We already have sufficient coverage for 16-bit pcm.

Otherwise the values are overwritten.

also use AVERROR codes for some return values instead of -1

simplifies the code and does less memmove()

vorbis_bitrate_flushpacket() does not return any packets that should not be
output in the bitstream.

libvorbis takes float input, so we can just deinterleave/reorder the input
as-is instead of also converting.

Fixes a segfault if init() fails before initializing the dsp state

- enable the options for audio encoding
- properly check for user-set maxrate
- use correct calling order in vorbis_encode_setup_managed()

It will be need by new functions called from mp3_write_trailer().

Unused so far.

Frame sizes in ID3v2.3 are not synchsafe, they are simply 32be numbers.

In practice this bug is not noticeable unless the frame size takes more
than 7 bits (which is almost never for text frames).

This will allow writing the tag in several steps, needed for writing
attached pictures.

It has no need of full AVFormatContext.

Rename ff_id3v2_read_all to ff_id3v2_read().
