So far, everything parsed root= manually, which meant that while
zfs-parse.sh was updated, and supposedly supported + -> ' ' conversion,
it meant nothing
Instead, centralise parsing, and allow:
root=
root=zfs
root=zfs:
root=zfs:AUTO
root=ZFS=data/set
root=zfs:data/set
root=zfs:ZFS=data/set (as a side-effect; allowed but undocumented)
rootfstype=zfs AND root=data/set <=> root=data/set
rootfstype=zfs AND root= <=> root=zfs:AUTO
So rootfstype=zfs /also/ behaves as expected, and + decoding works

It was added in the original ae26d0465a ("Add dracut support") commit
in 2011, and was then broken a bit later with the advent of
dracut-zfs-generator, or maybe earlier as part of other churn
Either way, it's broken, and has been in 2.0+ as well, and no-one
complained. Stop pretending we support it at all

- Remove `SHELLCHECK_IGNORE` in favor of inline suppressions
and more general `SHELLCHECK_OPTS`.
- Exclude `SC2250` (turned on by `--enable=all`) globally
- Pass `--enable=all` to shellcheck for scripts in contrib/: it's
very important to catch errors early in areas that are not easily
testable.

Closes#12760
Despite that dracut has a hard dependency on bash,
its modules doesn't, dracut only has a hard dependency on bash for
module-setup (on a fully usable machine). Inside initramfs, dracut
allows users choose from a list of handful other shells, e.g. bash,
busybox, dash, mkfsh.
In fact, my local machine's initramfs is being built with dash,
and it's functional for a very long time.
Before 64025fa3a (Silence 'make checkbashisms', 2020-08-20), we also
allows our users to have that right, too.
Let's fix the problem 'make checkbashisms' reported and allows our users
to have that right, again.
For 'plymouth' case, let's simply run the command inside the if instead
of checking for the existence of command before running it, because the
status is also failture if plymouth is unavailable.
While we're at it, let's remove an unnecessary fork for grep in
zfs-generator.sh.in and its following complicated 'if elif fi' with
a simple 'case ... esac'.
To support this change, also exclude 90zfs from "make checkbashisms"
because the current CI infrastructure ships an old version of
"checkbashisms", which complains about "command -v", while the current
latest "checkbashisms" thinks it's fine. In the near future, we can
revert that change to "Makefile.am" when CI infrastructure is updated.

It was discovered that dracut scripts and zgenhostid
always generate little-endian /etc/hostid.
This commit provides simple endianess-aware binary
and updates the scripts to use it.
New features include:
-f flag to force overwrite.
-o flag to write to different file (for dracut)
accepting both 0x01234567 and 01234567 values as input

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.

Since the `cut -b` command is used by `parse-zfs.sh`,
ensure that it is copied to the initramfs.
Fix spl_hostid when set by cmdline. This follows a
similar logic from the `zgenhostid` script, using `echo`
instead of `printf`.

PR #8114 quoted the ${ENCRYPTIONROOT} parameter to ensure we don't
lose spaces when unlocking root filesystem in the off chance that
it has a space in its name.
Unfortunately, dracut and initramfs-tools do not actually get the
quotes from the cmdline. If we use root=ZFS="root pool/filesystem
name" the script still only sees root=ZFS=root and no quotation
marks.
Because + is a reserved character in ZFS, it's used as a
placeholder for spaces in the kernel cmdline. In this way,
root=ZFS=root+pool/filesystem+name will properly expand by
replacing the character with sed (POSIX compliant method).
