Because environment files are sourced into the current environment,
they shouldn't be setting global settings like tracing else they
affect every preceeding import. This is quite confusing when only
half your imports are traced in the logs, because it was either turned
on, or off, by a preceeding environment import.
There is a corresponding dib-run-parts change in
I29f7df1514aeb988222d1094e8269eddb485c2a0 that will greatly increase
debugability for environment files by deliberately logging what files
are sourced and consistently turning on tracing around their import.
This isn't strictly necessary (since dib-run-parts with the prior
change will just turn tracing off after import anyway) but it's a
decent cleanup for consistency. A bare-minimum dib-lint check is
added. Documentation is updated.

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.

15-pip-manifests depends on the variables defined by the manifests
element, so we need to run this one earlier. I would have thought things
were alpha sorted after the numerical sort...but I just ran into this,
so apparently not.
