internal/{fileinit,impl}: minimal weak field support Weak fields are an obsolete proto1 feature. They have been superseded by extensions. However, some vestigial support for weak fields does remain, mostly as Google-internal patches. (They aren't exciting; extensions really do everything weak fields do in a cleaner and more portable fashion.) At the moment, the only visible impact of marking a field [weak=true] is to exclude it from "internal/fileinit".FileBuilder.DependencyIndexes. We want to preserve that behavior just in case we ever do add full weak field support here. Extend fileinit to look up message descriptors for weak fields in the global registry. If the descriptor cannot be found, use a placeholder instead. Remove special-case handling of weak fields in the impl package. The code generator doesn't do anything special for them, so they can be treated as any other field.

encoding: support weak fields in text and JSON unmarshaling If the message for a weak field is linked in, we treat it as if it were identical to a normal known field. However, if the weak field is not linked in, we treat it as if the field were not known.

all: implement proto1 weak fields This implements generation of and reflection support for weak fields. Weak fields are a proto1 feature where the "weak" option can be specified on a singular message field. A weak reference results in generated code that does not directly link in the dependency containing the weak message. Weak field support is not added to any of the serialization logic.
