Saso Kiselkov 3a17a7a99a Illumos #3137 L2ARC compression 
3137 L2ARC compression
Reviewed by: George Wilson <george.wilson@delphix.com>
Reviewed by: Matthew Ahrens <mahrens@delphix.com>

Notes for Linux port:

A l2arc_nocompress module option was added to prevent the
compression of l2arc buffers regardless of how a dataset's
compression property is set.  This allows the legacy behavior
to be preserved.
