Fix inconsistent mount options for ZFS root
While mounting ZFS root during boot on Linux distributions from initrd,
mount from busybox is effectively used which executes mount system call
directly. This skips the ZFS helper mount.zfs, which checks and enables
the mount options as specified in dataset properties. As a result,
datasets mounted during boot from initrd do not have correct mount
options as specified in ZFS dataset properties.

There has been an attempt to use mount.zfs in zfs initrd script,
responsible for mounting the ZFS root filesystem (PR#13305). This was
later reverted (PR#14908) after discovering that using mount.zfs breaks
mounting of snapshots on root (/) and other child datasets of root have
the same issue (Issue#9461).

This happens because switching from busybox mount to mount.zfs correctly
parses the mount options but also adds 'mntpoint=/root' to the mount
options, which is then prepended to the snapshot mountpoint in
'.zfs/snapshot'. '/root' is the directory on Debian with initramfs-tools
where root filesystem is mounted before pivot_root. When Linux runtime
is reached, trying to access the snapshots on root results in
automounting the snapshot on '/root/.zfs/*', which fails.

This commit attempts to fix the automounting of snapshots on root, while
using mount.zfs in initrd script. Since the mountpoint of dataset is
stored in vfs_mntpoint field, we can check if current mountpoint of
dataset and vfs_mntpoint are same or not. If they are not same, reset
the vfs_mntpoint field with current mountpoint. This fixes the
mountpoints of root dataset and children in respective vfs_mntpoint
fields when we try to access the snapshots of root dataset or its
children. With correct mountpoint for root dataset and children stored
in vfs_mntpoint, all snapshots of root dataset are mounted correctly
and become accessible.

This fix will come into play only if current process, that is trying to
access the snapshots is not in chroot context. The Linux kernel API
that is used to convert struct path into char format (d_path), returns
the complete path for given struct path. It works in chroot environment
as well and returns the correct path from original filesystem root.

However d_path fails to return the complete path if any directory from
original root filesystem is mounted using --bind flag or --rbind flag
in chroot environment. In this case, if we try to access the snapshot
from outside the chroot environment, d_path returns the path correctly,
i.e. it returns the correct path to the directory that is mounted with
--bind flag. However inside the chroot environment, it only returns the
path inside chroot.

For now, there is not a better way in my understanding that gives the
complete path in char format and handles the case where directories from
root filesystem are mounted with --bind or --rbind on another path which
user will later chroot into. So this fix gets enabled if current
process trying to access the snapshot is not in chroot context.

With the snapshots issue fixed for root filesystem, using mount.zfs in
ZFS initrd script, mounts the datasets with correct mount options.

initramfs: fix zpool get argument order
When using the zfs initramfs scripts on my system, I get various
errors at initramfs stage, such as:

cannot open '-o': name must begin with a letter

My zfs binaries are compiled with musl libc, which may be why
this happens. In any case, fix the argument order to make the
zpool binary happy, and to match its --help output.

rootdelay on zfs should be adaptive
The 'rootdelay' boot option currently pauses the boot for a specified
amount of time. The original intent was to ensure that slower
configurations would have ample time to enumerate the devices to make
importing the root pool successful. This, however, causes unnecessary
boot delay for environments like Azure which set this parameter by
default.

This commit changes the initramfs logic to pause until it can
successfully load the 'zfs' module. The timeout specified by
'rootdelay' now becomes the maximum amount of time that initramfs will
wait before failing the boot.

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.

initramfs: use mount.zfs instead of mount
A followup to d7a67402a8

For `mount -t zfs -o opts ds mp` command line
some implementations of `mount(8)`, e. g. Busybox in Debian
work as follows:

```
newfstatat(AT_FDCWD, "ds", 0x7fff826f4ab0, 0) = -1
mount("ds", "mp", "zfs", MS_SILENT, NULL) = 0
```

The logic above skips completely `mount.zfs` and prevents us
from reading filesystem properties and applying mount options.

For comparison, the coreutils `mount(8)` implementation does:

```
openat(AT_FDCWD, "/proc/filesystems", O_RDONLY|O_CLOEXEC) = 3
// figure out that zfs is a `nodev` filesystem and look for a helper
newfstatat(AT_FDCWD, "/sbin/mount.zfs" ...) = 0
execve("/sbin/mount.zfs" ...) = 0
```

Using `mount.zfs` in initramfs would help circumvent deficiencies
of some of `mount(8)` implementations. `mount -t zfs` translates
to `mount.zfs` invocation, except for cases when explicitly disabled
by `-i`.

Remove zdb and libzpool from initramfs image
= Motivation

At Delphix we are heavy users of kernel crash dumps that are captured
through a crash kernel that is spawned whenever the main kernel panics.
The way that this works internally is that a certain amount of memory is
reserved while the main system is running so the initramfs of the crash
kernel can be loaded when a panic occurs.

In order to keep reserved memory at minimum we've been historically
trying to identify the binaries that are part of the kernel's initramfs
that are big and finding ways of either making them smaller or do not
include them in the initramfs image. An example is always stripping the
DWARF info of the ZFS kernel module copy that is included in the
initramfs image of both our running and our crash kernel (the difference
in size there is 76MB vs 4MB).

We've recently identified that libzpool has been the largest binary in
our initramfs images - currently sized around 17MB.

= This Patch

The ZFS scripts do not explicitly copy libzpool to initramfs. They copy
zdb which pulls in libzpool as a dependency. Given that both zdb and
libzpool are not really essential for initramfs (e.g. we'll still have
access to the once the root filesystem is unpacked) this patch removes
them from initramfs.

aa5a4eb5d0 i-t: don't brokenly set the scheduler for root pool vdev's disks
This effectively reverts
  4fc411f7a3 (part of #6807) and
  f6fbe25664 (#9042) ‒
the code itself and latter PR cite symmetry with whole-disk-vdev
behaviour (presumably because rootfs vdevs are rarely whole disks),
but the code is broken for NVME devices (indeed, it'd strip the
controller number instead of the (potential) partition number, turning
"nvme0n1p1" into "nvmen1p1", which would then subsequently fail the
sysfs existence check); it could be fixed to handle those (and any
others) rather easily by dereferencing /sys/class/block/$devname,
but this isn't the place for setting this ‒ as noted in the commit that
removed setting the scheduler by default
(9e17e6f254) ‒ use an udev rule

Silence 'make checkbashisms'
Commit d2bce6d03 added the 'make checkbashisms' target but did not
resolve all of the bashisms in the scripts.  This commit doesn't
resolve them all either but it does fix up a few, and it excludes
the others so 'make checkstyle' no longer prints warnings.  It's
a small step in the right direction.

* Dracut is Linux specific and itself depends on bash.  Therefore
  all dracut support scripts can be bash specific, update their
  shebang accordingly.

* zed-functions.sh, zfs-import, zfs-mount, zfs-zed, smart
  paxcheck.sh, make_gitrev.sh - these scripts were excuded from
  the check until they can be updated and properly tested.

* zfsunlock - only whole values for sleep are allowed.

* vdev_id - removed unneeded locals; use && instead of -a.

* dkms.mkconf, dkms.postbuil - use || instead of -o.

Change zfsunlock for better busybox compatibility
It turns out that there are two versions of Busybox, at least on Ubuntu
18.04.  If you have the busybox-static package installed, you get a
busybox that supports `ps a` and `head`.  If you only have
busybox-initramfs, you don't.  Either way, you have `awk`.

This change should also make this compatible with GNU ps, if you somehow
end up with that in the initramfs environment.

4cfd339ce4 Cleanup contrib/initramfs automake
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.

5ecbb293c6 Fix zfs-functions packaging bug
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
