Generate everything related to extensions: extension descriptors,
XXX_InternalExtensions fields, etc.
Tweak the order in which we generate code for descriptors to ensure
consistent output with the previous protoc-gen-go.
Change Field.ContainingType to Field.ParentMessage, since we need to get
at the parent of both message fields and extensions (and the "containing
type" of an extension field is the extended message, under existing
terminology).

Include references to the proto, fmt, and math packages, consistent with
the ones in the previous generator:
// Reference imports to suppress errors if they are not otherwise used.
var _ = proto.Marshal
var _ = fmt.Errorf
var _ = math.Inf
Sort imports with ast.SortImports to ensure gofmt-compatible output.
Copy the protoc-gen-go/testdata/imports test files from
github.com/golang/protobuf.

Move generation of the init function that registers all the types in a
file into a single function.
Take some care to generate the registrations in the same order as the
previous protoc-gen-go, to make it easier to catch unintended
differences in output.
For the same reason, adjust the order of generation to generate all
enums before all messages (matches previous behavior).

Generate the proper map[key]value type for map fields.
Include the protobuf_key and protobuf_val field tags.
Do not generate the map entry structs.
Fix an initialization order bug in protogen: While proto files cannot
contain circular dependencies, a single file can contain dependency
cycles. First create types for all the descriptors in a file, then add
in references (currently just field->message and field->enum) in a
second pass.

Refactor fieldGoType to return the non-pointer type for scalar types
(i.e., "int", not "*int"), and a bool indicating whether the struct
field is a pointer to that type.
