ARNR filtering is now forced to be centered on the ARF
frame and the other two options have been removed.

The other modes of constructing the ARNR frame were
not used and there does not seem to be any good
reason to maintain them.

This is purely an encoder-side change.

For speed 3 and above, such search is only allowed at speed 3.
The change helped cif and stdhd set by 1.2% and .7% in compression,
but increased the encoding time by around 5%.

Adds test code to verify that supplemental superframe information
that precedes the normal superframe information will not break
decoding.

The end_useage parameter  is confusingly named since it
now actually defines the rate control method used.

This commit enables a background detection approach for adaptive
quantizer control. It combines the cyclic refresh pattern and the
background information to determine the segment id for adaptive
quantizer selection, prior to the non-RD mode decision process.
It hence allows proper quantization information update for a more
precise rate-distortion modeling in the non-RD mode decision.

The compression performance of speed -5 for rtc set is improved
by 2.5%, at no speed change.
