Ilya Nikolaevskiy eec5fff4df 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:
