Brian Behlendorf 6a8f9b6bf0 Enforce ARC meta-data limits 
This change ensures the ARC meta-data limits are enforced.  Without
this enforcement meta-data can grow to consume all of the ARC cache
pushing out data and hurting performance.  The cache is aggressively
reclaimed but this is a soft and not a hard limit.  The cache may
exceed the set limit briefly before being brought under control.

By default 25% of the ARC capacity can be used for meta-data.  This
limit can be tuned by setting the 'zfs_arc_meta_limit' module option.
Once this limit is exceeded meta-data reclaim will occur in 3 percent
chunks, or may be tuned using 'arc_reduce_dnlc_percent'.

Closes #193
