libappstream-glib is mostly unmaintained, and libappstream is more
actively developed (and up to date with the AppStream specification).
Port from libappstream-glib to libappstream. Handily, a lot of the APIs
are exactly the same. The main changes are:
* `AsApp` → `AsComponent`
* `AsStore` → `AsMetadata`

The history command seems to have been broken since it was changed to
use FlatpakDecomposed, since that type only works for app or runtime
refs, resulting in errors such as:
$ flatpak history
error: appstream2/x86_64 is not application or runtime
Fix this by making the logic a bit smarter, and don't let any one
invalid ref entry prevent the whole command from working.
Fixes#4332
flatpak-utils.c is getting large, and also I got some issues with
include order, so split out things that are purely handling ref stings
in various ways to its own file.
