Porting Notes:
- Updated 'zpool labelclear' and 'zdb -l' such that they attempt
to find a vdev given solely its short name. This behavior is
consistent with the upstream OpenZFS code and the test cases
depend on it. The actual implementation differs slightly due
to device naming conventions on Linux.
- auto_online_001_pos, auto_replace_001_pos and add-o_ashift
test cases updated to expect failure when no label exists.
- read_efi_label() and zpool_label_disk_check() are read-only
operations and should use O_RDONLY at open time to enforce this.
- zpool_label_disk() and zpool_relabel_disk() write the partition
information using O_DIRECT an fsync() and page cache invalidation
to ensure a consistent view of the device.
- dump_label() in zdb should invalidate the page cache in order
to get the authoritative label from disk.

In the test an alias vdev_id rule is added for any scsi_debug

A symlink is created for the vdev_id.conf file (in /etc/zfs/ by

When a pool is suspended it's impossible to read the list
of damaged files from disk. This would result in a generic
misleading "insufficient permissions" error message.
Update zpool_get_errlog() to use the standard zpool error
logging functions to generate a useful error message. In
this case:
errors: List of errors unavailable: pool I/O is currently suspended
This patch does not address the related issue of potentially
not being able to resume a suspend pool when the underlying
device names have changed.
Additionally, remove the error handling from zfs_alloc()
in zpool_get_errlog() for readability since this function
can never fail.

For zdb -l, detect when the configuration nvlist in some label l (l>0)
is the same as a configuration already dumped. If so, do not dump it.
Make a similar check when dumping Uberblocks for zdb -lu. Check whether
a label already dumped contains an identical Uberblock. If so, do not
dump the Uberblock.
When dumping a configuration or Uberblock, state which labels it is
found in (0-3), for example: labels = 1 2 3
Detecting redundant uberblocks or configurations is accomplished by
calculating checksums of the uberblocks and the packed nvlists
containing the configuration.
If there is nothing unique to be dumped for a label (ie the
configuration and uberblocks have checksums matching those already
dumped) print nothing for that label.
With additional l's or u's, increase verbosity as follows:
-l Dump each unique configuration only once.
Indicate which labels it appears in.
-ll In addition, dump label space usage stats.
-lll Dump every configuration, unique or not.
-u Dump each unique, valid, uberblock only once.
Indicate which labels it appears in.
-uu In addition, state which slots are invalid.
-uuu Dump every uberblock, unique or not.
-uuuu Dump the uberblock blockpointer (used to be -uuu)
Make exit values conform to the manual page. Failing to unpack a
configuration nvlist is considered an error, as well as failing to open
or read from the device.
Add three tests, zdb_00{3,4,5}_pos to verify the above functionality.

Closes#5589
There are two cases:
1. if an invalid flag is passed, and
2. if a valid flag is not given a parameter.
In the case of (1), the flag is either short or long. For short flags,
optopt contains the character of the flag. For long, it contains zero,
and we can access the long flag using argv and optind.
In the case of (2), if the flag is short, optopt contains the character
of the flag. If the flag is long, the value in the 4th column of the
long_options table, for that flag, is returned.
We could case over all those values, or we could simply use argv and
optind again.
Note that in the case of something like `--resume`, which is also `-t`,
"t" will be returned if an argument is not provided; so the error
message will say `'t': argument not provided` or similar. This could be
fixed by making it so long and short options don't use the same
character flag, and then combining them in the switch/case statement,
but I didn't think the ugliness of the code would be worth the small
usability enhancement.

zpool iostat allows you to specify only certain vdevs to display.
Currently, if you run 'zpool iostat -c CMD vdev1 vdev2 ...'
on specific vdevs, it will actually run the command on *all* vdevs,
and just display the results for the vdevs you specify. This patch
corrects the behavior to only run the command on the specified vdevs,
and also enables the zpool_iostat_005_pos.ksh tests.
