Add the helpers vopt_if, vopt_with and vopt_enable that simplify common
option-based operations.
Instead of a bunch of
if [ "$build_option_foo" ]; then
configure_args+=" --with-foo"
makedepends+=" foo-devel"
else
configure_args+=" --without-foo"
fi
one can use
configure_args="... $(vopt_with foo)
makedepends="... $(vopt_if foo foo-devel)"
instead.
We're adding these functions to common/xbps-src/shutils/common.sh but
that might not be the ideal place. I would've preferred
common/helpers/options.sh, but helpers are only available in the
individual phases, not when the template itself gets parsed.
