This PR removes the DSL from the code generator, in anticipation of splitting the DSL out into a separate package.
Given a .proto file like:
```proto
syntax = "proto3";
package pkg;
message TestMessage {
optional int32 i32 = 1;
optional TestMessage msg = 2;
}
```
Generated code before:
```ruby
# Generated by the protocol buffer compiler. DO NOT EDIT!
# source: protoc_explorer/main.proto
require 'google/protobuf'
Google::Protobuf::DescriptorPool.generated_pool.build do
add_file("test.proto", :syntax => :proto3) do
add_message "pkg.TestMessage" do
proto3_optional :i32, :int32, 1
proto3_optional :msg, :message, 2, "pkg.TestMessage"
end
end
end
module Pkg
TestMessage = ::Google::Protobuf::DescriptorPool.generated_pool.lookup("pkg.TestMessage").msgclass
end
```
Generated code after:
```ruby
# frozen_string_literal: true
# Generated by the protocol buffer compiler. DO NOT EDIT!
# source: test.proto
require 'google/protobuf'
descriptor_data = "\n\ntest.proto\x12\x03pkg\"S\n\x0bTestMessage\x12\x10\n\x03i32\x18\x01 \x01(\x05H\x00\x88\x01\x01\x12\"\n\x03msg\x18\x02 \x01(\x0b\x32\x10.pkg.TestMessageH\x01\x88\x01\x01\x42\x06\n\x04_i32B\x06\n\x04_msgb\x06proto3"
begin
Google::Protobuf::DescriptorPool.generated_pool.add_serialized_file(descriptor_data)
rescue TypeError => e
# <compatibility code, see below>
end
module Pkg
TestMessage = ::Google::Protobuf::DescriptorPool.generated_pool.lookup("pkg.TestMessage").msgclass
end
```
This change fixes nearly all remaining conformance problems that existed previously. This is a side effect of moving from the DSL (which is lossy) to a serialized descriptor (which preserves all information).
## Backward Compatibility
This change should be 100% compatible with Ruby Protobuf >= 3.18.0, released in Sept 2021. Additionally, it should be compatible with all existing users and deployments. However there is some special compatibility code I inserted to achieve this level of backward compatibility.
Without the compatibility code, there is an edge case that could break backward compatibility. The existing code is lax in a way that the new code would be more strict.
When we use a full serialized descriptor, it will contain a list of all `.proto` files imported by this file (whereas the DSL never added dependencies properly): dfb71558a2/src/google/protobuf/descriptor.proto (L65-L66)
`add_serialized_file` will verify that all dependencies listed in the descriptor were previously added with `add_serialized_file`. Generally that should be fine, because the generated code will contain Ruby `require` statements for all dependencies, and the descriptor will fail to load anyway if the types we depend on were not previously defined in the DescriptorPool.
But there is a potential for problems if there are ambiguities around file paths. For example, consider the following scenario:
```proto
// foo/bar.proto
syntax = "proto2";
message Bar {}
```
```proto
// foo/baz.proto
syntax = "proto2";
import "bar.proto";
message Baz {
optional Bar bar = 1;
}
```
If you invoke `protoc` like so, it will work correctly:
```
$ protoc --ruby_out=. -Ifoo foo/bar.proto foo/baz.proto
$ RUBYLIB=. ruby baz_pb.rb
```
However if you invoke `protoc` like so, and didn't have any compatibility code, it would fail to load:
```
$ protoc --ruby_out=. -I. -Ifoo foo/baz.proto
$ protoc --ruby_out=. -I. -Ifoo foo/bar.proto
$ RUBYLIB=foo ruby foo/baz_pb.rb
foo/baz_pb.rb:10:in `add_serialized_file': Unable to build file to DescriptorPool: Depends on file 'bar.proto', but it has not been loaded (Google::Protobuf::TypeError)
from foo/baz_pb.rb:10:in `<main>'
```
The problem is that `bar.proto` is being referred to by two different canonical names: `bar.proto` and `foo/bar.proto`. This is a user error: each import should always be referred to by a consistent full path. Hopefully user errors of this sort are rare, but it is hard to know without trying.
The code in this PR prints a warning using `warn` if we detect that this edge case has occurred. We will plan to remove this compatibility code in the next major version.

Syntax will become meaningless once we migrate to editions. In the meantime, we've implemented APIs to expose the differences between proto2 and proto3 in terms of the features we plan to release in edition 2023.

When generating Ruby clients for proto3 messages that have a oneof, we generate a hazzer for members of the oneof, not just a hazzer for the oneof itself.
In other words, for a proto like this:
```
syntax = "proto3";
message Foo {
oneof bar {
string baz = 1;
}
}
```
The generated `Foo` will now have a method called `has_baz?`, in addition to the (pre-existing) method `has_bar?`.
I updated the unit tests, and verified that all the tests under `//ruby/...` pass.
Fixes https://github.com/protocolbuffers/protobuf/issues/9561.

This uses https://github.com/protocolbuffers/rules_ruby to fully Bazelify our ruby runtime code. The Rakefile is left in place for now and is still used by our aarch64 tests. With the current implementation ruby behaves similarly to our python wrapper, which selects whatever version is installed in the system. Future enhancements will allow for more hermetic builds via Bazel flags to pin a specific version

All synthetic methods implemented by `method_missing` are now supported by `respond_to?`.
Fixes issue #9202.
* Fix null pointer exceptions exposed by new regression tests.
* Fix clear_ on oneofs so that it is safe to call repeatedly and so that respond_to? does not depend on whether the oneof is currently cleared.
* Code cleanup: reenable more tests on JRuby.
* Align JRuby behavior with CRuby by throwing a RuntimeError when attempting to assign to a oneof.

* Message.decode/encode: Add max_recursion_depth option
This allows increasing the recursing depth from the default of 64, by
setting the "max_recursion_depth" to the desired integer value. This is
useful to encode or decode complex nested protobuf messages that otherwise
error out with a RuntimeError or "Error occurred during parsing".
Fixes#1493
* Address review comments

`System.identityHashCode` returns a hash that does not consider a
Message's values. This means two Messages with identical values will not
have identical hashCodes.
This patch uses the pattern from RubyMap to combine the hashCodes from
all values in a given message and produce a unique, consistent,
value-based hash.

* make consistent between mri and jruby
* create a #to_h and have it use symbols for keys
* add #to_json and #to_proto helpers on the Google::Protobuf message classes
