We have an obscure bug where packed-by-default repeated custom options defined
in proto3 files are not correctly treated as packed when dynamic extensions are
used. This CL introduces a simple fix and adds a test verifying the correct
behavior.
The bug was not a major problem in most cases, since parsers will accept both
the packed and unpacked encodings. It is useful to fix this to ensure that
descriptors are serialized in a consistent way, though.

Fixes#12081.
The issue was the call to `MaybeDetachComment`: the conditional assumed that there was a next token, which was on the same line as the previous one, making attribution unclear. However, if there is no next token, we should not detach.
The actual fix is a one-liner. The rest of this PR is updates to the tests to verify this behavior under a handful of scenarios.
Closes#12082

By default all protos are included in proto instrumentation when inject_field_listener_events option is set. Adding proto instrumentation callbacks for every proto in the binary adds codesize and runtime performance penalties. This cl introduces 'protos_for_field_listener_events' option where a list of proto files can be provided (seperated by ':') for which field listener events will be injected.
For example :-
protos_for_field_listener_events=foo/bar/foo.proto:foo/bar.proto
The field listener event will only be sent for 'foo/bar/foo.proto' and 'foo/bar.proto'.

On some linkers, the ABI definitions in src/libprotoc.map and friends do not match all symbols that need to be exported. This causes a linker error when trying to use the resulting shared object library: `undefined reference to 'scc_info_FileDescriptorProto_google_2fprotobuf_2fdescriptor_2eproto'`
Quite a few people seem to be affected by this, see #5144 for discussion. It seems that yocto now applies this patch itself, but that doesn't help people building in other places (I encountered this on some HPC machines), so it would probably be good to apply it upstream as well.

After this change, the Rust codegen can be enabled via the protoc flag '--rust_out'. Due to its experimental nature we require a magic value to be provided '--rust_out=experimental-codegen=enabled:<out>'.
Make the 'RustGenerator' create an empty *.pb.rs file.

Custom `protoc` plugins may use this method to look up the framework name for a given file if they want to generate code not related to `import`s.

This documents Java's non-conformant behavior where closedness is determined by the field rather than the enum definition.

Proto2 fields with types corresponding to proto3 enums are treated as closed today, despite the EnumDescriptor reporting that they're open. This will allow syntax users to depend on this non-conformant behavior which will be getting it's own feature in Edition zero.

They now consistently parse the varint and then push the int32 representation into the unknown field set. Previously the behavior was sometimes pushing the original varint, sometimes pushing a uint32_t truncated value, and sometimes an int32_t truncated value.

This will make PRs from forked repositories significantly less painful, since they'll agree on which version of each action to use. OTOH, we'll have a separate repo that needs to be maintained, and changes to it will need to be coordinated and versioned carefully. This will likely need to be done less often though now that our infrastructure is stable.
