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

Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!

$ ./configure
$ make pkg
