Can we change this into an enum that has kIncoming and kOutgoing to make this
mistake harder?

I suppose we could do that, though I think the origin of this bug is that the
RTCP packet is passed to a SendStream, which on first glance looks as if it is
outgoing.

There is an enum RTPDirections in common_types.h. Do you think I should reuse it
(for both RTP and RTCP), or should I create a new enum in rtc_event_log.h?

Added an enum in rtc_event_log.h
