Revert "Refactor FEC code to use COW buffers"

Browse Source 
This reverts commit eec5fff4df92b2330e5fec67ff08c7cbb4c4ab8d.

Reason for revert: Some crashes found by the fuzzer

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 replaces
> |uint8 data[IP_PACKET_SIZE]| with |rtc::CopyOnWriteBuffer data| in Packet class,
> removes |length| field there, and does necessary changes.
> 
> This is a reland of these two CLs with fixes:
