Keep the same transform cutoff and partition selection
for speed 5 as in speeds >=6 (non-rd speed settings).
Existing setting for key frame at speed 5 allowed transform size
up to 32x32 on key frames, and did not allow for 4x4 block partition size.
This created more visual artifacts on first few frames.
avgPSNR/overallPSNR/SSIM gains of 0.2/0.7/0.8 for rtc_derf(low-res) set,
and 0/0.7/1.1 gains for rtc set.

For speed 5 real-time mode, the selection of the partition size for
superblocks on the segment (aq-mode=3) uses the non-rd recursive
pick partition search, and can sometimes select 64x64.
For low resolutions, visually better to limit this to 32x32.

For screen content don't refresh a block at a quantizer higher than
it was last coded at. PReviosuly at realtime speeds the encoder had a
tendency to recode a block from GOLDEN with a higher Q than it was last
coded at.

Decision to scale down/up is based on buffer state and average QP
over previous time window. Limit the total amount of down-scaling
to be at most one scale down for now.
Reset certain quantities after resize (buffer level, cyclic refresh,
rate correction factor).
Feature is enable via the setting rc_resize_allowed = 1.

The internal behavior of block_yrd differs in high bit depth
settings from 8-bit one. This causes the assertion condition not
true for high bit depth.

The overflow issue affects a variable that is only used in inter
mode. This commit fixes the ioc warning triggered in the intra
mode. It does not affect the compression performance.

set_frame_size() is being called twice, once before entering
encode_encode_frame_to_data_rate(), and once again in that function.
No need to call it twice for one-pass mode.

This patch modified the thread creating code. When use_svc is true,
the number of threads created is decided by the highest resolution.
This resolved WebM issue 1018.

This commit fixes a potential integer overflow issue in function
hadamard_16x16. It adds corresponding dynamic range comment.

If the frame size increases, the tile data buffer needs to be
re-allocated according to the number of tiles existing in current
frame. This patch makes the multi-tile encoding work in spatial
SVC usage case, and partially solved WebM issue 1018.
