Each time a codec is enabled or disabled with the umbrella
--enable-vpN flag, set the encoder and decoder configurations as well.
This was done as a post-processing step but doing that lost the order of
the arguments.

(cherry picked from commit 4c83fdd3)

Since combining VPX_DL_REALTIME with VPX_RC_FIRST_PASS is basically
nonsense, ignore the user's pass setting when this happens and
behave as if the requested encode is a single pass encode.

The logic can be incorporated into configure.sh

Removes a dependency on ios-version.sh which was not part of DIST-SRCS
and removes a warning from 'make dist' sub builds:

This commit change to use int64_t to represent the sum of pixel
differences, which can be negative.

This fixes a number of ubsan warnings.

For VBR: (1) allow newmv mode for golden ref to
select interpolation filter (as in last ref case), and
(2) don't use the more aggressive tx-skip testing logic for large blocks.

Only affects 1 pass real-time vbr mode (speed >= 5).

PSNR/SSIM metrics on ytlive set are all positive, ~0.5-2% gain.

This change is only for real-time mode if short_circuit_low_temp_var
is on. Add bias to last frame in choosing ref frame for partitioning,
when y_sad and y_sad_g are close. It speeds up real-time encoding by
0.5% on some clips with less than 0.1% overall PSNR drop on rtc test set.
