Change ZEVENT_POOL_GUID to ZEVENT_POOL to display pool names
Outgoing mails for ZFS pool events include the pool GUID,
but not the actual pool name. Let's change this for better
readability, as it is already done in the mails for finished
pool resilvers.

Replace EXTRA_DIST with dist_noinst_DATA
The EXTRA_DIST variable is ignored when used in the FALSE conditional
of a Makefile.am.  This results in the `make dist` target omitting
these files from the generated tarball unless CONFIG_USER is defined.
This issue can be avoided by switching to use the dist_noinst_DATA
variable which is handled as expected by autoconf.

This change also adds support for --with-config=dist as an alias
for --with-config=srpm and updates the GitHub workflows to use it.

zed: support subject as header in zed_notify_email()
Some minimal MUAs don't support passing the subjects as cmdline option.
This commit checks if "@SUBJECT@" is missing in ZED_EMAIL_OPTS and then
prepends a subject header to the notification message.
Also set a default for ${subject}.

zed-functions.sh: escape newline to produce valid json
This was discovered when using Discords Slack compatible webhook.

Slack webhooks works without the escape, however Discord rightly refuses
the POST as it contains invalid JSON.

https://discord.com/developers/docs/resources/webhook#execute-slackcompatible-webhook

Valid (while escaping the newline:
```
+ msg_json='{"text": "*ZFS scrub_finish error for test on quartz*\nZFS has detected a data error:\n\n   eid: 124\n class: scrub_finish\n  host: quartz\n  time: \n error: \n objid: :\n  pool: test\n"}'
```

Invalid (no escape):
```
+ msg_json='{"text": "*ZFS scrub_finish error for test on quartz*
ZFS has detected a data error:\n\n   eid: 124\n class: scrub_finish\n  host: quartz\n  time: \n error: \n objid: :\n  pool: test\n"}'
```
The new line gets rendered and not sent inside the JSON as intended.

```
++ curl -X POST https://discord.com/api/webhooks/{webhook.id}/{webhook.token}/slack --header 'Content-Type: application/json' --data-binary '{"text": "*ZFS scrub_finish error for test on quartz*

zed syslog entries drop important info
ZED will log zevents summaries to the syslog, however the log entries 
tend to drop event details that can be useful for diagnosis. This is 
especially true for ereport events, like io, checksum, and delay.

Update the all-syslog.sh script to log additional event information.

Add an optional config option, ZED_SYSLOG_DISPLAY_GUIDS, to zed.rc
for choosing GUIDs over names for pool and vdev.

Change the default ZED_SYSLOG_SUBCLASS_EXCLUDE to exclude history_event 
events. These events tend to be frequent, convey no meaningful info, 
and are already logged in the zpool history.

Add device rebuild feature
The device_rebuild feature enables sequential reconstruction when
resilvering.  Mirror vdevs can be rebuilt in LBA order which may
more quickly restore redundancy depending on the pools average block
size, overall fragmentation and the performance characteristics
of the devices.  However, block checksums cannot be verified
as part of the rebuild thus a scrub is automatically started after
the sequential resilver completes.

The new '-s' option has been added to the `zpool attach` and
`zpool replace` command to request sequential reconstruction
instead of healing reconstruction when resilvering.

    zpool attach -s <pool> <existing vdev> <new vdev>
    zpool replace -s <pool> <old vdev> <new vdev>

The `zpool status` output has been updated to report the progress
of sequential resilvering in the same way as healing resilvering.
The one notable difference is that multiple sequential resilvers
may be in progress as long as they're operating on different
top-level vdevs.

The `zpool wait -t resilver` command was extended to wait on
sequential resilvers.  From this perspective they are no different
than healing resilvers.

Sequential resilvers cannot be supported for RAIDZ, but are
compatible with the dRAID feature being developed.

As part of this change the resilver_restart_* tests were moved
in to the functional/replacement directory.  Additionally, the
replacement tests were renamed and extended to verify both
resilvering and rebuilding.

Antonio Russo f88d069cbb systemd encryption key support
Modify zfs-mount-generator to produce a dependency on new
zfs-import-key-*.service units, dynamically created at boot to call
zfs load-key for the encryption root, before attempting to mount any
encrypted datasets.

These units are created by zfs-mount-generator, and RequiresMountsFor on
the keyfile, if present, or call systemd-ask-password if a passphrase is
requested.

This patch includes suggestions from @Fabian-Gruenbichler, @ryanjaeb and
@rlaager, as well an adaptation of @rlaager's script to retry on
incorrect password entry.

Antonio Russo 68fded8146 Add canonical mount options zfs-mount-generator
lib/libzfs/libzfs_mount.c:zfs_add_options provides the canonical
mount options used by a `zfs mount` command. Because we cannot call
`zfs mount` directly from a systemd.mount unit, we mirror that logic
in zfs-mount-generator.

The zed script is updated to cache these properties as well.

Include a mini-tutorial in the manual page, properly substitute
configuration paths in zfs-mount-generator.8.in, and standardize the
Makefile.

Antonio Russo 55d80e651a systemd mount generator and tracking ZEDLET
zfs-mount-generator implements the "systemd generator" protocol,
producing systemd.mount units from the cached outputs of zfs list,
during early boot, integrating with systemd.

Each pool has an indpendent cache of the command

  zfs list -H -oname,mountpoint,canmount -tfilesystem -r $pool

which is kept synchronized by the ZEDLET

  history_event-zfs-list-cacher.sh

Datasets not in the cache will be loaded later in the boot process by
zfs-mount.service, including pools without a cache.

Among other things, this allows for complex mount hierarchies.

Tony Hutter 639b18944a Allow to limit zed's syslog chattiness
Some usage patterns like send/recv of replication streams can
produce a large number of events. In such a case, the current
all-syslog.sh zedlet will hold up to its name, and flood the
logs with mostly redundant information. Two mitigate this
situation, this changeset introduces to new variables
ZED_SYSLOG_SUBCLASS_INCLUDE and ZED_SYSLOG_SUBCLASS_EXCLUDE
to zed.rc that give more control over which event classes end
up in the syslog.

Tony Hutter bf95a000c4 Add scrub after resilver zed script
* Add a zed script to kick off a scrub after a resilver.  The script is
disabled by default.

* Add a optional $PATH (-P) option to zed to allow it to use a custom
$PATH for its zedlets.  This is needed when you're running zed under
the ZTS in a local workspace.

* Update test scripts to not copy in all-debug.sh and all-syslog.sh by
default.  They can be optionally copied in as part of zed_setup().
These scripts slow down zed considerably under heavy events loads and
can cause events to be dropped or their delivery delayed. This was
causing some sporadic failures in the 'fault' tests.

Christopher Voltz 100790a8dd Retry setting LED
If the LED is being accessed by another process when we try to update
it, the update will be lost. Add a retry loop which will read the state
of the LED and update it until the LED is in the correct state. The
number of times this will occur is limited to ensure that the ZEDlet
won't hang ZED.

Refactor to remove duplication so setting of the LED occurs in only one
place.

Cleanup a couple of the warnings generated by shellcheck which weren't
the result of specific choices by the author. Several notes and warnings
are still present but removing them would make the code less clear or
require adding lines to tell shellcheck to ignore the warning.

Remove ",i" from the documentation at the top of the file which appears
to be a typographic error.

Tony Hutter 8720e9e748 Add -c to zpool iostat & status to run command
This patch adds a command (-c) option to zpool status and zpool iostat.  The
-c option allows you to run an arbitrary command on each vdev and display
the first line of output in zpool status/iostat.  The environment vars
VDEV_PATH and VDEV_UPATH are set to the vdev's path and "underlying path"
before running the command.  For device mapper, multipath, or partitioned
vdevs, VDEV_UPATH is the actual underlying /dev/sd* disk.  This can be useful
if the command you're running requires a /dev/sd* device.

The patch also uses /sys/block/<dev>/slaves/ to lookup the underlying device
instead of using libdevmapper.  This not only removes the libdevmapper
requirement at build time, but also allows you to resolve device mapper
devices without being root.  This means that UDEV_UPATH get set correctly
when running zpool status/iostat as an unprivileged user.

Example:

$ zpool status -c 'echo I am $VDEV_PATH, $VDEV_UPATH'

NAME        STATE     READ WRITE CKSUM
mypool      ONLINE       0     0     0
  mirror-0  ONLINE       0     0     0
    mpatha  ONLINE       0     0     0  I am /dev/mapper/mpatha, /dev/sdc
    sdb     ONLINE       0     0     0  I am /dev/sdb1, /dev/sdb
