backword compatibility with 3.0.x releases - restored
* glusterfs.h - added back the removed 'fop' types in same order * call-stub.c - enhanced logging in case of failure * server-protocol.c - added a ENOSYS function for these fops, so there will be no crash if a old client connects to mainline server. Signed-off-by: Amar Tumballi <amar@gluster.com> Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 734 (keep only the working/usable code in build tree to focus more on development) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=734
