cluster/afr: Pipeline the "full" data self-heal read-write loop.
Start upto "data-self-heal-window-size" instances of the read-write loop of the "full" data self-heal algorithm simultaneously. Add a new option "data-self-heal-window-size" with range [1-1024], and a default value of 16. Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 320 (Improve self-heal performance) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=320
