This is a breaking change in terms of proto2 code generation: users who were previously using these members will have to change to null checks for message fields.
After toying with removing Has/Clear for proto2 oneof fields, I've left them alone in this commit, for consistency with other languages. The inconsistency between proto2 and proto3 won't come up here, because proto3 oneof fields can never be explicitly optional.
Fixes#7395.

Fixes#7395.
- Bump the version marker in the generated code.
- Set the flag to say clear on zero is known.
- Set clear on zero for proto3 optional fields that aren't tagged as optional.
- Also tweak the call from some C generated code to use different apis with
better validation.
- Mark the ObjC generator as supporting the proto3 optional feature.
- Regenerate the WKTs to get the new flags.
- Don't make an OneofGenerator for synthetic oneofs.
- Update the field calculations that determine if hasbits are needed to
know about synthetic oneofs and ignore them.
FieldDescriptor::has_presence works as a replacement for the custom logic we
had for FieldGenerator::WantsHasProperty(), and is already proto3 optional
aware.
Most changes are:
- Introducing new helpers of SupportsPresenceApi and RequiresPresenceBit. This allows calling code to be a lot clearer about what it's interested in.
- Changing most previous IsProto2 calls to use one of the two new helper methods
- Avoiding treating synthetic oneofs as regular ones
- Some slight refactoring in csharp_primitive_field to avoid code duplication
- Comments explaining what we want when, so the next maintainer doesn't need to do the detective work I did!
This change deliberately doesn't modify the API surface of any
existing code. The only change to previously-generated C# should be
making presence bits more efficient in proto2.
Once proto3 optional fields are supported, we can consider further
changes to make the proto2 and proto3 generated API surface more
consistent (e.g. adding presence API for message fields and oneofs).
* WIP.
* WIP.
* Builds and runs. Tests need to be updated to test presence.
* Ruby: proto3 presence is passing all tests.
* Fixed a bug where empty messages has the wrong oneof count.
* Set execute bit on files if and only if they begin with (#!).
Git only tracks the 'x' (executable) bit on each file. Prior to this
CL, our files were a random mix of executable and non-executable.
This change imposes some order by making files executable if and only
if they have shebang (#!) lines at the beginning.
We don't have any executable binaries checked into the repo, so
we shouldn't need to worry about that case.
* Added fix_permissions.sh script to set +x iff a file begins with (#!).
This eliminates an ODR violation where users compile and install
Protobuf's C++ runtime without RTTI but do not define
GOOGLE_PROTOBUF_NO_RTTI when compiling their project with
the generated code.
JsonStreamParser::GetNextTokenType() uses HasPrefixString a lot on StringPiece as input. For each call two std::strings are constructed, compared and destroyed. Parsing of json-files with 50-60 MB in debug mode takes minutes.
* [bazel] Move Java runtime/toolchains into //java
This change moves `java_library` targets from the top-level BUILD file
into `//java/{core,lite,util}` and declares `alias` targets to point to
their new locations (hence, this is not a breaking change).
This will allow users that don't use Java to stop depending on
`@rules_java` (e.g. as requested in
https://github.com/bazelbuild/rules_scala/pull/989#issuecomment-583405161).
Note that there is no intention to deprecate + remove the top-level
targets in the foreseeable future.
* Add BUILD files in //java to java_EXTRA_DIST
