Josh Haberman e9d79d2441 Added upb::FileDef, which represents the file defs are declared in. It is entirely optional: MessageDef/EnumDef can still exist on their own. But this can represent a def's file when it is desirable to do so (eg. for code generators). This approach will require that we change the way we handle extensions. But I think it will be a good change overall. Specifically, we previously handled extensions by duplicating the extended message and then adding the extension as a regular field to the duplicated message. This required also duplicating any messages that could reach the extended message. In the new world we will need a way of declaring and looking up extensions separately from the message being extended. This change also involves some notable changes to the generated code: - files are now called foo.upbdefs.h instead of foo.upb.h. This reflects the fact that we might possibly generate several different output files for a .proto file, and this one is just for defs. - we no longer generate selectors in the .h file. - the upbdefs.c no longer vends a SymbolTable. Now it vends the individual messages (and possibly a FileDef later). I think this will compose better once we can generate files where one generated files imports another. We also make the descriptor reader vend a list of FileDefs now. This is the best conceptual match for parsing a FileDescriptorSet.		9 years ago
