[PATCH V4 04/17] pipeline: rework the specification file-based pipeline build

[Cristian Dumitrescu <cristian.dumitrescu@intel.com>]

Rework the specification file-based pipeline build operation to first
parse the specification file into the previously introduced pipeline
specification data structure, then use this structure to configure
and build the pipeline.
