cacao: first support of cacao in oe

* for now we only support cacao-cldc
* with cacao-cldc and midapth wie have midp support in oe
* opera-mini and serval other midlets should work now
* installing the packages is not enough
* you have to write shellscripts which looks like
  http://midpath.svn.sourceforge.net/viewvc/midpath/trunk/bin/midpath-test-cacao-cldc.sh?view=markup
* arm is the only support platform for now, others will breakout at not finding
  genoffset.h, which can only generate at the target device with the 
  binary genoffset, upstream is working on diffrent solution, feel free to
  submit genoffset.h for your architecture or machine
