e540ca7155 vp9: SVC: Use prune_evenemore only for non_reference.
Set subpel prune_evenmore only for non_reference frames,
instead of all TL > 0 frames. Gain some quality back at
cost of small speed loss (~1-2%).

Change only effects SVC encoding at speed >= 7.

James Zern
45daecb4f7 vp8_decode_frame: fix oob read on truncated key frame
the check for error correction being disabled was overriding the data
length checks. this avoids returning incorrect information (width /
height) for the decoded frame which could result in inconsistent sizes
returned in to an application causing it to read beyond the bounds of
the frame allocation.

21d2273efa vp9 level targeting: more strict constraint on min_gf_interval
min_gf_interval should be no less than min_altref_distance + 1,
as the encoder may produce bitstream with alt-ref distance being
min_gf_interval - 1.

improvement appears to hold there as well.

For SVC 1 pass non-rd mode:
Force subpel seach off for SVC for non-reference frames

Add flag to svc context to indicate if the frame is not used
as a reference.

Little/no quaity loss, ~2% speedup.

Small speed gain (~2%) on vga clips,
RTC metrics up by ~2-3% on average.
