ZTS: normalize on use of sync_pool and sync_all_pools
- Replaces use of manual `zpool sync`
- Don't use `log_must sync_pool` as `sync_pool` uses it internally
- Replace many (but not all) uses of `sync` with `sync_pool`

This makes the tests more consistent, and makes searching easier.

Distributed Spare (dRAID) Feature
This patch adds a new top-level vdev type called dRAID, which stands
for Distributed parity RAID.  This pool configuration allows all dRAID
vdevs to participate when rebuilding to a distributed hot spare device.
This can substantially reduce the total time required to restore full
parity to pool with a failed device.

A dRAID pool can be created using the new top-level `draid` type.
Like `raidz`, the desired redundancy is specified after the type:
`draid[1,2,3]`.  No additional information is required to create the
pool and reasonable default values will be chosen based on the number
of child vdevs in the dRAID vdev.

    zpool create <pool> draid[1,2,3] <vdevs...>

Unlike raidz, additional optional dRAID configuration values can be
provided as part of the draid type as colon separated values. This
allows administrators to fully specify a layout for either performance
or capacity reasons.  The supported options include:

    zpool create <pool> \
        draid[<parity>][:<data>d][:<children>c][:<spares>s] \
        <vdevs...>

    - draid[parity]       - Parity level (default 1)
    - draid[:<data>d]     - Data devices per group (default 8)
    - draid[:<children>c] - Expected number of child vdevs
    - draid[:<spares>s]   - Distributed hot spares (default 0)

Abbreviated example `zpool status` output for a 68 disk dRAID pool
with two distributed spares using special allocation classes.

When adding test coverage for the new dRAID vdev type the following
options were added to the ztest command.  These options are leverages
by zloop.sh to test a wide range of dRAID configurations.

    -K draid|raidz|random - kind of RAID to test
    -D <value>            - dRAID data drives per group
    -S <value>            - dRAID distributed hot spares
    -R <value>            - RAID parity (raidz or dRAID)

The zpool_create, zpool_import, redundancy, replacement and fault
test groups have all been updated provide test coverage for the
dRAID feature.

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.

ZTS: Test case reliability
* Both cli_root/zpool_import/import_cache_device_replaced, and
  redundancy/redundancy_004_neg have been observed to fail for
  spurious reasons ~1% of the time.  Add them to the exception
  list and reference the open Github issue.

* Speed up replacement/replacement_001_pos to prevent it from
  exceeding the 10 minute per test limit and getting KILLED.
  File vdev creation switched to truncate -s, redundant raidz1
  testing pass dropped, fixed some minor formating issues.

6c9af9e8f4 Fix "file is executable, but no shebang" warnings
Fedora 28's RPM build checks warn when executable files don't have a
shebang line.  These warnings are caused when we (incorrectly)
include data & config files in the_SCRIPTS automake lines. Files in
_SCRIPTS are marked executable by automake. This patch fixes the
issue by including non-executable scripts in a _DATA line instead.

Porting Notes:
- Utilities which aren't available under Linux have been removed.
- Because of sudo's default secure path behavior PATH must be
  explicitly reset at the top of libtest.shlib.  This avoids the
  need for all users to customize secure path on their system.
- Updated ZoL infrastructure to manage constrained path
- Updated all test cases
- Check permissions for usergroup tests
- When testing in-tree create links under bin/
- Update fault cleanup such that missing files during
  cleanup aren't fatal.
- Configure su environment with constrained path

edd770ebfb remove sanity check in replacement test
In replacement test, it spawns a process to truncate a file background
and make sure that the process exists 1 second later. However, the
process may have finished its work and exited therefore it has the
chance to report a false alarm.

This patch just removed those sanity check.

6bb24f4dc7 Add the ZFS Test Suite
Add the ZFS Test Suite and test-runner framework from illumos.
This is a continuation of the work done by Turbo Fredriksson to
port the ZFS Test Suite to Linux.  While this work was originally
conceived as a stand alone project integrating it directly with
the ZoL source tree has several advantages:

  * Allows the ZFS Test Suite to be packaged in zfs-test package.
    * Facilitates easy integration with the CI testing.
    * Users can locally run the ZFS Test Suite to validate ZFS.
      This testing should ONLY be done on a dedicated test system
      because the ZFS Test Suite in its current form is destructive.
  * Allows the ZFS Test Suite to be run directly in the ZoL source
    tree enabled developers to iterate quickly during development.
  * Developers can easily add/modify tests in the framework as
    features are added or functionality is changed.  The tests
    will then always be in sync with the implementation.

Full documentation for how to run the ZFS Test Suite is available
in the tests/README.md file.

Warning: This test suite is designed to be run on a dedicated test
system.  It will make modifications to the system including, but
not limited to, the following.

  * Adding new users
  * Adding new groups
  * Modifying the following /proc files:
    * /proc/sys/kernel/core_pattern
    * /proc/sys/kernel/core_uses_pid
  * Creating directories under /

Notes:
  * Not all of the test cases are expected to pass and by default
    these test cases are disabled.  The failures are primarily due
    to assumption made for illumos which are invalid under Linux.
  * When updating these test cases it should be done in as generic
    a way as possible so the patch can be submitted back upstream.
    Most existing library functions have been updated to be Linux
    aware, and the following functions and variables have been added.
    * Functions:
      * is_linux          - Used to wrap a Linux specific section.
      * block_device_wait - Waits for block devices to be added to /dev/.
    * Variables:            Linux          Illumos
      * ZVOL_DEVDIR         "/dev/zvol"    "/dev/zvol/dsk"
      * ZVOL_RDEVDIR        "/dev/zvol"    "/dev/zvol/rdsk"
      * DEV_DSKDIR          "/dev"         "/dev/dsk"
      * DEV_RDSKDIR         "/dev"         "/dev/rdsk"
      * NEWFS_DEFAULT_FS    "ext2"         "ufs"
  * Many of the disabled test cases fail because 'zfs/zpool destroy'
    returns EBUSY.  This is largely causes by the asynchronous nature
    of device handling on Linux and is expected, the impacted test
    cases will need to be updated to handle this.
  * There are several test cases which have been disabled because
    they can trigger a deadlock.  A primary example of this is to
    recursively create zpools within zpools.  These tests have been
    disabled until the root issue can be addressed.
  * Illumos specific utilities such as (mkfile) should be added to
    the tests/zfs-tests/cmd/ directory.  Custom programs required by
    the test scripts can also be added here.
  * SELinux should be either is permissive mode or disabled when
    running the tests.  The test cases should be updated to conform
    to a standard policy.
  * Redundant test functionality has been removed (zfault.sh).
  * Existing test scripts (zconfig.sh) should be migrated to use
    the framework for consistency and ease of testing.
  * The DISKS environment variable currently only supports loopback
    devices because of how the ZFS Test Suite expects partitions to
    be named (p1, p2, etc).  Support must be added to generate the
    correct partition name based on the device location and name.
  * The ZFS Test Suite is part of the illumos code base at:
    https://github.com/illumos/illumos-gate/tree/master/usr/src/test
