internal/errors: initial commit

This adds package errors, which provides error handling constructs that are
specific to the protobuf repo. In particular, it provides a NonFatal type
which is useful for capturing non-fatal errors like invalid UTF-8 and required
fields not set.

High-level API:
	type NonFatalErrors []error
		func (NonFatalErrors) Error() string
	type NonFatal struct{ ... }
		func (*NonFatal) Merge(err error) (ok bool)
		func (*NonFatal) AppendInvalidUTF8(field string)
		func (*NonFatal) AppendRequiredNotSet(field string)
	func New(string, ...interface{}) error

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.
