The v1 generator doesn't include a "proto3" tag on extension fields,
even when the field is defined in a proto3 file. Match that behavior for
consistency. We can probably change this later if we want to; it's
unlikely anyone is depending on this behavior.
The v1 generator uses pointer types for extension fields, even when the
field is defined in a proto3 file. (e.g., *FooEnum instead of FooEnum.)
Match this behavior. We can't change this without breaking compatibility
in the generated code.

Add special-case handling for extension fields named
"message_set_extension" that extend a message_set_wire_format message.
Support special cases for a proto1 feature that was superseded by proto2
extensions.

This change was created by running:
git ls-files | xargs sed -i "s|google.golang.org/proto|github.com/golang/protobuf/v2|g"
This change is *not* an endorsement of "github.com/golang/protobuf/v2" as the
final import path when the v2 API is eventually released as stable.
We continue to reserve the right to make breaking changes as we see fit.
This change enables us to host the v2 API on a repository that is go-gettable
(since go.googlesource.com is not a known host by the "go get" tool;
and google.golang.org/proto was just a stub URL that is not currently served).
Thus, we can start work on a forked version of the v1 API that explores
what it would take to implement v1 in terms of v2 in a backwards compatible way.

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).
