Use vpx_memset for updating the partition contexts. Thanks to Noah
for pointing out the need of refactoring in this part.

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%.
