This change required updating editions_defaults.binpb with
--edition_defaults_maximum=2024 so that we can use edition 2024 in our
testdata/enumprefix.proto test file.
For end users, this feature will only be available once:
1. protoc declares support for edition 2024 (expected early 2025).
2. protoc-gen-go declares support for edition 2024.

All of the other features, including custom features for C++ and Java,
allow setting a file-wide default. This makes it easier to migrate
proto2 files, so that the feature can be set at the file level instead
of needing to manually annotate each enum element. This adds the same
convenience to the (pb.go).legacy_unmarshal_json_enum feature that is
defined in this repo.

Resolvesgolang/protobuf#1615
The protoc compiler disallows setting the message encoding feature of
map fields to delimited since maps, at least for now (as of edition
2023) should always use normal length-prefixed encoding.
But the field (and a message value field inside the map entry) could
inherit such a feature value if it were set as a file-wide default. At
the point where the code changes the kind from message to group, based
on the field's resolved features, the message type hasn't yet been
resolved. So this change adds a check after the FieldDescriptor's
message type is resolved, to change the kind back from group to
message if the field is a map field or a field in a map entry message.

When I implemented this initially, I thought the parent of an extension is the
extendee. This is incorrect. The parent is the scope in which the extension is
defined. This CL changes the code to use the correct parent. This also allows
us to reduce some complexity in the implementation because we don't need to
wait until the extendee is resolved before we can resolve the features.

This updates all generated code to match the contents of the latest
v22.0 release of Protobuf.
This involved a couple of changes to the script that does the sync'ing:
1. The new Protobuf version no longer includes autoconf configuration
and instead requires using bazel to build things.
2. The new Protobuf release does not have an artifact named
"protobuf-all-${VERSION}.tar.gz", but the one named
"protobuf-${VERSION}.tar.gz" has all of the sources and was
sufficient for the regenerate.bash script to complete.
This change does NOT regenerate the protos related to benchmarks.
The Protobuf repo no longer includes benchmarks. The CL removing them
says they are superceded by google/fleetbench:
83c499de86
But that project's proto benchmark files are very different:
https://github.com/google/fleetbench/tree/main/fleetbench/proto
So I commented out those steps in the generation code since the benchmarks
will need some work to reconcile with fleetbench.
This code adds known failing tests for conformance. New test cases were
added in https://github.com/protocolbuffers/protobuf/pull/9534, but the
Go protojson package does not behave according to the new tests. There
is an existing issue in GitHub about this:

The Go generator has historically always prefixed an enum value
with the name of the enum type, when it was unnecessary to do so.
For example:
enum Status {
STATUS_FAILED = 0;
STATUS_PASSED = 1;
}
would be generated as:
type Status int32
const (
Status_STATUS_FAILED Status = 0
Status_STATUS_PASSED Status = 1
)
It is common for the enum values to be manually prefixed by the
enum type since protobuf enums use C++ namespace rules where
enum types and enum values are in the same namespace scope.
Thus, having the Go generator add a prefix is redundant.
See https://github.com/golang/protobuf/issues/513.
Some custom Go generators like protoc-gen-gogo allow removing
the prefix with the gogoproto.goproto_enum_prefix feature.
However, this leads to interoperability issues between
protoc-gen-go and protoc-gen-gogo, where the enum value names
cannot be accurately inferred.
Avoid this problem by just hard-coding the enum value number
for values declared in other packages. This provides benefits
in interoperability at the small cost of enum values possibly
being stale if their value were ever changed in a remote package.
However, this would only occur with use of proto2 enums and
default values, which seems to be an exceptionally rare situation.
Before:
Default_MyMessage_MyField = remotepb.FooEnum_FOO_ENUM
After:
Default_MyMessage_MyField = remotepb.FooEnum(4) // remotepb.FooEnum_FOO_ENUM
Before:
func (x *MyMessage) GetField() remotepb.FooEnum {
...
return remotepb.FooEnum_FOO_ZERO
}
After:
func (x *MyMessage) GetField() remotepb.FooEnum {
...
return remotepb.FooEnum(0) // always 0 for proto3 and often 0 for proto2
}

The ExtensionRangeArray was a pseudo-internal API that was used by
the protobuf runtime implementation to know what the extension ranges are.
For some time now, the runtime implementation does not make use of this.
According to all the latest modules known by the module proxy,
no code depends directly on this method being present.
In the extremely rare case where some user code is depending on this method,
the user can place a .go file next to the generated .pb.go file that
injects this method.

Change protoV1.ExtensionDesc to directly implement ExtensionType
rather than delegating to one.
Unify the previous types protoiface.ExtensionDescV1 and
filetype.Extension in impl.ExtensionInfo. The protoV1.ExtensionDesc
type becomes an alias to ExtensionInfo.
This gives us:
- Just one implementation of ExtensionType.
- Generated foopb.E_Ext vars are canonical ExtensionTypes.
- Generated foopb.E_Ext vars are also v1.ExtensionDescs for backwards
compatibility.
- Conversion between legacy and modern representations happens
transparently when lazily initializing an ExtensionInfo.
Overall, a simplification for users of generated code, since they can
mostly ignore the ExtensionDesc/ExtentionType distinction and use the
same value in either the old or new API.

In order for protoc-gen-go to output the current version,
it needs to know what version it is currently running as.
However, we cannot rely on the git tags since the tags are not
made until *after* the commit has been submitted.
Instead, we manually encode the version into the code and
make sure that git tags match up with the version in the code.
The version.go file in runtime/protoimpl contains instructions
for how to make a release. Essentially:
* Every non-release commit has a version string with "devel" in it.
* Every release commit must not have "devel" in it and must be unique.
* The "release process" involves submitting two CLs.
The first CL creates a version string without "devel",
which is the commit that a git tag will actually reference.
The second CL follows immediately and re-introduces "devel"
into the version string.
The following example shows a possible sequence of VersionStrings
for git commits in time-ascending order:
v1.19.0-devel (this CL)
v1.19.0-devel
v1.19.0-devel
v1.19.0-devel
v1.20.0-rc.1 <- tagged
v1.20.0-rc.1.devel
v1.20.0-rc.1.devel
v1.20.0-rc.1.devel
v1.20.0-rc.2 <- tagged
v1.20.0-rc.2.devel
v1.20.0 <- tagged (future public release)
v1.20.0-devel
v1.20.0-devel
v1.20.0-devel
v1.20.0-devel
v1.20.1 <- tagged
v1.20.1-devel
v1.20.1-devel
v1.21.0 <- tagged
v1.21.0-devel
Note that we start today with v1.19.0-devel, which means that our initial
release will be v1.20.0. This number was intentionally chosen since
1) the number 20 has some correlation to the fact that we keep calling
the new implementation the "v2" implementation, and
2) the set of tagged versions for github.com/golang/protobuf
and google.golang.org/protobuf are unlikely to ever overlap.
This way, the version of protoc-gen-go is never ambiguous which module
it was built from.
Now that we have version information, we add support for generating .pb.go
files with the version information recorded. However, we do not emit
these for .pb.go files in our own repository since they are always guaranteed
to be at the right version (enforced by integration_test.go).
