Update:
- UniFFI to 0.27.1
- Glean to 59.0.0
- App-services to a recent version
This removes the need for the goblin build hack, although we still have
duplicate versions of goblin since UniFFI is ahead of the moz-central
version. I think that should be easy to resolve as a follow-up.
Updating uniffi-bindget-gecko-js based on upstream changes:
- Clone objects before lowering them
(https://github.com/mozilla/uniffi-rs/pull/1880)
- Use u64 for the RustBuffer length and capacity field
(https://github.com/mozilla/uniffi-rs/pull/1978)
I didn't implement the new callback interface VTable code. Instead I
simply disabled the one fixture that tests it. I'd rather implement
https://bugzilla.mozilla.org/show_bug.cgi?id=1888668 first, since that
will simplify the process a bunch. The only real-world use-case for
callbacks that I know of is Mark's logging changes, but that will
require implementing trait interfaces anyways so I'd rather wait than
write a bunch of C++ code that we then throw away.
