Revert "Reland "Allows FEC generation after pacer step.""

Browse Source 
This reverts commit 19df870d924662e3b6efb86078d31a8e086b38b5.

Reason for revert: Downstream project failure

Original change's description:
> Reland "Allows FEC generation after pacer step."
> 
> This is a reland of 75fd127640bdf1729af6b4a25875e6d01f1570e0
> 
> Patchset 2 contains a fix. Old code can in factor call
> RtpRtcpImpl::FetchFec(). It should only be a noop since deferred fec
> is not supported there - we shouldn't crash.

> > This CL enables FEC packets to be generated as media packets are sent,
> > rather than generated, i.e. media packets are inserted into the fec
> > generator after the pacing stage rather than at packetization time.
> >
> > This may have some small impact of performance. FEC packets are
> > typically only generated when a new packet with a marker bit is added,
> > which means FEC packets protecting a frame will now be sent after all
> > of the media packets, rather than (potentially) interleaved with them.
> > Therefore this feature is currently behind a flag so we can examine the
> > impact. Once we are comfortable with the behavior we'll make it default
> > and remove the old code.
> >
> > Note that this change does not include the "protect all header
> > extensions" part of the original CL - that will be a follow-up.
