e169749fc0 Correct exit code for dbufstat -v and arcstat -v
Both scripts were returning an error code of 1
when using the -v argument. -v should exit with
an error code of 0.

7cf2ffa020 Make arc_summary.py and dbufstat.py compatible with python3
To make arc_summary.py and dbufstat.py compatible with python3
some minor fixes were required, this was done automatically by
`2to3 -w arc_summary.py` and `2to3 -w dbufstat.py`.

a6c6e0f583 Remove "index" column from dbufstat.py
Commit ca0bf58d to address arcs_mtx contention removed column "index"
from the output of kstats/dbuf.

dbufstat.py was not updated to reflect this, which causes it to crash
when run with -bx

This removes "index" from hardcoded lists of columns.

d738d34da5 Add dbufstat.py command
The dbufstat.py command was added to provide a conveniant way to
easily determine what ZFS is caching.  The script consumes the
raw /proc/spl/kstat/zfs/dbufs kstat data can consolidates it in
to a more human readable form.  This was designed primarily as
a tool to aid developers but it may also be useful for advanced
users who want more visibility in to what the ARC is caching.

When run without options dbufstat.py will default to showing a
list of all objects with at least one buffer present in the
cache.  The total cache space consumed by that object will be
printed on the right along with the object type.  Similar to the
arcstats.py command the -x option may used to display additional
fields.

Two other modes of operation are also supported by dbufstat.py
and the expectation is additional display modes may be added as
needed.  The -t option will summerize the total number of bytes
cached for each object type, and the -b option will show every
dbuf currently cached.

The script was designed to be consistent with arcstat.py and
includes most of the same options and funcationality.
