Summary: *Motivation*: I realize there's a bit of duplication with packet parsing code, for instance, `QuicHeaderCodec.cpp` is used in only one place, but it should be possible to de-dupe some code. First step, get rid of this unnecessary wrapper class. Reviewed By: JunqiWang Differential Revision: D17192229 fbshipit-source-id: c831abb05ae56e3ece4affd368d0f180e14fa133
