bitbake/ast: Add optional argument for BBCLASSEXTEND 

Add an optional argument to BBCLASSEXTEND entries which gets passed to
the extention class as BBEXTENDVARIANT. Also add BBEXTENDCURR whic
is set to the current extension class name.

This mode functions slightly differently to the previous BBCLASSEXTEND
code in that PN is not changed.

(Bitbake rev: 8d3c899e0a15840c54de26d2f1fc552430517778)
