Parse SDF file annotations of edge sensitive delay paths.
Add vpi support for getting the specified edge sensitivity of
an edge sensitive path, and annotate paths with proper attention
to the edge that is specified for the path.
Implement extended vvp command line options to control the amount
of detail that the sdf annotator emits while parsing the source
file.
