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.

README

This package provides a wrapper for libzfs_core C library.

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.
