This patch adds setting to override calculated bit rate outputted
into ASF stream. This is needed in the cases where ASF muxer
receives stream in TS (for example) and can't correctly determine
what output bit rate should be.

Windows Media Player actually uses ASF bitrate setting to calculate
how much to cache and if the output bit rate is wrong it tries to
cache too much or too little.

To test the behaviour before this patch try to stream WMV in TS
container to another VLC that remuxes it into ASF. Open the remuxed
stream into WMP and you'll see how it tries to cache 1%, 2%, 3%
and so on...

Small cleanup in asf muxer. Use SOUT_CFG_PREFIX in options setup.

(Cosmetic, it will allow cleaning up a bit the vout thread).

Could someone with good vout knowledge review this commit ?

This allows playing of MS Video 1 file but it is not yet correct because
of the way VLC handles RGB (it won't work on big endian, and the colors
seem broken).

Schroedinger is a fast decoder of the Dirac video codec.  This plugin
is currently the most complete dirac decoder (compared with ffmpeg or
codec/dirac.c) and should ideally be used in preference

- Input data blocks are handed over to schro which eventually free's them
  (avoids memcpy).  Freed by SchroBufferFree()
- Share picture storage between schro and vlc -- avoids memcpy of picture
  data after decoding.  Freed by SchroFrameFree()
- Autodetection of libschroedinger in configure.ac
  May be disabled with --disable-schroedinger
- Bumped decoding priority to 200, to beat libavcodec.c and dirac.c,
  this module does a better job than either of them.

- Remove potential memory leak when allocating pictures
- Always use p_block rather than priv in SchroBufferFree
- Performs pts interpolation for streams that do not have one pts per picture
- Set progressive, top_field_first and nb_fields on picture_t's properly
- Fix copyright date in header
- Reorder picture_pts_t structure for efficiency
- Print 64 bit types correctly with "%"PRId64
- No need to p_buffer->i_buffer=0 before buffer_Release()
- Work around schroedinger's lack of handling multiple parseunits per block
- Work around corrupt data produced by demux/ts.c after discontinuity
- Correctly reset decoder at Dirac END_OF_SEQUENCE
- Split decoding loop into two parts:
   - First, injecting [valid] parse units into the decoder
   - Second, itterating the decoder

When i_size is sufficiently large, we would overflow malloc(), and then
overwrite the heap with stream_Read().
