`unsafe trait` means that the _implementation_ has constraints they need to meet for the behavior to be safe (which is the intent here, namely that it should always return the same value and always be a safe to deref value), unsafe on the fn means that the _caller_ of that fn has some constraints they need to meet for it to be safe (of which there are none in this case).

Distinct from any clear_submsg(), this clears the message contents and doesn't affect presence on parent (and also allows for clearing owned messages which don't exist as a field to be cleared).

Adds a new 'bzl' feature that is used to adjust import paths that need to change
in the Cargo build vs Blaze build.
This protobuf rust crate is a single crate that merges all of our current crates (protobuf, rust/upb, and utf8).

General test for it is done in Rust, and then extensions are tested in UPB as they're not currently supported in Rust-upb.

`Vec<u8>` is a more idiomatic Rust type to return for serialization.
For the C++ kernel, we are able to return this type with no extra copying. We
still use `SerializedData` type for FFI, but convert the result into a
`Vec<u8>` using a new `into_vec` method.
The upb kernel serializes onto an arena, so for upb we do need to copy the data
to get it into a `Vec<u8>`.

We modify set_<repeated_field> to accept the IntoProxied type as the value and move the value (avoid copying) whenever possible.
For UPB:
- We fuse the arena of Repeated<T> with the parent message arena.
- We use upb_Message_SetBaseField to set the upb_Array contained in the Repeated<T>.
For C++:
- We generate an additional setter thunk that moves the value.
- The move assignment operator of RepeatedField/RepeatedPtrField is specialized. In order to adhere to the layering check we need to add '#include' statements for all .proto imports to the generated thunks.pb.cc.

The intent of this directory would be for a layer of Rust bindings that directly map to upb semantics; Rust Protobuf runtime would be layer on top of that Rust, instead of directly on the upb C api.
