When the packet size is known in advance like here, one can avoid
an intermediate buffer for the packet data by using
ff_get_encode_buffer() and also set AV_CODEC_CAP_DR1 at the same time.

Given that the AVCodec.next pointer has now been removed, most of the
AVCodecs are not modified at all any more and can therefore be made
const (as this patch does); the only exceptions are the very few codecs
for external libraries that have a init_static_data callback.

If a bit is reserved, it matters very much what value it has, because
otherwise a decoder conforming to a future version of the standard might
interpret the output file in an unintended manner. This implies that
one must not use skip_put_bits() for it (which does not give any
guarantees wrt what ends up in the output (in case of a little-endian
bitstream writer (as here) it writes a 0 bit)); given that the reference
encoder as well as the earlier code write a zero bit at this place, the
new code does, too.
