Avoid potential races with other threads reading features that do not share a lock while features are temporarily null.
Special handling for proto1 mutable should not actually be needed, since setProto doesn't update dependency protos.

This change keeps the existing naming for properties generated from proto2 files, while improving the experience under editions. This introduces a C# incompatibility when upgrading a proto from proto2 to editions, but we anticipate this being a relatively rare problem.

GPB_ENUM_FWD_DECLARE needs `int32_t`, so add the import so GPBBootstrap.h
stands on its own without needing users to import something else.
Add another compile test file to ensure this doesn't break.

JUnit4 does not support nested tests so these weren't running. Fixes setup problems and test logic. Oneof fields now inherit from their oneof, and top-level extensions inherit from top-level file when parent descriptor is null.

The non-string field setters can bypass the vtables already, the string setters still go through the vtable path here because its more important to let them take an `impl SettableValue` to be able to set either a &str or a &ProtoStr already.

The actual construction of the zeroed block is now entirely safe.
This will be accessed in nearly every program using protobuf.
Using a static in .bss has much less overhead than an atomically-constructed
dynamic allocation and is far more predictable for space-constrained systems.
In the future, if dynamic allocation is kept, it should use std::sync::OnceLock
instead of the much less safe Once combined with `static mut`.

It now uses the same prefix as other thunks needed for the proxied type,
so the RawMapThunk helper can be used for enums.
Calling it a "iter next" thunk is misleading.
It does not increment the iterator as "next" implies,
it only gets the current key/value the iterator points to.

The purpose is to avoid duplicating the mapping of different types that are only relevant to the serializer but not to the exposed api (e.g. FIXED32 vs INT32)
Treat type=GROUP as rust-type=MESSAGE here which is all that is needed for us to support groups in the rust codegen.
The RustFieldType is parallel to the preexisting FieldDescriptor::CppType which _almost_ does what we need, but it treats Bytes and Strings as the same cpptype which Rust codegen doesn't.
