the templates are now friendlier for usage outside of libfirm

Just state the copyright and the project the files belong to. You can
then find the COPYING file for the whole project.

Get away from the strange set_default_XXX_op style and instead let the

backends can use this to allow all mux nodes which get optimized away by
the middleend anyway.
This fixes abs handling on sparc.

set_value_of_func() can be used to set a new semantic or restore the default behavior.
