Tony Hutter 0bc841fb59 zpool: Add slot power control, print power status
Add `zpool` flags to control the slot power to drives.  This assumes
your SAS or NVMe enclosure supports slot power control via sysfs.

The new `--power` flag is added to `zpool offline|online|clear`:

    zpool offline --power <pool> <device>    Turn off device slot power
    zpool online --power <pool> <device>     Turn on device slot power
    zpool clear --power <pool> [device]      Turn on device slot power

If the ZPOOL_AUTO_POWER_ON_SLOT env var is set, then the '--power'
option is automatically implied for `zpool online` and `zpool clear`
and does not need to be passed.

zpool status also gets a --power option to print the slot power status.

Tony Hutter dffe59c415 zed: misc vdev_enc_sysfs_path fixes
There have been rare cases where the VDEV_ENC_SYSFS_PATH value that zed
gets passed is stale.  To mitigate this, dynamically check the sysfs
path at the time of zed event processing, and use the dynamic value if
possible.  Note that there will be other times when we can not
dynamically detect the sysfs path (like if a disk disappears) and have
to rely on the old value for things like turning on the fault LED.  That
is to say, we can't just blindly use the dynamic path in every case.

Also:
	- Add enclosure sysfs entry when running 'zpool add'
	- Fix 'slot' and 'enc' zpool.d scripts for nvme

wasn't called.  To fix that move zfs_is_namespace_prop() inside the

Ameer Hamza 777c98ee52 Use setproctitle to report progress of zfs send
This allows parsing of zfs send progress by checking the process
title.
Doing so requires some changes to the send code in libzfs_sendrecv.c;
primarily these changes move some of the accounting around, to allow
for the code to be verbose as normal, or set the process title. Unlike
BSD, setproctitle() isn't standard in Linux; thus, borrowed it from
libbsd with slight modifications.

Ryan Moeller 1fdd768d7f libzfs: Fail making a dataset handle gracefully
When a dataset is in the process of being received it gets marked as
inconsistent and should not be used.  We should check for this when
opening a dataset handle in libzfs and return with an appropriate error
set, rather than hitting an abort because of the incomplete data.

zfs_open() passes errno to zfs_standard_error() after observing
make_dataset_handle() fail, which ends up aborting if errno is 0.
Set errno before returning where we know it has not been set already.
