Code:  void P2PQuicStreamImpl::OnStreamReset(const quic::QuicRstStreamFrame& frame) {
  quic::QuicStream::OnStreamReset(frame);
  delegate_->OnRemoteReset();
}

Vulnerability Type: Bypass 
CWE ID: CWE-284
Summary: The TreeScope::adoptIfNeeded function in WebKit/Source/core/dom/TreeScope.cpp in the DOM implementation in Blink, as used in Google Chrome before 50.0.2661.102, does not prevent script execution during node-adoption operations, which allows remote attackers to bypass the Same Origin Policy via a crafted web site.
Commit Message: P2PQuicStream write functionality.

This adds the P2PQuicStream::WriteData function and adds tests. It also
adds the concept of a write buffered amount, enforcing this at the
P2PQuicStreamImpl.
