Only down to tests/zfs-tests/tests, but pull out C programs into the
main Makefile ‒ this means we get correct dependency tracking for all
programs (and parallelise across them)

Closes#13316
Tests that get killed do not have an opportunity to clean up.
There are many bad states this can leave the system in, but of
particular gravity is when zinject has been used to induce bad
behavior for one or more of the test disks.
Create a failsafe mechanism in test-runner.py that runs a callback
script after every test. The script is common to all tests so all
tests benefit from the protection.
Add an obligatory `zinject -c all` to clear all zinject state after
every test case is run.

It's better to use ksh/bash built in methods,
rather than spawn new processes every time.

Closes#8071
Add multihost=on|off pool property to control MMP. When enabled
a new thread writes uberblocks to the last slot in each label, at a
set frequency, to indicate to other hosts the pool is actively imported.
These uberblocks are the last synced uberblock with an updated
timestamp. Property defaults to off.
During tryimport, find the "best" uberblock (newest txg and timestamp)
repeatedly, checking for change in the found uberblock. Include the
results of the activity test in the config returned by tryimport.
These results are reported to user in "zpool import".
Allow the user to control the period between MMP writes, and the
duration of the activity test on import, via a new module parameter
zfs_multihost_interval. The period is specified in milliseconds. The
activity test duration is calculated from this value, and from the
mmp_delay in the "best" uberblock found initially.
Add a kstat interface to export statistics about Multiple Modifier
Protection (MMP) updates. Include the last synced txg number, the
timestamp, the delay since the last MMP update, the VDEV GUID, the VDEV
label that received the last MMP update, and the VDEV path. Abbreviated
output below.

Add a new tunable zfs_multihost_history to specify the number of MMP
updates to store history for. By default it is set to zero meaning that
no MMP statistics are stored.
When using ztest to generate activity, for automated tests of the MMP
function, some test functions interfere with the test. For example, the
pool is exported to run zdb and then imported again. Add a new ztest
function, "-M", to alter ztest behavior to prevent this.
Add new tests to verify the new functionality. Tests provided by
Giuseppe Di Natale.
