This commit add a new feature for Debian-based distributions to unlock
encrypted root partition over SSH. This feature is very handy on
headless NAS or VPS cloud servers. To use this feature, you will need
to install the dropbear-initramfs package.

The initramfs hook scripts depend on Makefile. This way, if the
substitution code is changed, they should update. This brings it in
line with etc/init.d (which was modified to match the example in the
automake docs).
The initramfs hook script cleaning now matches etc/init.d.
There was a mix of SUBDIRS recursion and custom install rules for files
in subdirectories. This was duplicated for the "hooks" and "scripts"
subdirectories. Now everything uses SUBDIRS.
I fixed the substitution of DEFAULT_INITCONF_DIR for hooks/zfs.

This fixes a bug where the generated zfs-functions was being included
along with original zfs-functions.in in the make dist tarball. This
caused an unfortunate series of events during build/packaging that
resulted in the RPM-installed /etc/zfs/zfs-functions listing the
paths as:
ZFS="/usr/local/sbin/zfs"
ZED="/usr/local/sbin/zed"
ZPOOL="/usr/local/sbin/zpool"
When they should have been:
ZFS="/sbin/zfs"
ZED="/sbin/zed"
ZPOOL="/sbin/zpool"
This affects init.d (non-systemd) distros like CentOS 6.
/etc/default/zfs and /etc/zfs/zfs-functions are also used by the
initramfs, so they need to be built even when init.d support is not.
They have been moved to the (new) etc/default and (existing) etc/zfs
source directories, respectively.
Fixes: #9443

* contrib/initramfs: include /etc/default/zfs and /etc/zfs/zfs-functions
At least debian needs /etc/default/zfs and /etc/zfs/zfs-functions for
its initramfs. Include both in build when initramfs is configured.
* contrib/initramfs: include 60-zvol.rules and zvol_id
Include 60-zvol.rules and zvol_id and set udev as predependency instead
of debians zdev. This makes debians additional zdev hook unneeded.
* Correct initconfdir substitution for some distros
Not every Linux distro is using @sysconfdir@/default but @initconfdir@
which is already determined by configure. Let's use it.
* systemd: prevent possible conflict between systemd and sysvinit
Systemd will not load a sysvinit service if a unit exists with the same
name. This prevents conflicts between sysvinit and systemd.
In ZFS there is one sysvinit service that does not have a systemd
service but a target counterpart, zfs-import.target.
Usually it does not make any sense to install both but it is possisble.
Let's prevent any conflict by masking zfs-import.service by default.
This does not harm even if init.d/zfs-import does not exist.

* rpm: correct pkgconfig path
pkconfig files get installed to $datarootdir/pkgconfig but rpm expects
them to be at $datadir. This works when $datarootdir==$datadir which is
the case most of the time but will fail when they differ.
* install: make initramfs-tools path static
Since initramfs-tools' path is nothing we can control as it is an
external package it does not make any sense to install zfs additions
anywhere else. Simply use /usr/share/initramfs-tools as path.

Resolve the incorrect use of srcdir and builddir references for
various files in the build system. These have crept in over time
and went unnoticed because when building in the top level directory
srcdir and builddir are identical.
With this change it's again possible to build in a subdirectory.

$ cd obj
$ ../configure
$ make

* 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".
