The ::pb namespace is no longer exposed due to conflicts.
Allow MessageDifferencer::TreatAsSet() (and friends) to override previous
calls instead of crashing.
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.
