The conditional was accidentally inverted.
This function provides dubious support for encoding/json.

Fix a reversed error check in impl.Export{}.WeakNil.
Check to see if we have a type for the weak field on marshal/size.
Treat a typed nil valued in XXX_Weak as not indicating presence for
the field.

This change:
* Adds aberrant support for the undocumented XXX_MessageName method.
* Adds LegacyMessageTypeOf so that v1 registration can suggest a
fullname to use with a legacy message with no Descriptor support.

In order to migrate v1 to wrap v2, we need a way to reproduce
the awful enum "names" that v1 used, which was the concatenation of
the proto package with the Go identifier used for the enum.
To support this:
* Move the camel case logic from compiler/protogen to internal/strs
* Add a small stub in internal/impl to expose this functionality

This implements generation of and reflection support for weak fields.
Weak fields are a proto1 feature where the "weak" option can be specified
on a singular message field. A weak reference results in generated code
that does not directly link in the dependency containing the weak message.
Weak field support is not added to any of the serialization logic.

The v2 implementation will eagerly unmarshal extension fields,
which means that the logic to synchronize the extensions fields
is no longer necessary. Using type aliases, we can ensure
impl.ExtensionsV1 is identical to the extensions map prior to
a4ab9ec5 from May 2016. This makes it such that we only have one
legacy implementation that we have to deal with.

As a goal, v2 should not depend on v1. As another step towards that end,
we move all the types that used to be in the v1 protoapi package over to v2.
For now, we place MessageV1, ExtensionRangeV1, and ExtensionDescV1
in runtime/protoiface since these are types that generated messages will
probably have to reference forever. An alternative location could be
reflect/protoreflect, but it seems unfortunate to have to dirty the
namespace of that package with these types.
We move ExtensionFieldV1, ExtensionFieldsV1, and ExtensionFieldsOf
to internal/impl, since these are related to the implementation of a
generated message.
Since moving these types from v1 to v2 implies that the v1 protoapi
package is useless, we update all usages of v1 protoapi in the v2
repository to point to the relevant v2 type or functionality.
CL/168538 is the corresponding change to alter v1.
There will be a temporary build failure as it is not possible
to submit CL/168519 and CL/168538 atomically.

The EnumName, UnmarshalJSONEnum, and CompressGZIP helpers currently live
in v1 protoapi, which would cause all generated messages to depend on v1.
In an effort to break the dependency of v2 on v1, we move these helper
functions to v2 (and re-written to take advantage of protobuf reflection).
These helpers are unfortunate, but we cannot eliminate the functionality
that they implement since they are exposed in the publicly generated API.
Since EnumName does not rely on the enum maps, it removes another dependency
on those variables. Eventually, we can get to the point where these variables
(though declared) are not linked into the binary if the user does not use them.
Also, we rely on the v1 proto package for registration instead of v1 protoapi.
This may re-introduce a cyclic dependency on descriptor proto again in the
future, but the better approach is to just start registering with v2.
