FFE: Sync appstream-generator 0.7.1-3 (universe) from Debian unstable (main)

Please sync appstream-generator 0.7.1-3 (universe) from Debian unstable (main)

This new release brings a ton of improvements to the AppStream metadata generation process and fixes lots of old bugs, so having it in the Bionic LTS release would be very useful so users (and Ubuntu itself) can generate high-quality AppStream metadata.

Updating appstream-generator means that appstream itself needs to be updated first. Updating appstream-generator has a very low (if not zero) regression potential, since nothing depends on it and the new version has received extensive testing on Debian's infrastructure and on Arch Linux.
Updating appstream itself is introduces new features and API, and its FFE is tracked as LP: #1762292 - if that FFE for appstream is not granted, appstream-generator can not be updated.

Updating appstream-generator also requires minor updates of gir-to-d and (optionally) mustache-d (packages only used by appstream-generator in Debian/Ubuntu).
