Kdump support dump to raw device which could be on top of complex storage
such as multipath and iscsi which are standalone dracut modules.
Add a --device option to dracut which will add the device to host_devs so
dracut can add the dependent modules automaticlly and enable them in initramfs.
--device will accept device node name as the param.

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

We do not want to install dracut-install to /usr/bin until all
interfaces are set to stone and the manpage is written. Until then the
tool is dracut internal.
First, we just install the kernel module and keep track, what we
installed. At the very end, call modprobe and modinfo for firmwares to
resolve all kernel module dependencies. This speeds up image creation,
because we can call modprobe and modinfo with many modules.
We should not trust cmdline passed by users, always
check the install files passed from cmdline. This restores
the old behaviour which was changed by:

This patch adds check of kernel module existance and
propagate errors to upper callers.
In case of break other callers of instmods(), this patch
adds an option '-c' to it, only when "-c" is specified
we fail, otherwise, errors are ignored.
