When _zed_event_add_var() was updated to be the common routine
for adding zedlet environment variables, an additional snprintf()
was added to the processing of each nvpair. This commit changes
_zed_event_add_nvpair() to directly call _zed_event_add_var()
for nvpair non-array types, thereby removing a superfluous call to
snprintf(). For consistency, the helper functions for converting
nvpair array types are similarly adjusted to add variables.
The _zed_event_value_is_hex() and _zed_event_add_var() functions have
been moved up in the file since forward declarations are not used,
but no changes have been made to these functions.

The zed_strings container stores strings in an AVL, but does not
check for duplicate strings being added. Within the AVL, strings
are indexed by the string value itself. avl_add() requires the node
being added must not already exist in the tree, and will assert()
if this is not the case.
This should not cause problems in practice. ZED uses this container
in two places. In zed_conf.c, it is used to store the names of
enabled zedlets as zed scans the zedlet directory listing; duplicate
entries cannot occur here since duplicate names cannot occur within
a directory. In zed_event.c, it is used to store the environment
variables (as "NAME=VALUE" strings) that will be passed to zedlets;
duplicate strings here should never happen unless there is a bug
resulting in a duplicate nvpair or environment variable.
This commit protects against adding a duplicate to a zed_strings
container by first checking for the string being added, and removing
the previous entry should one exist. This implements a "last one
wins" policy.
This commit also changes the prototype for zed_strings_add() to allow
the string key (by which it is indexed in the AVL) to differ from
the string value. By adding zedlet environment variables using the
variable name as the key, multiple adds for the same variable name
will result in only the last value being stored.
Finally, this commit routes all additions of zedlet environment
variables through the updated _zed_event_add_var(). This ensures
all zedlet environment variable names are properly converted.

The -p option is used to specify a specific page of output to be
displayed. If omitted, all output pages would be displayed.
arc_summary, as it stood, had really kludgy processing code for
processing the -p option. It relied on a try-except block which was
treated as an if statement and in normal operation would fail any time a
user didn't specify the -p option on the command line. When the
exception was thrown, the script would then display all output pages.
This happened whether the -p option was omitted or malformed. Thus, in
the principle use case, an exception would be raised in order to run the
script as desired. The same except code would be called regardless of
the exception, however, and malformed -p arguments would also cause the
script to execute.
Additionally, this required the function which handles the case where
all output pages were to be displayed, _call_all, to be potentially
called from several locations within main.
This commit refactors the option processing code to simplify it and make
it easier to catch runtime errors in the script. This is done by
specializing the try-except block to only have an exception when the -p
argument is malformed. When the -p option is correctly selected by the
user, it calls a function in the unSub array directly, which will only
display one page of output.
Finally in the context of this refactoring the page breaks have been
removed. Pages seem to have been added into the output in the FreeNAS
version of the script. This patch removes pages from the output to more
closely resemble the freebsd version of the script.

The arc_summary script is a useful utility for administrators on
other ZFS platforms. It provides a quick and easy way to get a high
level view of the current ARC state.
Historically this was a perl script but it was rewritten in python
for FreeNAS. We've decided to adopt the python version instead of
the perl version for a few reasons.
1) ZoL has no existing perl dependencies, but it does have a python
dependency for scripts such as arcstat.py and dbufstat.py. Using
python for arc_summary.py helps us minimize dependencies.
2) Most major Linux distributions already depend heavily on python
for their core infrastructure. This means it's very likely to
be available even very early in the boot process.

Slot mapping in vdev_id doesn't work on systems using mawk as the 'awk'
alternative. A regular expression in map_slot() contains an unquoted
empty string following the alternation (|) operator, which results in an
"missing operand" error with mawk. The solution is to rearrange the
expression so the alternation has two operands.

ZED uses an advisory lock on its state file to protect against
multiple instances running concurrently. However, work is planned
to move this state information into the kernel, and ZED will still
need to protect against starting multiple instances.
This commit adds an advisory lock on the PID file to protect against
starting multiple instances. A lock failure can be overridden with
the "-f" (force) command-line option. The advisory lock on the state
file is being retained for as long as the state information is stored
in the state file.

Creating virtual machines that have their rootfs on ZFS on hosts that
have their rootfs on ZFS causes SPA namespace collisions when the
standard name rpool is used. The solution is either to give each guest
pool a name unique to the host, which is not always desireable, or boot
a VM environment containing an ISO image to install it, which is
cumbersome.
26b42f3f9d03f85cc7966dc2fe4dfe9216601b0e introduced `zpool import -t
...` to simplify situations where a host must access a guest's pool when
there is a SPA namespace conflict. We build upon that to introduce
`zpool import -t tname ...`. That allows us to create a pool whose
in-core name is tname, but whose on-disk name is the normal name
specified.
This simplifies the creation of machine images that use a rootfs on ZFS.
That benefits not only real world deployments, but also ZFSOnLinux
development by decreasing the time needed to perform rootfs on ZFS
experiments.

zpool import's -t parameter is intended for use with -R when operating
on pools that belong to other systems. Like -R, pools imported in this
way should not update the cachefile unless explicitly requested. The
initial implementation allowed the cachefile to be updated when -R was
not used. This went uncaught during testing because -R had implicitly
disabled use of the cachefile.

This is a set of minor cleanup changes related to zed logging:
- Remove the program identity prefix from messages written to stderr
since systemd already prepends this output with the program name.
- Replace the copy of the program identity string with a ptr reference.
- Replace "pid" with "PID" for consistency in comments & strings.
- Rename the zed_log.c struct _ctx component "level" to "priority".
- Add the LOG_PID option for messages written to syslog.

When the zed is started as a forking daemon (by default),
a race-condition exists where the parent process can terminate before
the pidfile has been created by the grandchild process. When invoked
as a Type=forking systemd service, this can result in the following:
systemd[1]: Starting ZFS Event Daemon (zed)...
systemd[1]: PID file /var/run/zed.pid not readable (yet?) after start.
This commit adds a daemonize pipe to allow the grandchild process to
signal the parent process that initialization is complete (and the
pidfile has been created). The parent process will wait for this
notification before exiting.

4970 need controls on i/o issued by zpool import -XF
4971 zpool import -T should accept hex values
4972 zpool import -T implies extreme rewind, and thus a scrub
4973 spa_load_retry retries the same txg
4974 spa_load_verify() reads all data twice

Notes:
This set of patches adds a set of tunable parameters for the
"extreme rewind" mode of pool import which allows control over
the traversal performed during such an import.

The Intel DC S3500 and Intel DC S3700 are optimized to handle 4KB
sectors well despite of their 8KB page sizes, so we move them to a new
category for enterprise drives where they will receive ashift=12. They
are joined by the Intel 730 series, which uses the same disk controller,
as well as a San Disk enterprise drive. The drive IDs for these two were
obtained by myself with the drive_id utility. The drive ID for the 240GB
Intel 730 model was extrapolated from the drive ID for the 480GB model.
Lastly, we also add some Western Digital mobile drives. ryuo in
\#zfsonlinux on freenode obtained "ATA WDC WD2500BEVT-0" from
running drive_id on his own hardware. The additional drives in that
family were extrapolated from that identifer.

Notes:
The "zdb -M" option has been re-tasked to display the new metaslab
fragmentation metric and the new "zdb -I" option is used to control
the maximum number of in-flight I/Os.
The new fragmentation metric is derived from the space map histogram
which has been rolled up to the vdev and pool level and is presented
to the user via "zpool list".
Add a number of module parameters related to the new metaslab weighting
logic.

Add a new 'overlay' property (default 'off') that controls whether the
filesystem should be mounted even if the mountpoint is busy or if it
should fail with a 'mountpoint not empty'.
Doing overlay mounts is the default mount behavior on Linux, but not
in ZFS. It have been decided that following the ZFS behavior should
be the default, but this overlay allows for site administrator to
override this decision on a per-dataset basis.

Porting notes:
For compatibility with the fastpath code the zio_done() function
needed to be updated. Because embedded-data block pointers do
not require DVAs to be allocated the associated vdevs will not
be marked and therefore should not be unmarked.
