ismounted handles both find-by-dev and find-by-mnt, but there's two issues:
1. for find-by-dev, it use readlink to get the canonical dev name, but
lvm is different with other devices, the canonical name for lvm devices
are symlinks like /dev/mapper/vg-lv00
2. for nfs mounting, just use [ -b $dev ] is not enough, it need being handled
seperately.
Per Karel Zak's suggestion, findmnt util is suitable for this purpose, it
handles these cases well, so just use findmnt instead of implement all the
logic by ourselves. Thanks, Karel.

kdump module also need to convert dev name to udev symlinks.
So better to move function get_persistent_dev() to dracut-functions.sh
Also in this patch improvement and fix the original function:
a) use udevadm info --query=name to get the kernel name.
This will fix the issue caused by passing symbolic link of a device.
b) fix a bug to compare $_tmp instead of $i with $_dev. Really sorry,
should have tested more carefully.

each dev in host_devs[] should be waited in initqueue to make sure they
are oneline before initqueue finish.
Add a new wait_host_devs.sh in base module to make this a generic thing.
Because all the devs in fstab lines are also added to host_devs, so no need
do same wait in fstab-sys module anymore.
[v2->v3]: do not add slave devices to host_devs
wait for persistent dev name in initramfs

if you add realinitpath="<path1> <path2>" to dracut.conf, then it will
be written to $initdir/etc/cmdline.d/distroinit.conf with
"rd.distroinit=<path1> rd.distroinit=<path2>" and evaluated by
99base/init, when it searches for init.
Option --ctty will optionally add setsid binary to dracut's image.
During runtime, if rd.ctty is set and is a character device,
emergency shells will be spawned with job control.
in case no ctty was provided, shell was spawned without caring about
/dev/console. Also, the ctty is more opportunistic. If the image was
generated with --ctty, we will fallback to /dev/tty1 if rc.ctty is
invalid or missing. Otherwise we spawn standard shell on /dev/console

ssh module will need root user in /etc/passwd, so add root and nobody
to /etc/passwd in 99base instead of nfs module

We want all "/var/run" information to live in /dev/.run, until the real
root is mounted.
Therefore we mount a tmpfs on /dev/.run, which can/will be bind/move mounted
on /var/run later on.
