Default action is 'build' unless overridden in builder_describe.
Default target is all targets when no target is specified in command-
line.

auto: increment master version to 16.0.40

This change also slightly modifies `echo_heading` and outputs a
mark. This will show to the left of the line as well as in the
scroll bar in a terminal in VSCode [[1]] and will help to find the
headings if you have a lot of output in between.

chore(linux): Update debian changelog 🍒

builder_init was unnecessarily and inconsistently duplicating
builder_describe and builder_parse functionality. Removing it -- all
scripts should use builder_describe and builder_parse instead, which
gives us more flexibility and consistency into the future.
