This is needed since few gpio/pinctrl can be built as modules and are
useful on early boot.
One example is jetson-tx1 where sata and external mmc can work only
after loading pinctrl-max77620 and gpio-max77620 modules.
Having theses kind of drivers bundled into the initramfs will also
avoid some deferred probes.
V2: add pinctrl for all arches

Currently, when trying to unpack or print the content of multiple
files, lsinitrd will decompress the image and pipe the decompressed
content to cpio to retrive each file if the image is compressed.
Which mean if we want to extract 10 files the image will be decompressed
10 times, which is a waste of time.
This patch will let lsinitrd decompress the image file to a temp file
first if multiple file names are given, then cpio will read from the
decompressed temp file, which will speed up a lot.
Time consumption test for command:
`lsinitrd initramfs-4.16.15-300.fc28.x86_64.img \
usr/lib/dracut/build-parameter.txt \
usr/lib/dracut/modules.txt \
etc/machine-id \
etc/hostname \
usr/lib/udev/rules.d/99-systemd.rules`
Before the patch:
2.37user 0.33system 0:02.12elapsed
After the patch:
0.50user 0.42system 0:00.72elapsed
There would be a more significant time difference if we try to
extract more files.
Before this patch, "--unpack" will always unpack the whole image.
Make "--unpack" be able to unpack only certain files, it will be
easier to retrieve files from initramfs image.

Add module for setting correct timezone.

For now, this module will not be included automatically due to different
expectations (see e.g. https://bugzilla.redhat.com/show_bug.cgi?id=981617)

A hostonly image will not include every possibly required kernel module,
so if any hardware or configuration changed, the image may fail to boot.
One way to know if there are any hardware change or configuration change
that will require an image rebuild or not is to check the loaded kernel
module list. If the loaded kernel module list differs from last build
time, then the image may require to be rebuilt.
This commit will let dracut record the loaded kernel module list when
the image is being built, so other tools or services can compare this
list with currently loaded kernel modules to decide if dracut should be
called to rebuild the image.
To retrieve the loaded kernel modules list when an image is built, use
lsinitrd command:
lsinitrd $image -f */lib/dracut/loaded-kernel-modules.txt
if rd.md.uuid is in ID_FS_UUID format with dashes
e40a0234-7e52-5f10-f267-658d8ec463fa
convert it for the /dev/disk/by-id/md-uuid-${uuid} format

Check for a common binary in systemdutildir. This resolves an issue on
split-usr systems, where it is common to have both /lib/systemd[/system]
and /usr/lib/systemd[/user] present.
Check for systemd-udevd specifically, since some distros (Gentoo) allow
udev to be installed without the rest of the systemd stack.
Similar logic is applied to udevdir simply for consistency.
This commit basically reverts 5ce7cc73
90-multipath-hostonly module was added in 5ce7cc73, because if hostonly
mode is enabled, multipath module will always hardcode wwids which
causes problems when the initramfs is cloned to another system with same
hardware.
Now with tri-state hostonly mode, the two modules could be merged and only
hardcode wwids when "strict" hostonly mode is enabled.
Only pick rules for interfaces which have a carrier in the running
system. Those interfaces will be assembled by udev to allow booting
from those devices (i.e. iSCSI).
Reference: FATE#323440
Add a new option --hostonly-mode which accept an <mode> parameter, so we have a tri-state hostonly mode:
* generic: by passing "--no-hostonly" or not passing anything.
"--hostonly-mode" has no effect in such case.
* sloppy: by passing "--hostonly --hostonly-mode sloppy". This
is also the default mode when only "--hostonly" is given.
* strict: by passing "--hostonly --hostonly-mode strict".
Sloppy mode is the original hostonly mode, the new introduced strict
mode will allow modules to ignore more drivers or do some extra job to
save memory and disk space, while making the image less portable.
Also introduced a helper function "optional_hostonly" to make it
easier for modules to leverage new hostonly mode.
To force install modules only in sloppy hostonly mode, use the form:
hostonly="$(optional_hostonly)" instmods <modules>
