The only public target here is the edition defaults helper macro, which can be used by external runtimes and plugins. None of this code is C++-specific though, and should be organized higher up. Appropriate aliases are also placed at the top level for public targets

Every language has very different handling of utf8 validation. Any with proto2/proto3 differences will receive language-specific features for edition zero to better model these subtle differences.

This helps make the API more complete, since the FeatureSet object will always be fully resolved on any accessible features. This specifically targets C++ plugins though, which will now have their features filled in by default. Before, any proto files that didn't include the language-specific features would result in unresolved extensions in the generators.

This replaces the cc_utf8_verification and enforce_utf8 options with the corresponding feature values, consistent with C++ behavior. Further runtimes will be supported by refactoring the string_field_validation feature in a later change.

Before this CL all messages were generated in the top-level crate module. With
this change we generate messages under the module specified by the package
declaration in the .proto file.
Dots are interpreted as submodule separator in consistency with how C++
namespaces are handled.
Note that name of the proto_library target still remains to be used as the crate name. This CL only adds crate submodules dependeing on the specified package.

This turns out to be quite of a yak shave to be able to perfectly test both kernels without having to pass extra Blaze flags.

In this CL we're adding the barebones infrastructure to generate Rust proto messages using UPB as a backend. The API is what we call a V0, not yet production-quality, not yet rigorously designed, just something to enable parallel work.
The interesting part of switching backend between UPB and C++ will come in a followup.

The internal design is consistent with other <lang>_proto_library rules. rust_proto_library attaches rust_proto_library_aspect on its `deps` attribute. The aspect traverses the dependency, and when it visits proto_library (detected by ProtoInfo provider) it registers 2 actions:
1) to run protoc with Rust backend to emit gencode
2) to compile the gencode using Rustc
Action (2) gets the Rust proto runtime as an input as well.
Coming in a followup is support and test coverage for proto_library.deps.

This pull request includes two implementation: C extension and PHP
package. Both implementations support encode/decode of singular,
repeated and map fields.
General
* License changed from Apache 2.0 to New BSD.
* It is now possible to define custom "options", which are basically
annotations which may be placed on definitions in a .proto file.
For example, you might define a field option called "foo" like so:
import "google/protobuf/descriptor.proto"
extend google.protobuf.FieldOptions {
optional string foo = 12345;
}
Then you annotate a field using the "foo" option:
message MyMessage {
optional int32 some_field = 1 [(foo) = "bar"]
}
The value of this option is then visible via the message's
Descriptor:
const FieldDescriptor* field =
MyMessage::descriptor()->FindFieldByName("some_field");
assert(field->options().GetExtension(foo) == "bar");
This feature has been implemented and tested in C++ and Java.
Other languages may or may not need to do extra work to support
custom options, depending on how they construct descriptors.
C++
* Fixed some GCC warnings that only occur when using -pedantic.
* Improved static initialization code, making ordering more
predictable among other things.
* TextFormat will no longer accept messages which contain multiple
instances of a singular field. Previously, the latter instance
would overwrite the former.
* Now works on systems that don't have hash_map.
Python
* Strings now use the "unicode" type rather than the "str" type.
String fields may still be assigned ASCII "str" values; they will
automatically be converted.
* Adding a property to an object representing a repeated field now
raises an exception. For example:
# No longer works (and never should have).
message.some_repeated_field.foo = 1
