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.

As with the previous similar changes, this is intended to catch
problems as they happen instead of ignoring them and continuing on
to potentially fail later. Setting this on all existing scripts
will allow us to enforce use via Jenkins.

Currently the dpkg element fakes start-stop-daemon, initctl and
invoke-rc.d to stop dpkg from starting a bunch of daemons in the
chroot. This is problematic when packages use service, start, stop or
restart commands.
This patch uses a policy-rc.d instead of faking invoke-rc.d to achieve
the same thing. This approach now aligns exactly with debootstrap.
Without this patch DIB runs on some debian distributions fail
when trying to umount the chroot loop device as there are daemons
running.
The log will now show "invoke-rc.d: policy-rc.d denied execution of
start." instead of "Warning: Fake invoke-rc.s called, doing nothing."

Check if Upstart exists before blocking the daemon. Not all dpkg based
OS's have Upstart installed so this should help increase compatibility.

This includes the install-packages implementation for dpkg, apt http proxy
config, daemon blocking and unblocking.
