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.

When upgrading from the distribution-provided zfs-initramfs package on
root-on-zfs Ubuntu and Debian the system may fail to boot: this change

Porting Notes:
* The CLI long option arguments for '-t' and '-m' don't parse on linux
* Switched from kmem_alloc to vmem_alloc in zcp_lua_alloc
* Lua implementation is built as its own module (zlua.ko)
* Lua headers consumed directly by zfs code moved to 'include/sys/lua/'
* There is no native setjmp/longjump available in stock Linux kernel.
  Brought over implementations from illumos and FreeBSD
* The get_temporary_prop() was adapted due to VFS platform differences
* Use of inline functions in lua parser to reduce stack usage per C call
* Skip some ZFS Test Suite ZCP tests on sparc64 to avoid stack overflow

48ac22d855 initramfs: Honor canmount=off
The initramfs script was not honoring canmount=off.  With this change,
it does.  If the administrator has asked that a filesystem not be
mounted, that should be honored.

As an exception, the initramfs script ignores canmount=off on the
rootfs.  The rootfs should not have canmount=off set either.  However,
mounting it anyway seems harmless because it is being asked for
explicitly.  The point of this exception is to avoid the risk of
breaking existing systems, just in case someone has canmount=off set on
their rootfs.

The initramfs still mounts filesystems with canmount=noauto.  This is
necessary because it is typical to set that on the rootfs so that it can
be cloned.  Without canmount=noauto, the clones' duplicate mountpoints
would conflict.

This is the remainder of the fix for:

bd2958dea0 initramfs: Honor mountpoint=none/legacy
For filesystems that are children of the rootfs, when mountpoint=none or
mountpoint=legacy, the initrafms script would assume a mountpoint based
on the dataset path.  Given that the rootfs should have mountpoint=/ and
mountpoint inheritance is is the default behavior of ZFS, this behavior
seems unnecessary.  In any event, it turns mountpoint=none into a no-op.
That removes this option from the administrator, and if someone uses it,
it does not work as expected.  Worse yet, if the mountpoint directory
does not exist (which is the typical case for mountpoint=none), the
mounting and thus the boot process will fail.  For the case of
mountpoint=legacy, the assumed mountpoint may not be the correct value
set in /etc/fstab.

This change makes the initramfs script not mount the filesystem in
either case.  For mountpoint=none, this means we are correctly honoring
the setting.  For mountpoint=legacy, there are two scenarios:  If
canmount=on, the filesystem will be mounted by the normal mechanisms
later in the boot process.  If canmount=noauto, the filesystem will not
be mounted at all, unless the administrator has done something special.
If they're not doing something special and they want it mounted by the
initramfs, they can simply not set mountpoint=legacy.

This is part of the fix for:

4fc411f7a3 initramfs: Set elevator=noop on the rpool's disks
ZFS already sets elevator=noop for wholedisk vdevs (for all pools), but
typical root-on-ZFS installations use partitions.  This sets
elevator=noop on the disks in the root pool.

Ubuntu 16.04 and 16.10 had this.  It was lost in 17.04 due to Debian
switching to this upstream initramfs script.

57732964d3 Init script fixes
* Fix regression - "OVERLAY_MOUNTS" should have been "DO_OVERLAY_MOUNTS".
* Fix update-rc.d commands in postinst.  Thanx to subzero79@GitHub.
* Fix make sure a filesystem exists before trying to mount in mount_fs()
* Fix local variable usage.
* Fix to read_mtab():
  * Strip control characters (space - \040) from /proc/mounts GLOBALY,
    not just first occurrence.
  * Don't replace unprintable characters ([/-. ]) for use in the variable
    name with underscore. No need, just remove them all together.
* Add check_boolean() to check if a user configure option is
  set ('yes', 'Yes', 'YES' or any combination there of) OR '1'.
  Anything else is considered 'unset'.
* Add a ZFS_POOL_IMPORT to the default config.
  * This is a semi colon separated list of pools to import ONLY.
  * This is intended for systems which have _a lot_ of pools (from
    a SAN for example) and it would be to many to put in the
    ZFS_POOL_EXCEPTIONS variable..
* Add a config option "ZPOOL_IMPORT_OPTS" for adding additional options
  to "zpool import".
* Add documentation and the chance of overriding the ZPOOL_CACHE
  variable in the config file.
* Remove "sort" from find_pools() and setup_snapshot_booting().
  Sometimes not available, and not really necessary.

* Include /lib/udev/vdev_id file in the initrd.
* Because the initrd needs to use '/sbin/modprobe' instead of 'modprobe',
  we need to use this in load_module() as well.
  * Make sure that load_module() can be used more globaly, instead of

2cac7f5f11 Initramfs scripts for ZoL.
* Supports booting of a ZFS snapshot.
  Do this by cloning the snapshot into a dataset. If this, the resulting
  dataset, already exists, destroy it. Then mount it on root.
  * If snapshot does not exist, use base dataset (the part before '@')
    as boot filesystem instead.
  * If no snapshot is specified on the 'root=' kernel command line, but there
    is an '@', then get a list of snapshots below that filesystem and ask the
    user which to use.
  * Clone with 'mountpoint=none' and 'canmount=noauto' - we mount manually
    and explicitly.
    * For sub-filesystems, that doesn't have a mountpoint property set, we use
      the 'org.zol:mountpoint' to keep track of it's mountpoint.
  * Allow rollback of snapshots instead of clone it and boot from the clone.
* Allow mounting a root- and subfs with mountpoint=legacy set
* Allow mounting a filesystem which is using nativ encryption.
* Support all currently used kernel command line arguments
  All the different distributions have their own standard on what to specify
  on the kernel command line to boot of a ZFS filesystem.
  * Extra options:
    * zfsdebug=(on,yes,1)	Show extra debugging information
    * zfsforce=(on,yes,1)	Force import the pool
    * rollback=(on,yes,1)	Rollback (instead of clone) the snapshot
* Only try to import pool if it haven't already been imported
  * This will negate the need to force import a pool that have not been exported cleanly.
  * Support exclusion of pools to import by setting ZFS_POOL_EXCEPTIONS in /etc/default/zfs.
* Support additional configuration variable ZFS_INITRD_ADDITIONAL_DATASETS
  to mount additional filesystems not located under your root dataset.
* Include /etc/modprobe.d/{zfs,spl}.conf in the initrd if it/they exist.
* Include the udev rule to use by-vdev for pool imports.
* Include the /etc/default/zfs file to the initrd.
* Only try /dev/disk/by-* in the initrd if USE_DISK_BY_ID is set.
  * Use /dev/disk/by-vdev before anything.
  * Add /dev as a last ditch attempt.
  * Fallback to using the cache file if that exist if nothing else worked.
* Use /sbin/modprobe instead of built-in (BusyBox) modprobe.
  This gets rid of the message "modprobe: can't load module zcommon".
  Thanx to pcoultha for finding this.
