Implement a new type of zfs receive: corrective receive (-c)
This type of recv is used to heal corrupted data when a replica
of the data already exists (in the form of a send file for example).
With the provided send stream, corrective receive will read from
disk blocks described by the WRITE records. When any of the reads
come back with ECKSUM we use the data from the corresponding WRITE
record to rewrite the corrupted block.

Matthew Ahrens 59ec30a329 Remove code for zfs remap
The "zfs remap" command was disabled by
6e91a72fe3, because it has little utility
and introduced some tricky bugs.  This commit removes the code for it,
the associated ZFS_IOC_REMAP ioctl, and tests.

Note that the ioctl and property will remain, but have no functionality.
This allows older software to fail gracefully if it attempts to use
these, and avoids a backwards incompatibility that would be introduced if
we renumbered the later ioctls/props.

Antonio Russo 9de8c0cd7f pyzfs: python3 support (library 1/2)
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
* relative import fixes

Andriy Gapon dc1c630b8a OpenZFS 9630 - add lzc_rename and lzc_destroy to libzfs_core
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()

Tom Caputi d9c460a0b6 Added encryption support for zfs recv -o / -x
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.

loli10K 85ce3f4fd1 Adopt pyzfs from ClusterHQ
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.

Andriy Gapon 6abf922574 Import pyzfs source code from ClusterHQ
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.
