Revert "Update packetsLost and jitter stats any time a packet is received."

This reverts commit 84916937b70472715efe5682bc273e91c3a72695.

Reason for revert: breaking downstream projects.

Original change's description:
> Update packetsLost and jitter stats any time a packet is received.
>
> Before this CL, the packetsLost and jitter stats (as returned by
> GetStats, at the API level) were only being updated when an RTCP SR or
> RR is generated. According to the stats spec, "local" stats like this
> should be updated any time a packet is received.
>
> This CL also fixes some minor issues with the calculation of packetsLost
> (and fractionLost):
> * Packets weren't being count as lost if lost over a sequence number
>   rollover.
> * Temporary periods of "negative" loss (caused by duplicate or out of
>   order packets) weren't being accumulated into the cumulative loss
>   counter. Example:
>   Period 1: Received packets 1, 2, 4
>     Loss over that period: 1 (expected 4 packets, got 3)
>     Reported cumulative loss: 1
>   Period 2: Received packets 3, 5
>     Loss over that period: -1 (expected 1 packet, got 2)
>     Reported cumulative loss: 1 (should be 0!)
>
> Landing with NOTRY because Android compile bots are broken for an
> unrelated reason.
> NOTRY=True

# Not skipping CQ checks because original CL landed > 1 day ago.

Landing with NOTRY because ios64_sim_ios10_dbg bot is broken.
Passing all other bots.
