Add EncodeFrameInput, pass1 thru av1_encode()

Add a new EncodeFrameInput structure encompassing the input to the
low-level encoder: a source frame buffer and the last frame buffer
where applicable.  The frame duration (in timestamp format) is also
included so the first pass can use it for stats.  The big change here is
that cpi->source etc. aren't set until we get to av1_encode() so
high-level strategy code can't use them.  Therefore, I change some TPL
stats code to use the EncodeFrameInput instead of cpi->source

Redirect control flow for the first pass through the av1_encode()
interface.  Now all frame-encoding goes via av1_encode_strategy() and
av1_encode() making first pass slightly less of a special case.

This forms part of wider restructuring and refactoring in order to
achieve a clean API separation at the entry to the low-level encoder.
