It is reasonable that elements may need to include additional
kernel modules in a dracut ramdisk. This is done with the
--add-drivers option to dracut, but previously the value passed
was hard-coded.
This change allows an element to put a file containing its desired
drivers in a dracut-drivers.d directory, and the list there will
be added to the list of drivers added. This functions in
essentially the same way as the binary-deps.d directory that
already exists for including additional executables in a ramdisk.

There is a wide variety of tracing options through the various shell
scripts. Some use "set -eux", others explicity set xtrace and others
do nothing. There is a "-x" option to bin/disk-image-create but it
doesn't flow down to the many scripts it calls.
This adds a global integer variable set by disk-image-create
DIB_DEBUG_TRACE. All scripts have a stanza added to detect this and
turn on tracing. Any other tracing methods are rolled into this. So
the standard header is
---
if [ "${DIB_DEBUG_TRACE:-0}" -gt 0 ]; then
set -x
fi
set -eu
set -o pipefail
---
Multiple -x options can be specified to dib-create-image, which
increases the value of DIB_DEBUG_TRACE. If script authors feel their
script should only trace at higher levels, they should modify the
"-gt" value. If they feel it should trace by default, they can modify
the default value also.
Changes to pachset 16 : scripts which currently trace themselves by
default have retained this behaviour with DIB_DEBUG_TRACE defaulting
to "1". This was done by running [1] on patch set 15. See the thread
beginning at [2]
dib-lint is also updated to look for the variable being matched.

Copy all of TMP_MOUNT_PATH into the ramdisk so that
ramdisk-install.d actions are respected.
Includes a workaround for a bug in Dracut that caused the copy
to fail.
Also moves init instead of copying it so we don't conflict with
the Dracut init.

A similar change was needed in the normal ramdisk element as part
of ae928057bd to avoid running
cleanup immediately after the ramdisk build completes.

Instead of hard-coding a list of binaries to include in the dracut
ramdisk, use the existing binary-deps.d functionality to provide a
list. This will allow other ramdisks (such as discovery) to add
the binaries they need.

The element builds dracut from source on Ubuntu because the
Ubuntu dracut package is broken and very old, so it can't be
installed properly and causes a number of other issues that
are fixed by using a newer version of Dracut.
This initial version should work in virtualized environments.
Further validation of its suitability for real baremetal
deployments will need to be done in the future, but this should
be sufficient to enable that work.
Regarding Dracut specifically, in order to limit the changes
needed in the existing scripts this element continues to use a
cut down version of the /init script that we were building for the
existing ramdisk. However, instead of running it as pid 0 it is
run as a Dracut pre-mount hook. This allows Dracut to set up all
of the hardware and system bits, while falling early enough in the
Dracut sequence to complete the deployment before Dracut would try
to boot off the hard disk.
