Revert "Refactor FEC code to use COW buffers"

Browse Source 
This reverts commit 7325bc3917e6dd4c92e7a18fd879ba91f0b2851f.

Reason for revert: FecTest.UlpfecTest is consistently failing.

Original change's description:
> Refactor FEC code to use COW buffers
> 
> This refactoring helps to reduce unnecessary memcpy calls on the receive
> side.
> 
> This CL is the first stage of refactoring: it only replaces
> |uint8 data[IP_PACKET_SIZE]| with |rtc::CopyOnWriteBuffer data| and does
> necessary changes.
> 
> A follow-up CL will remove length field of the Packet class.
> 
>
