The Value and MayKey types are defined in value.go, but the methods on
these types are defined in value_union.go. It's not immediately clear
to the reader of the code that these types have methods, or where they
are defined.
Move the type definitions to value_union.go to keep the entire type in a
single place.

Implement Format methods to provide the ability to pretty-print the descriptor
in a humanly readable fashion. While this functionality is not strictly necessary
for the operation of Go protobuf, it is a useful aid for humans.

Implement NewFileFromDescriptorProto, which constructs a
protoreflect.FileDescriptor from a provided descriptor.FileDescriptorProto.
Some other minor changes:
* Allow calling Find and Range methods on nil *protoregistry.Files to match
the behavior of maps where index operations are permitted, but store panics.
* Switch protoregistry test to be protoregistry_test to avoid cyclic dependency.

The prototype package provides constructors to create protobuf types that
implement the interfaces defined in the protoreflect package.
High-level API:
func NewFile(t *File) (protoreflect.FileDescriptor, error)
type File struct{ ... }
type Message struct{ ... }
type Field struct{ ... }
type Oneof struct{ ... }
type Enum struct{ ... }
type EnumValue struct{ ... }
type Extension struct{ ... }
type Service struct{ ... }
type Method struct{ ... }
func NewEnum(t *StandaloneEnum) (protoreflect.EnumDescriptor, error)
func NewMessage(t *StandaloneMessage) (protoreflect.MessageDescriptor, error)
func NewExtension(t *StandaloneExtension) (protoreflect.ExtensionDescriptor, error)
type StandaloneEnum struct{ ... }
type StandaloneMessage struct{ ... }
type StandaloneExtension struct{ ... }
func PlaceholderFile(path string, pkg protoreflect.FullName) protoreflect.FileDescriptor
func PlaceholderEnum(name protoreflect.FullName) protoreflect.EnumDescriptor
func PlaceholderMessage(name protoreflect.FullName) protoreflect.MessageDescriptor
This CL is missing some features that are to be added later:
* The stringer methods are not implemented, providing no way to print the
descriptors in a humanly readable manner.
* There is no support for proto options or retrieving the raw descriptor.
* There are constructors for Go specific types (e.g., protoreflect.MessageType).
We drop go1.9 support since we use strings.Builder.
We switch to go.11rc1 to obtain some bug fixes for modules.
