Non-RGB output always uses full chroma interpolation.

Fixes hangs if the last packet contains an end-of-sequence NAL unit,
bug 158.

This fixes compilation failures related to START_TIMER/STOP_TIMER macros and
-Werror=declaration-after-statement.  START_TIMER declares variables and thus
may not be placed after statements outside of a new block.

also add more documentation about the header structure

avctx->frame_size is 32, so that is how many samples we process per call.

fixes seeking

It is already set by avcodec_alloc_frame().

Fixes bug 188.

The reference encoder does not generate any streams using this, but the
reference decoder can handle it, so we should as well.

This isn't used by the reference encoder, but it is supported by the decoder.

Now that there is official documentation from Apple about this, we don't have
to guess anymore.

Add it to doc/APIchanges and update and correct other entries.

This means that avformat_find_stream_info() now works properly with
multiple threads, so there's no need to force thread count to 1.
