package-installs for pre-install.d/post-install.d Packages are often also installed in both the pre-install.d and post-install.d phases. This patch expands the package-installs element to support declarative package support for these phases in addition to the existing support for install.d. The actual install/uninstall logic is moved to common scripts under bin/ so that it can be reused across the different phases.

Package installs defaults to tracing off There isn't a good reason we should be defaulting to trace on for these scripts. Change-Id: I1b9ac9388f51a49e6912d800914a0e0f2faec604 2015-12-20 00:03:51 +00:00			`if [ ${DIB_DEBUG_TRACE:-0} -gt 0 ]; then`
Standarise tracing for scripts There is a wide variety of tracing options through the various shell scripts. Some use "set -eux", others explicity set xtrace and others do nothing. There is a "-x" option to bin/disk-image-create but it doesn't flow down to the many scripts it calls. This adds a global integer variable set by disk-image-create DIB_DEBUG_TRACE. All scripts have a stanza added to detect this and turn on tracing. Any other tracing methods are rolled into this. So the standard header is --- if [ "${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.

Rework package-installs to collapse on build host Instead of doing the work in the image of parsing through the element's package-install declarations, we can squash it on hostside, where we have both YAML and JSON available to us, and then emit a single pre-processed file into the target to be used later.
