commit aa5a2548dc1c16448b50cb6847aabbefd600b7f9
Author: Patrick Griffis <pgriffis igalia com>
Date: Sun Jun 19 15:48:02 2022 -0500
WebExtensions: Implement the downloads API
This is a almost entire implementation of this API.
Some limitations:
- WebKit doesn't support pause/resume
- WebKit doesn't inform us of writes, so we don't know mid-download the size on disk
- Download information is persistent across sessions in other browsers, they are lost with Epiphany
- I haven't fully mapped all GIO errors to WebExtension errors
