Release v4.6.3

This release fixes mixer to not exit when upstreamurl is not found, and
to attempt to use the given format in the builder.conf. For some cases,
the mixer user may in fact be "upstream" so it does not make sense to check
upstream format compatibility.
A new tool is available called swupd-inspector, which contains various
commands that help read data of a swupd repository: download the fullfile for
a specific file, see the Manifest for a specific version, see the differences
between two versions.
