Currently in initrd, hardware clock is always considered to use UTC time
format and system time zone is also UTC. Thus system time isn't correct
if hw clock is localtime or we're using other time zone in real root.
To fix this, install /etc/adjtime and /etc/localtime to initrd. If not
using systemd, install /usr/sbin/hwclock for dracut init to setup system
time.

Currently the default action is emergency_shell when failure happened
during system boot. In kdump, this default may not be expected. E.g,
if dump target is not rootfs, it does not matter if mount root failed.
Adding an action which allow dracut always go ahead though failure
happens is needed by kdump.
So here add a function action_on_fail() and cmdline parameter
action_on_fail=<shell | continue>. Use action_to_fail() to replace
emergency_shell which was called after failure. By $(getarg action_on_fail=),
decide to drop into shell, or to leave away the failure and go ahead.
v3->v4:
add handling of selinux policy loaded failure, and change code format to
be consitent

Previously I added several trace point to the begin of several
init hooks of systemd, old init script also need this debug info.
Doing same here as what's added in the systemd service scripts:
At cmdline hooks adding trace of "1+:mem 1+:iomem 3+:slab"
For other hooks adding trace of "1:shortmem 2+:mem 3+:slab"

When dracut-lib.sh is sourced it checks the command line (when not using systemd)
as part of the check_quiet() call.
Therefore mount /proc earlier in init.
Avoids the error:
init: 77: /lib/dracut-lib.sh: /proc/cmdline: No such file or directory
Starting with commit 24a38bc1cb dracut
uses udev builtins but still depends on >=udev-166 in dracut.spec. This
patch makes dracut work with older udev again.

Sometimes some hook script will need to be before the cleanup hook scripts
For example dhclient killing, nfs cleanup, etc. must not happen before kdump
because it will use their fuctionalities.
So here introduce a new hook pre-pivot-cleanup, all cleanup scripts will go there.
that means pre-pivot hook is splited to two hooks pre-pivot and pre-pivot-cleanup

"export -n" is a bash extension, not part of POSIX, and is hence
incompatible with the busybox shell.
This was breaking boot when the busybox module was used.
Reimplement the scope change in a few lines of standard shell code.
