Enable remaining tests

Enable most of the remaining test cases which were previously
disabled.  The required fixes are as follows:

* cache_001_pos - No changes required.

* cache_010_neg - Updated to use losetup under Linux.  Loopback
  cache devices are allowed, ZVOLs as cache devices are not.
  Disabled until all the builders pass reliably.

* cachefile_001_pos, cachefile_002_pos, cachefile_003_pos,
  cachefile_004_pos - Set set_device_dir path in cachefile.cfg,
  updated CPATH1 and CPATH2 to reference unique files.

* zfs_clone_005_pos - Wait for udev to create volumes.

* zfs_mount_007_pos - Updated mount options to expected Linux names.

* zfs_mount_009_neg, zfs_mount_all_001_pos - No changes required.

* zfs_unmount_005_pos, zfs_unmount_009_pos, zfs_unmount_all_001_pos -
  Updated to expect -f to not unmount busy mount points under Linux.

* rsend_019_pos - Observed to occasionally take a long time on both
  32-bit systems and the kmemleak builder.

* zfs_written_property_001_pos - Switched sync(1) to sync_pool.

* devices_001_pos, devices_002_neg - Updated create_dev_file() helper
  for Linux.

* exec_002_neg.ksh - Fixed mmap_exec.c to preserve errno.  Updated
  test case to expect EPERM from Linux as described by mmap(2).

* grow_pool_001_pos - Adding missing setup.ksh and cleanup.ksh
  scripts from OpenZFS.

* grow_replicas_001_pos.ksh - Added missing $SLICE_* variables.

* history_004_pos, history_006_neg, history_008_pos - Fixed by
  previous commits and were not enabled.  No changes required.

* zfs_allow_010_pos - Added missing spaces after assorted zfs
  commands in delegate_common.kshlib.

* inuse_* - Illumos dump device tests skipped.  Remaining test
  cases updated to correctly create required partitions.

* large_files_001_pos - Fixed largest_file.c to accept EINVAL
  as well as EFBIG as described in write(2).

* link_count_001 - Added nproc to required commands.

* umountall_001 - Updated to use umount -a.

* online_offline_001_* - Pull in OpenZFS change to file_trunc.c
  to make the '-c 0' option run the test in a loop.  Included
  online_offline.cfg file in all test cases.

* rename_dirs_001_pos - Updated to use the rename_dir test binary,
  pkill restricted to exact matches and total runtime reduced.

* slog_013_neg, write_dirs_002_pos - No changes required.

* slog_013_pos.ksh - Updated to use losetup under Linux.

* slog_014_pos.ksh - ZED will not be running, manually degrade
  the damaged vdev as expected.

* nopwrite_varying_compression, nopwrite_volume - Forced pool
  sync with sync_pool to ensure up to date property values.

* Fixed typos in ZED log messages.  Refactored zed_* helper
  functions to resolve all-syslog exit=1 errors in zedlog.

* zfs_copies_005_neg, zfs_get_004_pos, zpool_add_004_pos,
  zpool_destroy_001_pos, largest_pool_001_pos, clone_001_pos.ksh,
  clone_001_pos, - Skip until layering pools on zvols is solid.

* largest_pool_001_pos - Limited to 7eb pool, maximum
  supported size in 8eb-1 on Linux.

* zpool_expand_001_pos, zpool_expand_003_neg - Requires
  additional support from the ZED, updated skip reason.

* zfs_rollback_001_pos, zfs_rollback_002_pos - Properly cleanup
  busy mount points under Linux between test loops.

* privilege_001_pos, privilege_003_pos, rollback_003_pos,
  threadsappend_001_pos - Skip with log_unsupported.

* snapshot_016_pos - No changes required.

* snapshot_008_pos - Increased LIMIT from 512K to 2M and added
  sync_pool to avoid false positives.
