This avoids the need for all users to customize secure path on their system. - Updated ZoL infrastructure to manage constrained path - Updated all test cases - Check permissions for usergroup tests - When testing in-tree create links under bin/ - Update fault cleanup such that missing files during cleanup aren't fatal. - Configure su environment with constrained path OpenZFS-issue: https://www.illumos.org/issues/7290 OpenZFS-commit: https://github.com/openzfs/openzfs/commit/1d32ba6 Closes #5903

# Description:
|
|
# Verify that nopwrite is not enabled if the copies property changes
|
|
#
|
|
# Strategy:
|
|
# 1. Create a clone with copies set higher than the origin fs
|
|
# 2. Verify that nopwrite is in use.
|
|
# 3. Repeat with the number of copies decreased.
