does not compile with newer ffmpeg versions (FF_INPUT_BUFFER_PADDING_SIZE)

[macearl]

for newer ffmpeg versions FF_INPUT_BUFFER_PADDING_SIZE in scan.c needs to be renamed to AV_INPUT_BUFFER_PADDING_SIZE to be able to compile again

closed, as i meant to open this issue over here: https://github.com/Moonbase59/loudgain

edit: actually this issue also exists in this version, so reopened

sorry for the confusion
