It is basically a wrapper around av_get_audio_frame_duration(), with a
fallback to AVCodecContext.frame_size. However, that field is set only
when the stream codec context is actually used for encoding or decoding,
which is discouraged.

For muxing, it is generally the responsibility of the caller to set the
packet duration.
For demuxing, if the duration is not stored at the container level, it
should be set by the parser.

Therefore, removing the frame_size fallback should not break any
important case.

The cur_*auth_type variables were set before the http_connect call
prior to 6a463e7f - their sole purpose is to record the
authentication type used to do the latest request, since parsing
the http response sets the new type in the auth state.
