avutil/fifo: Deprecate old FIFO API

Browse Source

Unfortunately AVFifoBuffer fields cannot be marked as deprecated because
it would trigger a warning wherever fifo.h is #included, due to
inlined av_fifo_peek2().

av_fifo_generic_peek(), av_fifo_generic_read(), av_fifo_generic_write(),
av_fifo_realloc2(), av_fifo_grow(), av_fifo_drain() and av_fifo_peek2().

Add a new FIFO API, which allows setting a FIFO element size.
This API operates on these elements rather than on bytes.
