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 is already set in avcodec_alloc_frame()

None of these symbols should be accessed directly, so declare them as
