This extends our sysfs '/sys/module/zfs' entry to include feature
and property attributes. The primary consumer of this information
is user processes, like the zfs CLI, that need to know what the
current loaded ZFS module supports. The libzfs binary will consult
this information when instantiating the zfs and zpool property
tables and the pool features table.
This introduces 4 kernel objects (dirs) into '/sys/module/zfs'
with corresponding attributes (files):
features.runtime
features.pool
properties.dataset
properties.pool
