Initial-checkin for ON2 Software AVC/H264 decoder
o when neon is present, the performance gain of On2 AVC software decoder
over PV software decoder is more than 30%.
o In addition, it fixes some known PV software decoder issues like missing
output frames
o allow both pv and on2 software avc to be available for easy comparision
o change output frames from 8 to 16
