ad6150f769 Recalibration of bits per MB tables
The baseline bits per MB prediction tables have been
re calibrated based on the assumption that bits per mb
is inversely proportional to the quantizer level.

c239a1b67c Improved Force Key Frame Behaviour
These changes improve the behaviour of the code with
forced key frames sent in by a calling application.

The sizing of the frames is still suboptimal for two pass in
particular but the behaviour is much better than it was.

99f46d62d9 Moved gf_active code to encoder only
The gf_active code is only used by the encoder, so it was moved from
common and decoder.

bf18069ceb Rate control fix for ARNR filtered frames.
Previously we had assumed that it was necessary to give a full frame's
bit allocation to the alt ref frame if it has been created through temporal
filtering. This is not the case. The active max quantizer control
insures that sufficient bits are allocated if needed and allocating a
full frame's worth of bits creates an excessive overhead for the ARF.

94c52e4da8 cosmetics: trim trailing whitespace
When the license headers were updated, they accidentally contained
trailing whitespace, so unfortunately we have to touch all the files
again.
