3c6972a5c0 Turn down some low-value tracing output
There are a couple of loops identified here that output a lot of
tracing each iteration for little value.  Make them only trace at
higher levels (-x -x and above).

Points of actual interest within the loops are replaced with an
explicit "echo" statement.

Additionally, export DIB_DEBUG_TRACE explicitly and in all cases, not
just when tracing is turned on.

36b59c001c Standarise tracing for scripts
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.

4178c0c69d Deprecate map-packages, replaced by pkg-map
This patch writes a warning out to stderr to notify element authors
that may be using map-packages to migrate to pkg-map.  This patch
also prints out a warning during image-create that lists the specific
elements that are not using pkg-map.

c55539b142 Add pkg-map element.
Adds a new pkg-map element which can be used to install
packages based on an in element 'pkg-map' JSON config
file format.

As part of this change we expose DIB's IMAGE_ELEMENT variable
so that we can have access to the element names which are being
installed in a clean manner.

This change is intended to decouple elements from DIB
and allow new elements to support multiple distributions
(with various package naming schemes) without having to
constantly maintain DIB's various bin/map-packages files.
