This is a new patch that contains an update of bayer2rgb (proposed as
replacement of the former bayer2rgb) and adds the new jp462bayer plugin.

For bayer2rgb :
- Adds a "method" property, referring to the debayering algorithm choice.
  By default, it uses David's ORCed bilinear algorithm. Other methods are from
an inclusion of libdc1394's debayering library. For patent license issues (at
least in the U.S.), the "EdgeSense" method has been removed but can still be
obtained from the upstream project
(http://code.google.com/p/gst-plugins-elphel/); simpler methods than bilinear
have also been removed
- Adds the "bpp" property:
  This property allows to choose the raw bayer input format (8 bits or 16 bits)

For JP462bayer :
This algorithm allows to decode elphel camera raw streams (JP46 mode).
- "threads" property (0: auto, 1-4) : allows to decode elphel camera in
multithreading (nb: incompatible with fast rescaling feature, see next item)
- By using specified output caps (containing a subset of the original
resolution, devided by 4 or 16), the original JP46 stream will be downscaled
without decoding ("fast resizing"), which is useful for low-quality live
previews. This is currently single-threaded, therefore conflicting with the
"threads" property; if combined with e.g. threads=2, a GST_ERROR is emitted
