zfs create, receive and rename can bypass this hierarchy rule. Update
both userland and kernel module to prevent this issue and use pyzfs
unit tests to exercise the ioctls directly.
Note: this commit slightly changes zfs_ioc_create() ABI. This allow to
differentiate a generic error (EINVAL) from the specific case where we
tried to create a dataset below a ZVOL (ZFS_ERR_WRONG_PARENT).

* Updated unit tests to be compatbile with python 2 or 3. In most
cases all that was required was to add the 'b' prefix to existing
strings to convert them to type bytes for python 3 compatibility.
* There were several places where the python version need to be
checked to remain compatible with pythong 2 and 3. Some one
more seasoned with Python may be able to find a way to rewrite
these statements in a compatible fashion.

These changes are efficient and valid in python 2 and 3. For the
most part, they are also pythonic.
* 2to3 conversion
* add __future__ imports
* iterator changes
* integer division

Porting Notes:
* Additional changes to recv_rename_impl() were required due to
encryption code not being merged in OpenZFS yet.
* libzfs_core python bindings (pyzfs) were updated to fully support
both lzc_rename() and lzc_destroy()

One small integration that was absent from b52563 was
support for zfs recv -o / -x with regards to encryption
parameters. The main use cases of this are as follows:
* Receiving an unencrypted stream as encrypted without
needing to create a "dummy" encrypted parent so that
encryption can be inheritted.
* Allowing users to change their keylocation on receive,
so long as the receiving dataset is an encryption root.
* Allowing users to explicitly exclude or override the
encryption property from an unencrypted properties stream,
allowing it to be received as encrypted.
* Receiving a recursive heirarchy of unencrypted datasets,
encrypting the top-level one and forcing all children to
inherit the encryption.

__init__.py used by Python packages typically has nothing in it
including contrib/pyzfs/libzfs_core/test/__init__.py, however this
causes `make distclean` to delete the file.
This is the only file with size 0, and it seems reasonable to have
a comment to avoid being deleted, rather than trying to modify
distclean behavior.

This commit introduces several changes:
* Update LICENSE and project information
* Give a good PEP8 talk to existing Python source code
* Add RPM/DEB packaging for pyzfs
* Fix some outstanding issues with the existing pyzfs code caused by
changes in the ABI since the last time the code was updated
* Integrate pyzfs Python unittest with the ZFS Test Suite
* Add missing libzfs_core functions: lzc_change_key,
lzc_channel_program, lzc_channel_program_nosync, lzc_load_key,
lzc_receive_one, lzc_receive_resumable, lzc_receive_with_cmdprops,
lzc_receive_with_header, lzc_reopen, lzc_send_resume, lzc_sync,
lzc_unload_key, lzc_remap
Note: this commit slightly changes zfs_ioc_unload_key() ABI. This allow
to differentiate the case where we tried to unload a key on a
non-existing dataset (ENOENT) from the situation where a dataset has
no key loaded: this is consistent with the "change" case where trying
to zfs_ioc_change_key() from a dataset with no key results in EACCES.

libzfs_core is intended to be a stable interface for programmatic
administration of ZFS.
This wrapper provides one-to-one wrappers for libzfs_core API functions,
but the signatures and types are more natural to Python.
nvlists are wrapped as dictionaries or lists depending on their usage.
Some parameters have default values depending on typical use for
increased convenience.
Enumerations and bit flags become strings and lists of strings in
Python.
Errors are reported as exceptions rather than integer errno-style
error codes. The wrapper takes care to provide one-to-many mapping
of the error codes to the exceptions by interpreting a context
in which the error code is produced.
Unit tests and automated test for the libzfs_core API are provided
with this package.
Please note that the API tests perform lots of ZFS dataset level
operations and ZFS tries hard to ensure that any modifications
do reach stable storage. That means that the operations are done
synchronously and that, for example, disk caches are flushed.
Thus, the tests can be very slow on real hardware.
It is recommended to place the default temporary directory or
a temporary directory specified by, for instance, TMP environment
variable on a memory backed filesystem.
