The bits are not wasted, they are additional low bits that are added to the
16-bit decompressed samples to increase the output sample depth.

Also rearranges some functions for easier cleanup on failure.

reduces memory usage when the stream has fewer than MAX_CHANNELS

check frame header channel count against header/container channel count.

It is already done when using it to set sample_fmt.

Otherwise the delay expressed in has_b_frames increases with every
avcodec_close/avcodec_open.

Without this patch each displayed second is incremented 1 frame early,
second 0 is only 24 frames long where as every other second is 25 frames
long.

It is broken because an AVCodecContext can be opened/closed multiple
times, and sample_rate is getting divided by 2 each time that happens.

This removes the only use of lowres for audio.

using a floating-point calculation is not necessary.

Note that this will not work in most cases with avconv and avplay due to the
AVCODEC_MAX_AUDIO_FRAME_SIZE limit, but it will decode correctly if given a
large enough output buffer.

TTA does not support float at all, and format 2 is encrypted TTA.

It's only used in avconv, so it properly belongs to OutputStream struct
there.

Prevents -c copy from working for input streams and allows to move
stream_copy variable from AVStream to OutputStream.

Deprecate AVFormatContext.preload.

The situation was not clear when support was added but it is now:
CELT and Opus are really two different codecs.
The current code supports CELT via libcelt, not Opus.
