Damien Neil 4686e239b6 proto: add IsInitialized 
Move all checks for required fields into a proto.IsInitialized function.

Initial testing makes me confident that we can provide a fast-path
implementation of IsInitialized which will perform more than
acceptably.  (In the degenerate-but-common case where a message
transitively contains no required fields, this check can be nearly
zero cost.)

Unifying checks into a single function provides consistent behavior
between the wire, text, and json codecs.

Performing the check after decoding eliminates the wire decoder bug
where a split message is incorrectly seen as missing required fields.

Performing the check after decoding also provides consistent and
arguably more correct behavior when the target message was partially
prepopulated.

Next Generation Go Protocol Buffers

WARNING: This repository is in active development. There are no guarantees about API stability. Breaking changes will occur until a stable release is made and announced.

This repository is for the development of the next major Go implementation of protocol buffers. This library makes breaking API changes relative to the existing Go protobuf library. Of particular note, this API aims to make protobuf reflection a first-class feature of the API and implements the protobuf ecosystem in terms of reflection.
