Subject: bitbake: [parser] Remove the "data" from feeder, evaluate after
 parsing a file

Evaluate the statements after having parsed one file. This is
referred to as "entwirren" and we can remove the direct evaluation
and postpone a bit, in the future we can use a cached copy instead
of parsing the original.
