§Reflection implementation for protobuf data

rust-protobuf supports reflection for both:

generated messages (generated rust code)
dynamic messages (created from arbitrary FileDescriptorProto without code generation)

The API to work with these types of messages is the same.

The API roughly follows Google protobuf C++ and Java API. Some minor adjustements are made to make code more idiomatic to rust.

EnumDescriptor: Dynamic representation of enum type.
EnumValueDescriptor: Description for enum variant.
FieldDescriptor: Field descriptor.
FileDescriptor: Reflection for objects defined in .proto file (messages, enums, etc).
MessageDescriptor: Dynamic representation of message type.
MessageRef: Wrapper around either MessageFull reference or a container for an empty dynamic message.
MethodDescriptor: Service method descriptor.
OneofDescriptor: Oneof descriptor.
ReflectEqMode: Parameter for ReflectEq.
ReflectMapMut: Dynamic mutable reference to map field
ReflectMapRef: Dynamic reference to map field
ReflectOptionalRef: Singular field field and value type.
ReflectRepeatedMut: Dynamic mutable reference to repeated field
ReflectRepeatedRef: Dynamic reference to repeated field
ServiceDescriptor: Dynamic representation of service type.

ReflectFieldRef: Reference to a value stored in a field, optional, repeated or map.
ReflectValueBox: Owner value of any elementary type
ReflectValueRef: A reference to a value
RuntimeFieldType: Reflective representation of field type.
RuntimeType: Runtime representation of elementary protobuf type.
Syntax: .proto file syntax.

ProtobufValue: Type implemented by all protobuf singular types (primitives, string, messages, enums).
ReflectEq: Special version of eq.
