It only remained on FwupdResult because I couldn't make up my mind about whether
it was a property of the device, or the firmware release. It's more logically
the latter, as you could have a .cab file with multiple versions of the
firmware and only the first being signed.
This was only ever added for gnome-software, and is too inflexible for anything
else. It turns out we don't even need it in GNOME, as we can construct a
suitable ID ourselves using the existing values.
It was also ambiguous whether the unique ID was in reference to the device
or release -- and for gnome-software we need both.

the former, and that's how plugins are using it.
This does two things:
* Allows new users of the library to see only the supported symbols
* Allows us to ensure we're not using deprecated API internally
I can also use this in gnome-software in CI to make sure we're not using
deprecated API too. I don't think we're ready for a soname bump so we have to
hang on to the deprecated code for now.
Although we supported other hashes than SHA1 (which is now moderately unsafe)
we had to switch the metadata provider and daemon on some kind of flag day to
using SHA256. Since that's somewhat impractical, just allow multiple checksums
to be set on objects and just try to match whatever is given in preference
order.
This also means we can easily transition to other hash types in the future.
The removed API was never present in a tarball release, so not an API break.
This functionality is required so that AppStream metadata can check the fwupd
version, the firmware version, bootloader version or a combination of all three.
This allows us to return multiple results from one file, for instance where the
firmware.cab file contains multiple metainfo.xml files.
This allows us to show all the entries in the firmware file, rather than
searching for the installed device that matches and falling back to just the
first listed item.
