Also zpool_get_prop is modified to don't add "%" or "x" if literal.

Issue #4023
Issue #4024
struct zvol_state contains a dummy znode, which is around 1KB on x64,
only for zfs_range_lock. But in reality, other than z_range_lock and
z_range_avl, zfs_range_lock only need znode on regular file, which
means we add 1KB on a structure and gain nothing.
In this patch, we remove the dummy znode for zvol_state. In order to
do that, we also need to refactor zfs_range_lock a bit. We move
z_range_lock and z_range_avl pair out of znode_t to form zfs_rlock_t.
This new struct replaces znode_t as the main handle inside the range
lock functions.
We also add pointers to z_size, z_blksz, and z_max_blksz so range lock
code doesn't depend on znode_t. This allows non-ZPL consumers like
Lustre to use the range locks with their equivalent znode_t structure.

Porting notes:
I removed ZoL's zpool_get_prop_literal() in favor of
zpool_get_prop(..., boolean_t literal) since that's what OpenZFS
uses. The functionality is the same.
Add a script designed to facilitate in-tree development and testing
by installing symlinks on your system which refer to in-tree helper
utilities. These helper utilities must be installed to in order to
exercise all ZFS functionality. By using symbolic links and keeping
the scripts in-tree during development they can be easily modified
and those changes tracked.
