09b28a97f7 encoding/textpb: clean-up code and fix error handling inside closures
In marshalMap, replace Map.Range and sortMap with
internal/mapsort.Range. Also, make sure to capture fatal error properly
for return.

In appendExtensions, capture fatal error properly for return. Added a
testcase that shows this was a bug.

In unmarshalAny, remove unnecessary checks and use internal/fieldnum for
Any's field numbers.

So far only Ints is being used and it does not seem like the
other set types will ever be used. Remove them.
We can always add them back if we need them again.

0d3e8cc096 proto, runtime/protoiface: add support for fast-path marshaling
Allow message implementations to provide optimized versions of standard
operations. Generated messages now include a ProtoReflectMethods method,
returning a protoiface.Methods struct containing pointers to assorted
optional functions.

The Methods struct also includes a Flags field indicating support for
optional features such as deterministic marshaling.

Implementation of the fast paths (and tests) will come in later CLs.

Discussion at https://github.com/protocolbuffers/protobuf/issues/5390.

As of this CL, code currently handles marshaling of Empty embedded
in Any, but not unmarshaling of Any yet. I'd like to get this corrected
first in order to proceed with unmarshaling of Any.

* internal/fileinit.FileBuilder.MessageOutputTypes is switched from
protoreflect.MessageType to protoimpl.MessageType since the
implementation must be fully inialized before registration occurs.
* The test for internal/legacy/file_test.go is switched to a legacy_test
package to avoid a cyclic dependency.

inside Value as well. Only produce numberParts for calls to
Value.{Int,Uint} call.

numberParts is only used for producing integers and removing the logic to
produce numberParts improves overall decoding speed for floats, and shows no

4fddebafc0 all: move v1 types over to the v2 repository
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.

4532dd7969 internal/fileinit: prevent map entry descriptors from implementing MessageType
The protobuf type system hacks the representation of map entries into that
of a pseudo-message descriptor.

Previously, we made all message descriptors implement MessageType
where type descriptors had a GoType method that simply returned nil.
Unfortunately, this violates a nice property in the Go type system
where being able to assert to a MessageType guarantees that Go type
information is truly associated with that descriptor.

This CL makes it such that message descriptors for map entries
do not implement MessageType.

f31bf2612e cmd/protoc-gen-go: only depend on v2 proto package
This CL breaks another dependency of v2 on v1.
A missing feature in v2 is proto.Clone, but we can use a
Marshal/Unmarshal roundtrip to achieve the same effect
as a temporary stop-gap.

8e506a8704 cmd/protoc-gen-go: rely on protoimpl for basic helpers
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.

e0cf15babe encoding/textpb: fix failed tests due to ordering of marshaled binary fields
Added temporary work-around for now by always using deterninistic
marshaling so that protoV1.Equals knows how to do comparison.

Substitute protoV1.Marshal calls to use proto v2.

A few tests still need to use v1 due to missing required field checks in

c96a79da29 encoding/jsonpb: add support for basic unmarshaling
Unmarshaling of scalar, messages, repeated, and maps.

Need to further improve on error messages for consistency, some error
messages contain the position info while some currently do not.  There
are cases where position info is wrong as well when a value is decoded
in another pass, e.g. numbers in string value, or map keys.

afb455eaf8 cmd/protoc-gen-go: correlate v1 ExtensionDesc with v2 ExtensionType
Unfortunately a good amount of code uses pointer comparisons on the
v1 ExtensionDesc to determine exactly which extension field is set,
rather than checking whether the extension descriptor semantically
describes the field that they are interested in.

To preserve this behavior in v1, we need a 1:1 mapping between
a v2 ExtensionType and a specific v1 ExtensionDesc.

990b9f5919 internal/prototype: move from reflect/prototype
The prototype package was initially used by generated reflection support,
but has now been replaced by internal/fileinit.
Eventually, this functionality should be deleted and re-written in terms
of other components in the repo.

Usages that prototype currently provides (but should be moved) are:
* Constructing standalone messages and enums, which is behavior we should
provide in reflect/protodesc. The google.protobuf.{Enum,Type} are well-known
proto messages designed for this purpose.
* Constructing placeholder files, enums, and messages.
* Consructing protoreflect.{Message,Enum,Extension}Types, which are protobuf
descriptors with associated Go type information.
