Scot W. Stevenson 19528cf949 Add Python 3 rewrite of arc_summary.py
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.

Turbo Fredriksson 47a4a6fd5f Support parallel build trees (VPATH builds)
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

cburroughs edd5b80d07 Add arc_summary.py from FreeNAS
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.
