Also tweaks to other features and experiments with
what is on and off at different speed settings.

comment out some unused parameters and adjust the format to avoid:

The aligned array in parameter list caused win32 build to report
c2719 error. This commit fixed the issue by make the parameter
type a pointer instead of an array.

Each frame we reset all adaptive thresholds to MAX
rather than base. As modes are picked their thresholds
drop down.

Renamed cpi->sf.first_step to cpi->sf.reduce_first_step_size
and changed its meaning such that it is a delta applied to
reduce the default first step size (>> x) in the motion search
rather than an absolute value.
The default first step size is already changed according to the image
dimensions (smaller for smaller images). cpi->sf.reduce_first_step_size
now applies a further correction from the default.

The part where we align it by 8 or 16 is an implementation detail that
shouldn't matter to the outside world.

Makes first 50 frames of bus @ 1500kbps encode from 3min22.7 to 3min18.2,
i.e. 2.3% faster. In addition, use the sub_pixel_avg functions to calc
the variance of the averaging predictor. This is slightly suboptimal
because the function is subpixel-position-aware, but it will (at least
for the SSE2 version) not actually use a bilinear filter for a full-pixel
position, thus leading to approximately the same performance compared to
if we implemented an actual average-aware full-pixel variance function.
That gains another 0.3 seconds (i.e. encode time goes to 3min17.4), thus
leading to a total gain of 2.7%.

This commit enables 8x8 DCT and hybrid transform unit tests. It
also tunes the forward hybrid transform rounding opertions for
more precise round-trip performance.
