It's an evil hack that assumes an AVIOContext is always based on top of
an URLContext.
It's also not used anywhere.

In most cases, s->buf_ptr will be equal to s->buf_end when
fill_buffer is called, but this may not always be the case, if
we're seeking forward by reading (permitted by the short seek
threshold).

If fill_buffer is writing to s->buf_ptr instead of s->buf_end (when
they aren't equal and s->buf_ptr is ahead of s->buffer), the data
between s->buf_ptr and s->buf_end is overwritten, leading to
inconsistent buffer content. This could return incorrect data if
later seeking back into the area before the current s->buf_ptr.

If there is little unread data in the ByteIOContext buffer, this may lead
to reducing the size of the ByteIOContext buffer to little more the probe
data size. This can lead to suboptimal aviobuf behaviour, e.g. making some
demuxers fail to do short seeks backwards (if the input isn't seekable).
