Improve encoding speed by 2% (using prores input)

avcodec/proresenc_aw : use AVframe primaries, transfert, colorspace for frame header instead of default (unknown, unknown, Rec601)

avoid color shift, on some decoding software

Doesn't seems to make speed loss

This tries to follow the webrtc code. For example using cliping and 64 bit as in WebRtcSpl_DotProductWithScale()
and not doing so in other places.
I could not find anything in rfc3951 and the reference code inside which would
explain what to do in these corner cases.
