Several issues related to strange mount/umount behavior were reported and this commit should address most of them. The original idea was to put in place a zfs mount helper (mount.zfs). This helper is used to enforce 'legacy' mount behavior, and perform any extra mount argument processing (selinux, zfsutil, etc). This helper wasn't ready for the 0.6.0-rc1 release but with this change it's functional but needs to extensively tested. This change addresses the following open issues. Closes #101 Closes #107 Closes #113 Closes #115 Closes #119
