Introduce the EmitDefaultValues in addition to the existing
EmitUnpopulated option.
EmitDefaultValues is added to emit json messages more compatible with
the `always_print_primitive_fields` option of the cpp protobuf library.
EmitUnpopulated overrides EmitDefaultValues since the former generates
a strict superset of the latter.

The purpose of struct.proto is to be an exact mapping of JSON in protobufs.
Since JSON doesn't support NaN and Inf, we should reject serialization
of such values. Prior to this CL, they would be serialzed as a JSON string,
which would change the interpretation of the value when round-tripped.

This is step 2 of 6 in a multi-stage migration
to move the well-known types
from the google.golang.org/genproto module
to the google.golang.org/protobuf module.
The generated Go packages for field_mask.proto, api.proto,
type.proto, and source_context.proto are being moved over
to this module alongside all the other well-known types.
In order to move these types between two modules,
there needs to be a sequence of changes submitted in
decently rapid succession. It is impossible to atomically
make these changes, so a brief breakage is inevitable.
The steps are as follows:
Step 1: Submit a change to cloud.google.com/go/internal/gapicgen
to avoid generating the well-known types. Otherwise, the tool
will undo the changes made in step 3.
See https://code-review.googlesource.com/c/gocloud/+/56810
Step 2: Submit a change to google.golang.org/protobuf that
adds the generated well-known types being migrated to that module.
In order to prevent the situation where a user links in
too old a version of the genproto module such that
duplicate registration occurs for the well-known types,
the registry is specially modified to provide an error
message that instructs users to upgrade the genproto module.
See https://golang.org/cl/234937
Step 3: Submit a change to google.golang.org/genproto that
switches all generated well-known types to be aliases to the
ones declared in google.golang.org/protobuf from the previous step.
This will cause the genproto module to incur an dependency
on an unreleased version of the protobuf module.
See https://github.com/googleapis/go-genproto/pull/372
Step 4: Submit a change to google.golang.org/protobuf that
adds a weak module depdency on the genproto module at the
revision from the previous step.
Step 5: Release google.golang.org/protobuf@v1.24.0.
Step 6: Submit a change to google.golang.org/genproto that
updates the protobuf module dependency to v1.24.0.

Immediately abort (un)marshal operations when encountering invalid UTF-8
data in proto3 strings. No other proto implementation supports non-UTF-8
data in proto3 strings (and many reject it in proto2 strings as well).
Producing invalid output is an interoperability threat (other
implementations won't be able to read it).
The case where existing string data is found to contain non-UTF8 data is
better handled by changing the field to the `bytes` type, which (aside
from UTF-8 validation) is wire-compatible with `string`.
Remove the errors.NonFatal type, since there are no remaining cases
where it is needed. "Non-fatal" errors which produce results and a
non-nil error are problematic because they compose poorly; the better
approach is to take an option like AllowPartial indicating which
conditions to check for.

The wire representation of the contents of an Any is a `bytes` field
containing the the wire encoding of the contained message. The in-memory
representation is just these bytes.
The wire (un)marshaler has no special handling for Any values, and
happily accepts whatever bytes are present.
The text and JSON marshalers will unmarshal the bytes in an Any,
and the unmarshalers will marshal the Any to produce the in-memory
representation. This makes them stricter than the wire (un)marshaler:
Marshaling an Any which contains invalid data to text/JSON fails, while
marshaling it to wire format does not. This does make some sense, since
the Any already contains wire-format data; validation is performed at an
earlier time when producing that data.
This change brings the text and JSON (un)marshal functions a bit more
into alignment with the wire format by never performing checks for
required fields on the contents of an Any.
This has the advantage of consistently performing checks for required
fields exactly once per marshal/unmarshal operation, and over the same
data no matter which encoding is used. It also eliminates the one case
where a required field check is considered "non-fatal", generating an
error but not terminating the (un)marshal operation.

Added API:

Message.Get

Message.Mutable
Message.NewMessage
Message.WhichOneof
Message.GetUnknown
Message.SetUnknown
Deprecated API (to be removed in subsequent CL):
Message.KnownFields
Message.UnknownFields
The primary difference with the new API is that the top-level
Message methods are keyed by FieldDescriptor rather than FieldNumber
with the following semantics:
* For known fields, the FieldDescriptor must exactly match the
field descriptor known by the message.
* For extension fields, the FieldDescriptor must implement ExtensionType,
where ContainingMessage.FullName matches the message name, and
the field number is within the message's extension range.
When setting an extension field, it automatically stores
the extension type information.
* Extension fields are always considered nullable,
implying that repeated extension fields are nullable.
That is, you can distinguish between a unpopulated list and an empty list.
* Message.Get always returns a valid Value even if unpopulated.
The behavior is already well-defined for scalars, but for unpopulated
composite types, it now returns an empty read-only version of it.
