Originally, only bi-pred type of frames can use BWDREF. When
extra alt-refs are inserted in a gf group, the closest alt-ref
serves as ALTREF for the frames within the corresponding
subgroup. Therefore, the original alt-ref can be used as BWDREF
for the LF_UPDATE type of frames.
This patch further swaps the virtual indices of BWDREF and ALTREF
for those frames whose BWDREF is farther than ALTREF. As a result,
the BWDREF is always the closet backward reference frame, and the
ALTREF is the farther one.
It improves the average RD performance by
0.132% in lowres, and
0.030% in midres.
The overall gains for the ext-refs compared to the baseline are
5.486% in lowres, and
4.666% in midres.

This function was previously unused and removed in
I6bc740e778658d6f81ca54888fc6fa822d3b5ee0. I am adding it back in
with previously suggested fixes.

Mostly refactoring, but a very tiny functional change:
Do all rounding in calc_centroids() itself, instead of rounding in two
places inside palette.c
This gives a slight performance improvement for screen content:
0.078% on average.

Insert multiple arfs in a gf group to emulate multi-layer backward
reference frames structure. At maximum, two extra ARF's are inserted
in a gf group.

Originally we can have a BRF right before an overlay frame (in
display order), which might be unnecessary since we already has a
quality backward reference frame (ARF).
This patch avoids such a coding structure and improves the RD
performance by 0.086% in Avg in the lowres dataset, and 0.153 in
Avg in the midres dataset.
In the lowres dataset, significant gains are obtained for the
following sequences:
mobisode2_240p: 0.563%
keiba_240p: 0.440%
bus_cif: 0.336%
soccer_cif: 0.333%
And the performance drops only in the following four video sequences:
motherdaughter_cif: 0.028%
bqsquare_240p: 0.017%
basketballpass_240p: 0.015%
bowing_cif: 0.006%
