Highlights:

• Added Connection::stream_discard() to discard received stream data without copying it into an application buffer.
• Updated BBR2 default parameters to behave closer to draft-ietf-ccwg-bbr-04, disabling older experiments that could hurt bandwidth estimates, high-loss behavior, and buffering.
• Other bug fixes and performance improvements.
