Issue #3878
The zfs range lock interface no longer tightly depends on a
znode_t and therefore can be used in ztest. This allows the
previous ztest specific implementation to be removed, and for
additional test coverage of the shared version.

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.

- In older systems without sysroot.mount, import before dracut-mount,
and re-enable old dracut mount hook
- rootflags MUST be present even if the administrator neglected to
specify it explicitly
- Check that mount.zfs exists in sbindir

Issue #4538
The receive_writer_arg and receive_arg structures become large
when ZFS is compiled with debugging enabled. This results in
gcc throwing an error about excessive stack usage:
module/zfs/dmu_send.c: In function ‘dmu_recv_stream’:
module/zfs/dmu_send.c:2502:1: error: the frame size of 1256 bytes is
larger than 1024 bytes [-Werror=frame-larger-than=]
Fix this by allocating those functions on the heap, rather than
on the stack.

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.

At the very least, the zfs_secpolicy_write_perms ioctl security policy
callback, which calls dsl_dataset_hold(), can require freeing memory and,
therefore, re-enter ZFS. This patch enables PF_FSTRANS for all of the
security policy callbacks similarly to the manner in which it's enabled
for the actual ioctl callback.
