Giuseppe Di Natale 5e021f56d3 Add dbuf hash and dbuf cache kstats
Introduce kstats about the dbuf hash and dbuf cache
to make it easier to inspect state. This should help
with debugging and understanding of these portions
of the codebase.

Correct format of dbuf kstat file.

Introduce a dbc column to dbufs kstat to indicate if
a dbuf is in the dbuf cache.

Introduce field filtering in the dbufstat python script.

Introduce a no header option to the dbufstat python script.

Introduce a test case to test basic mru->mfu list movement
in the ARC.
