Commit Message

Bartosz Golaszewski June 28, 2024, 2:53 p.m. UTC 
From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

In order to allow the upcoming GLib and DBus bindings to reuse the test
code, let's put all common elements into reusable libtool objects and
export the relevant symbols in internal headers.
