vp9: Allow usage of lookahead for real-time, 1 pass vbr. Allow usage of lookahead for VBR in real-time mode, for 1 pass vbr. Current usage is for fast checking of future scene cuts/changes, and adjusting rate control (gf interval and active_worst/target size). Added unittests (datarate) for 1 pass vbr mode, with non-zero lag. Added an experimental option to limit QP based on lookahead. Overall positive gain in metrics on ytlive set: avgPNSR/SSIM up on average ~1-3%; several clips up by 5, 7%. Change-Id: I960d57dfc89de121c4824b9a9bf88d2814e74b56
