During raid assembly mdadm will call mdadm-grow-continue.service if
reshape is in progress.
If service doesn't exist then it is done via fork and systemd will kill
it unconditionally after processing all events.
Add proper service to allow systemd to manage reshape correctly.

For the shell scripts, new environment variables were introduced.
dracutsysrootdir is the root directory, file existence checks use it.
DRACUT_LDCONFIG can override ldconfig with a different one that works
on the sysroot with foreign binaries.
DRACUT_LDD can override ldd with a different one that works
with foreign binaries.
DRACUT_TESTBIN can override /bin/sh. A cross-compiled sysroot
may use symlinks that are valid only when running on the target
so a real file must be provided that exist in the sysroot.
DRACUT_INSTALL now supports debugging dracut-install in itself
when run by dracut but without debugging the dracut scripts.
E.g. DRACUT_INSTALL="valgrind dracut-install or
DRACUT_INSTALL="dracut-install --debug".
DRACUT_COMPRESS_BZIP2, DRACUT_COMPRESS_LBZIP2, DRACUT_COMPRESS_LZMA,
DRACUT_COMPRESS_XZ, DRACUT_COMPRESS_GZIP, DRACUT_COMPRESS_PIGZ,
DRACUT_COMPRESS_LZOP, DRACUT_COMPRESS_ZSTD, DRACUT_COMPRESS_LZ4,
DRACUT_COMPRESS_CAT: All of the compression utilities may be
overridden, to support the native binaries in non-standard places.
DRACUT_ARCH overrides "uname -m".
SYSTEMD_VERSION overrides "systemd --version".
The dracut-install utility was overhauled to support sysroot via
a new option -r and fixes for clang-analyze. It supports
cross-compiler-ldd from
https://gist.github.com/jerome-pouiller/c403786c1394f53f44a3b61214489e6f
DRACUT_INSTALL_PATH was introduced so dracut-install can work with
a different PATH. In a cross-compiled environment (e.g. Yocto), PATH
points to natively built binaries that are not in the host's /bin,
/usr/bin, etc. dracut-install still needs plain /bin and /usr/bin
that are relative to the cross-compiled sysroot.
The hashmap pool allocate_tile/deallocate_tile code was removed
because clang-analyze showed errors in it. hashmap_copy was removed
because it wasn't used and clang-analyze showed errors in it.
DRACUT_INSTALL_LOG_TARGET and DRACUT_INSTALL_LOG_LEVEL were
introduced so dracut-install can use different settings from
DRACUT_LOG_TARGET and DRACUT_LOG_LEVEL.

Add new functions require_binaries() and require_any_binary() to be used
in the check() section of module-setup.sh.
These functions print a warning line telling the user, which binary is
missing for the specific dracut module.
This unifies the way of checking for binaries and makes the life of an
initramfs creator easier, if he wants to find out why a specific dracut
module is not included in the initramfs.
mdadm-3.2.6+:
Incremental assembly rule contains "--offroot" arg. Update
regexp to catch this variant.
mdadm-3.3+:
Rules was splitted into two files: 63-md-raid-arrays.rules
and 64-md-raid-assembly.rules. Install them both and edit
the latter.
This prints the kernel command line parameters for the current disk

Correctly return the check functions, so we have a valid return of

mdraid and dmraid functions had wrong checkings for the filesystem

Like -H, we need to poll every module to check if it is needed
to mount a specific device in '--mount'.

Reworked the flow of the rules file a bit, removed redundant tests, also
should be easier to follow. It's much shorter now as well, a bit more
similar to 90lvm script - both revolve around same concepts after all.
There's no reason to treat conf-assembled arrays differently from
incremental ones. Once we hit timeout in init's udev loop, we can use
common script (mdraid_start.sh) to try force inactive arrays
into degraded mode.
md-finished.sh was kind-of out of place - it didn't really wait for any
particular device(s) to show up, just watched if onetime mdadm scripts
are still in place. Furthermore, after moving mdraid_start to --timeout
initqueue, it didn't really have too much to watch at all, besides
mdadm_auto (and that served no purpose, as we do wait for concrete
devices).
Either way, with stock 64-md fixes, current version of 65-md*.rules does
the following:
- limits assembly to certain uuids, if specified
- watch for no ddf/imsm
- if mdadm.conf => setup onetime -As script, without forced --run option
- if !mdadm.conf => incrementally assemble
- for both cases, setup timeout script, run-forcing arrays as a last resort

1) mdadm -As --auto=yes --run 2>&1 | vinfo (removed)
Currently such auto assembly will not complete or force-run partially
assembled arrays. It might assemble "concurrent" separate array and
force-run it, if possible (though the chances of suddenly showing
missing components in this scenario - a script run after udev timeout -
are pretty thin). See [1] for details. Also see #3 below.
2) mdadm -Is --run 2>&1 (removed)
This will only force-run native arrays - arrays in containers will not
be affected. See [1] for details. Also see #3 below.
3) mdadm -R run loop (implicitly handles #1 & #2)
This loop does everywthing that #1 & #2 are expected to do. Thus, the
above invocations are simply redundant and this is the most safe and
flexible option.
Also, it shouldn't be necessary to go under md/ directory, as those are
just symlinks to /dev/md[0-9]*.
Certain checks were changed to strict ones (array state, degraded state)
instead of relying on env tricks.
'cat' was added explicitly to installed programs (it has been used
implicitly in shutdown script either way)
4) mdmon bug
See [1] for details as well. In short - force-run arrays in containers
will not have mdmon started, so we do that manually.
5) stop/run queue magic
Also removed. mdadm -R will only cause change events to the array
itself, and they should not be an issue.

Remove whole "start a container logic".
Containers once assembled, always remain in 'inactive' state.
Any attempt to run a container with mdadm -IR is a no-op, and any
attempt with just mdadm -R ends with an error.
