all: refactor extensions, add proto.GetExtension etc.
...
Change protoiface.ExtensionDescV1 to implement protoreflect.ExtensionType.
ExtensionDescV1's Name field conflicts with the Descriptor Name method,
so change the protoreflect.{Message,Enum,Extension}Type types to no
longer implement the corresponding Descriptor interface. This also leads
to a clearer distinction between the two types.
Introduce a protoreflect.ExtensionTypeDescriptor type which bridges
between ExtensionType and ExtensionDescriptor.
Add extension accessor functions to the proto package:
proto.{Has,Clear,Get,Set}Extension. These functions take a
protoreflect.ExtensionType parameter, which allows writing the
same function call using either the old or new API:
proto.GetExtension(message, somepb.E_ExtensionFoo)
Fixes golang/protobuf#908

runtime/protoiface: move and rename XXX_Methods
...
This CL moves and renames the protoreflect.ProtoMessage.XXX_Methods
to protoreflect.Message.ProtoMethods.
Since one needs to obtain a protoreflect.Message now to get at
the fast-path methods, we modify the method signatures to take
in a protoreflect.Message instead of protoreflect.ProtoMessage.
Doing so also avoids the wrapper hack that was formerly done on
impl.messageReflectWrapper.
After this change the new protoc-gen-go no longer generates
any XXX fields or methods. All internal fields and methods are truly
hidden from the end-user.
