• Reduce the size of generated proto headers for protos with string or bytes fields.
• Move arena() operation on uncommon path to out-of-line routine
• For iterator-pair function parameter types, take both iterators by value.
• Code-space savings and perhaps some modest performance improvements in RepeatedPtrField.
• Eliminate nullptr check from every tag parse.
• Remove unused _$name$cached_byte_size fields.
• Serialize extension ranges together when not broken by a proto field in the middle.
• Do out-of-line allocation and deallocation of string object in ArenaString.
• Streamline ParseContext::ParseMessage to avoid code bloat and improve performance.
• New member functions RepeatedField::Assign, RepeatedPtrField::{Add, Assign}.

• Avoid expensive inlined code space for encoding message length for messages

  = 128 bytes and instead do a procedure call to a shared out-of-line routine.

• util::DefaultFieldComparator will be final in a future version of protobuf. Subclasses should inherit from SimpleFieldComparator instead.

C#
