Fix trac ticket #2128.

We dont use au_read_packet() anymore and block_align is already set.
Thus nothing had to be merged from these.

* commit '2613de88':
  au: do not set pkt->size directly
  au: set block_align and use it in au_read_packet()

* commit '9a7b5688':
  au: set bit rate

This is required by RFC 3550 (section 6.5):

   The list of items in each chunk MUST be terminated by one or more
   null octets, the first of which is interpreted as an item type of
   zero to denote the end of the list.

This was implicitly added as padding before, unless the host name
length matched up so no padding was added.

This makes wireshark parse the packets properly if other RTCP items
are appended to the same packet.

Use the libavutil replacement.

Add some additional checks for EOF and print error messages on an incomplete
header or packet.

FATE reference updated for id-cin-video due to the demuxer no longer
returning a partial video packet at EOF.

This matches the AVInputFormat.read_packet() API.

Also, do not allow seek-by-byte, as there is no way to find the next packet
boundary.

Also, use 1 / sample_rate for audio stream time_base.

chunk_size is unsigned 32-bit, but av_get_packet() takes a signed int as the
packet size.

Avoids using unsupported parameters and signed integer overflows.
