Joshua Haberman	115b878a5c	Optimization: do not generate oneofs for proto3 optional fields. Proto3 optional fields should use a hasbit for their presence. But we had been giving them oneof layouts, which makes them unnecessarily large. This CL will shrink messages with proto3 optional fields, by using hasbits instead of oneof cases for them.

Eric Salo	6f68ba1350	upb: fail if a message set contains any sub-fields This was causing fuzzer test failures. Unrelated: inlined a few calls to upb_MessageDef_FullName() for performance PiperOrigin-RevId: 483389910	2 years ago

Joshua Haberman	b33fd88ed3	Added function for getting the type of a MiniTable field Prior to this CL, users were relying on `field->descriptortype` to get the field type. This almost works, as `field->descriptortype` is almost, but not quite, the field type of the field. In two special cases we deviate from the true field type, for ease of parsing and serialization: - For open enums, we use `kUpb_FieldType_Int32` instead of `kUpb_FieldType_Enum`, because from the perspective of the wire format, an open enum field is equivalent to int32. - For proto2 strings, we use `kUpb_FieldType_Bytes` instead of `kUpb_FieldType_String`, because proto2 strings do not perform UTF-8 validation, which makes them equivalent to bytes. In this CL we add a public API function: ``` // Returns the true field type for this field. upb_FieldType upb_MiniTableField_Type(const upb_MiniTable_Field* f); ``` This will provide the actual field type for this field. Note that this CL changes the MiniDescriptor format. Previously MiniDescriptors did not contain enough information to distinguish between Enum/Int32. To remedy this we added a new encoded field type, `kUpb_EncodedType_ClosedEnum`. PiperOrigin-RevId: 479387672	2 years ago
Eric Salo	44916d7d27	create reflection_internal library internal declarations are now physically removed from the public headers PiperOrigin-RevId: 478921131	2 years ago
Eric Salo	b8bec58e01	pull the mini descriptor encoders into their proper .c files Performance neutral but it simplifies the code, shrinks the public surface, and makes logical sense PiperOrigin-RevId: 478038589	2 years ago
Eric Salo	1e3deb013d	move message/field modifiers functions out of mini_descriptor_encode.c PiperOrigin-RevId: 477486367	2 years ago
Eric Salo	efd06e46a4	use mini descriptors to build message defs and extension defs PiperOrigin-RevId: 477332937	2 years ago
Eric Salo	00765002ff	- All of reflection now lives in upb/reflection/ - Each def type has its own .c file and its own .h file - Functions that require a builder context are declared in def_builder.h - The mini descriptor encoders have also been pulled into upb/reflection/ - upb/def.h, upb/def.hpp, upb/reflection.h, and upb/reflection.hpp are now deprecated stubs that point to the new headers PiperOrigin-RevId: 474459500	2 years ago
