bitbake: Sync with upstream.

Browse Source 
* File licence headers were sanitised causing most of the diff. 
 * cooker.py was created from bin/bitbake. 
 * cvs fetcher port option was added
 * The -f force option was fixed to work correctly
 * Multiple entries in rrecrdeps are now handled correctly
   (allows adding do_deploy to image depends)
