Currently, the recv_fix_encryption_hierarchy() function accepts
'destsnap' as one of its parameters. Originally, this was intended
to be the top-level dataset of a receive (whether or not the
receive was recursive). Unfortunately, this parameter actually is
simply the input that is passed in from the command line. When
the user specifies 'zfs recv -d', this string is actually only the
name of the receiving pool since the rest of the name is derived
from the send stream. This causes the function to fail, leaving
some datasets with an invalid encryption hierarchy.
This patch resolves this problem by passing in the top_zfs variable
instead. In order to make this work, this patch also includes some
changes that ensure the value is always present when we need it.

Currently the best way to wait for the completion of a long-running
operation in a pool, like a scrub or device removal, is to poll 'zpool
status' and parse its output, which is neither efficient nor convenient.
This change adds a 'wait' subcommand to the zpool command. When invoked,
'zpool wait' will block until a specified type of background activity
completes. Currently, this subcommand can wait for any of the following:
- Scrubs or resilvers to complete
- Devices to initialized
- Devices to be replaced
- Devices to be removed
- Checkpoints to be discarded
- Background freeing to complete
For example, a scrub that is in progress could be waited for by running
zpool wait -t scrub <pool>
This also adds a -w flag to the attach, checkpoint, initialize, replace,
remove, and scrub subcommands. When used, this flag makes the operations
kicked off by these subcommands synchronous instead of asynchronous.
This functionality is implemented using a new ioctl. The type of
activity to wait for is provided as input to the ioctl, and the ioctl
blocks until all activity of that type has completed. An ioctl was used
over other methods of kernel-userspace communiction primarily for the
sake of portability.
Porting Notes:
This is ported from Delphix OS change DLPX-44432. The following changes
were made while porting:
- Added ZoL-style ioctl input declaration.
- Reorganized error handling in zpool_initialize in libzfs to integrate
better with changes made for TRIM support.
- Fixed check for whether a checkpoint discard is in progress.
Previously it also waited if the pool had a checkpoint, instead of
just if a checkpoint was being discarded.
- Exposed zfs_initialize_chunk_size as a ZoL-style tunable.
- Updated more existing tests to make use of new 'zpool wait'
functionality, tests that don't exist in Delphix OS.
- Used existing ZoL tunable zfs_scan_suspend_progress, together with
zinject, in place of a new tunable zfs_scan_max_blks_per_txg.
- Added support for a non-integral interval argument to zpool wait.
Future work:
ZoL has support for trimming devices, which Delphix OS does not. In the
future, 'zpool wait' could be extended to add the ability to wait for
trim operations to complete.

/usr/bin/env python3 is the suggested[1] shebang for Python in general
(likewise for python2) and is conventional across platforms. This eases
development on systems where python is not installed in /usr/bin
(FreeBSD for example) and makes it possible to develop in virtual
environments (venv) for isolating dependencies.
Many packaging guidelines discourage the use of /usr/bin/env, but since
this is the canonical way of writing shebangs in the Python community,
many packaging scripts are already equipped to handle substituting the
appropriate absolute path to python automatically.
Some RPM package builders lacking brp-mangle-shebangs need a small
fallback mechanism in the package spec to stamp the appropriate shebang
on installed Python scripts.

To resolve the issue we cache the system's hostid when initializing

Currently, the noop receive code fails to work with raw send streams
and resuming send streams. This happens because zfs_receive_impl()
reads the DRR_BEGIN payload without reading the payload itself.
Normally, the kernel expects to read this itself, but in this case
the recv_skip() code runs instead and it is not prepared to handle
the stream being left at any place other than the beginning of a
record.
This patch resolves this issue by manually reading the DRR_BEGIN
payload in the dry-run case. This patch also includes a number of
small fixups in this code path.

Remove a lot of unnecessary setting and incrementing of `i`.
Remove unused variable `j`.
Instead of calling out to Python in a loop to generate the same string
repeatedly, generate the string once using shell constructs before
entering the loop.

md5sum in particular but also sha256sum to a lesser extent is used
in several areas of the test suite for computing checksums. The vast
majority of invocations are followed by `| awk '{ print $1 }'`.
Introduce functions to wrap up `md5sum $file | awk '{ print $1 }'` and
likewise for sha256sum. These also serve as a convenient interface for
alternative implementations on other platforms.

TRUE and FALSE happen to be defined, but we should use B_TRUE and
B_FALSE for the sake of consistency.
