If a proto_library has more than one srcs, we designate the first one as the primary (that file will be passed to rustc as the crate root). All other files will represent (internal) submodules of the crate.
In general, Rust users won't see which .proto file a message came from, they will only see a crate corresponding to the entire proto_library, and in it public submodules for all `package` statements in all .proto files in the proto_library sources. Therefore in this CL we reexport all messages from non primary sources into their corresponding public modules (= packages declared in their owning .proto files).
Besides the common case this CL also handles .proto files without package statement, and a subset of behaviors needed for public import functionality.

This optimizes non const and copy initialization of arena string values. String hardening is automatically performed on as needed by the ArenaStringPtr class, removing the need for extra clutter or set operations added by the protocol compiler in generated code.

Only handles proto2 syntax atm, but I couldn't find any other implementation of something that seemed rather simple and sometimes useful, to integrate with third-party tools meant to run directly on .proto files.
Example usage: `protoc Example.proto --descriptor_set_in file_descriptor_set.pb --proto_out .`

This adds `#![deny(unsafe_op_in_unsafe_fn)]` which removes the
implicit `unsafe` block that `unsafe fn` does.
It also adds many more `SAFETY` docs, corrects some incomplete
ones, and catches a null pointer returned by `upb_Arena_New`.

This is just cruft used for selectively rolling out the editions changes. Since it's not tested, it would be dangerous to keep it in place.
PiperOrigin-RevId: 547979600
Editions are still flag-guarded by the `--experimental_editions` flag for now, but once that's removed in a later release generators will need to explicitly specify that their support. This will avoid cases where generators may happen to work for editions but produce incorrect code.

There are 4 different feature sets for every descriptor:
* Runtime/resolved - Used to make runtime decisions
* Source/resolved - Used to make codegen decisions
* Runtime/unresolved - Used to reason about the original proto file during runtime
* Source/unresolved - Used to validate features during codegen
Plugins will receive all 4 of these. Unresolved features will show up in the `raw_features` fields nested inside `features`. The runtime features will be in the `proto_file` field of the request, while the source features will be in the unstripped `source_file_descriptors` field.

There are 4 different feature sets for every descriptor:
* Runtime/resolved - Used to make runtime decisions
* Source/resolved - Used to make codegen decisions
* Runtime/raw - Used to reason about the original proto file during runtime
* Source/raw - Used to validate features during codegen
All of these will need to be shipped to code generators. While C++ generators can use the C++ runtime to reconstruct these, they won't end up in the FileDescriptorProtos we send to runtimes. Similarly, non-C++ generators wouldn't be able to get them without duplicating our feature resolution logic. This change adds a helper that allows us to bundle all of these into the protos we send to generators.

The `unittest_proto3_bad_macros.proto` test is failing on FreeBSD due to the GID_MAX/UID_MAX macros. This is because `port_def.inc` is missing these entries (as well as TRUE/FALSE) for FreeBSD. This PR adds those missing macros.

This will be used for tracking the unresolved feature sets from the original proto file. Notable use-cases for this include:
* Code generators that need to validate their own features
* Runtimes that need to be able to accurately round-trip the original protos

These are invalid for UPB which uses immutable string views.
This also adjusts some docs:
- removes a promise in the language of `truncate`
that no reallocation will occur.
- removes language about DerefMut and replaces the `&mut Vec<u8>` analogy

MSVC compilers generate warnings that the default destructor is implicitly deleted, which causes errors on /W1. While this is a pedantic warning (error), we can easily make the deletion explicit to avoid these warnings.

This CLs adds internally visible arena enabled constructors and copy constructors to ImplicitWeakMessage and WeakRepeatedPtrField.
PiperOrigin-RevId: 547544297
This change adds an arena enabled constructor guarded by `InternalVisibility`. It also moves the existing constructor inline as it's trivial, and implements the default constructor in terms of the (future private) arena constructor.
