When cleaning up a test case standardize on using the convention:
datasetexists $ds && destroy_dataset $ds <flags>
By using 'destroy_dataset' instead of 'log_must zfs destroy' we ensure
that the destroy is retried in the event that a ZFS volume is busy.
This helps ensures ensure tests are fully cleaned up and prevents false
positive test failures on Linux.
Note that all of the tests which used 'zfs destroy' in cleanup have
been updated even if they don't use volumes. This was done to
clearly establish the expected convention.

If there is no scsi_debug module, then this test
must be skipped, in this case cleanup routine should
be prepared for absent pool.

The externally faulted vdev should be brought back online and have
its errors cleared before the pool is destroyed. Failure to do so
will leave a vdev with a valid active label. This vdev may then
not be used to create a new pool without the -f flag potentially
leading to subsequent test failures.
Additionally remove an unreachable log_pass from setup.ksh.

* devices_001_pos and devices_002_neg - Failing after FreeBSD ZTS
merged due to missing 'function' keyword for create_dev_file_linux.
* pool_state - Occasionally fails due to an insufficient delay
before checking 'zpool status'. Increasing the delay from 1 to 3
seconds resolved the issue in local testing.
* procfs_list_basic - Fails when run in-tree because the logged
command is actually 'lt-zfs'. Updated the regex accordingly.

Update the common ZTS scripts and individual test cases as needed
in order to allow them to be run on FreeBSD. The high level goal
is to provide compatibility wrappers whenever possible to minimize
changes to individual test cases.

It's better to use ksh/bash built in methods,

There are some issues with the way the seq_file interface is implemented
for kstats backed by linked lists (zfs_dbgmsgs and certain per-pool
debugging info):
* We don't account for the fact that seq_file sometimes visits a node
multiple times, which results in missing messages when read through
procfs.
* We don't keep separate state for each reader of a file, so concurrent
readers will receive incorrect results.
* We don't account for the fact that entries may have been removed from
the list between read syscalls, so reading from these files in procfs
can cause the system to crash.
This change fixes these issues and adds procfs_list, a wrapper around a
linked list which abstracts away the details of implementing the
seq_file interface for a list and exposing the contents of the list
through procfs.
