Closes#7793Closes#7800
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.
