Create a standalone awk script, depends-depth-first.awk, that encapsulates
the code that performs the dependency graph traversal (in depth-first
fashion). This script has a hook that allows executing a shell command
line upon visiting a dependency's package directory in either prefix
or postfix order, and may be used to simplify the code in bsd.pkg.mk
that iterates over dependencies.
This awk script requires the target "show-depends-pkgpaths", which is
defined in a new Makefile pkgsrc/mk/bsd.utils.mk. This file should
accumulate "utility" targets that current exist in bsd.pkg.mk, i.e.,
"helper" targets for various actions.
