- Add more to the ObjC dir readme. - Merge the ExtensionField and ExtensionDescriptor to reduce overhead. - Fix an initialization race. - Clean up the Xcode schemes. - Remove the class/enum filter. - Remove some forced inline that were bloating things without proof of performance wins. - Rename some internal types to avoid conflicts with the well know types protos. - Drop the use of ApplyFunctions to the compiler/optimizer can do what it wants. - Better document some possible future improvements. - Add missing support for parsing repeated primitive fields in packed or unpacked forms. - Improve -hash. - Add *Count for repeated and map<> fields to avoid auto create when checking for them being set.
