demux: pad even 0-size demux packet data (fixes sd_ass crash)
sd_ass relies on there being a zero byte after packet data. However
the packet allocation routines special-cased data length 0 and left
the data pointer as NULL in that case. This could cause a crash in
sd_ass if there was an empty subtitle packet. Change the allocation
routines to stop special-casing empty data and always allocate
padding. Empty packets are not so common that special casing them
would be a worthwhile optimization.
Also fix resize_demux_packet() to use MP_INPUT_BUFFER_PADDING SIZE as
the padding size, instead of a hardcoded value of 8.
