx' is in a subdirectory,
Makefile.am:00: but option 'subdir-objects' is disabled

The arc_summary script is a useful utility for administrators on
other ZFS platforms. It provides a quick and easy way to get a high
level view of the current ARC state.
Historically this was a perl script but it was rewritten in python
for FreeNAS. We've decided to adopt the python version instead of
the perl version for a few reasons.
1) ZoL has no existing perl dependencies, but it does have a python
dependency for scripts such as arcstat.py and dbufstat.py. Using
python for arc_summary.py helps us minimize dependencies.
2) Most major Linux distributions already depend heavily on python
for their core infrastructure. This means it's very likely to
be available even very early in the boot process.
