Dmitri Tikhonov 7d09751dbb Release 2.8.7
- [BUGFIX] Initial packet size check for IETF mini conn applies to
  UDP payload, not QUIC packet.
- Support old and new school loss_bits transport parameter.
- Use Q run length of 64 as suggested in the loss bits Draft.
- Undo square wave count when packet is delayed.
- Code cleanup; minor fixes.
