Gerben Stavenga	36662b3735	Refactor some code. I extracted some common code from all message field parsers, to a tail recursive function. Removed the varint jmp table for a simple varint parse loop, that removes the stack frames. Also careful with not losing information in repeated message tag check. When written mindful the checks and loads that happen can be reused for tag dispatch if not the expected tag.	4 years ago
