This patch adds support for the other edges 01, 10, etc. These still
need to be verified in the context of IOPATHs, but they are ignored
in the timing checks and that's what was needed.
This patch updates the compiletf for $sdf_annotate() to better
check the arguments and to display the file and line location
when an error/warning does occur. It does the same for the
calltf messages. It also fixes a couple of subtle bugs.
First we need to look for a NULL string not a NULL value. The
result buffer should always be defined so will never be NULL.
Next if a scope has no modules we should return like the module
was not found (return 0) vs asserting.
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.
The second argument of $sdf_annotate is the scope that is to be
annotated. The argument is optional, and the default is to annotate
the current scope, where the $sdf_annotate is invoked.

Handle the special case that the SDF CELL instance is empty. In this
case, the SDF file is requesting the current scope instead of an
instance within the scope.

Implement extended vvp command line options to control the amount
of detail that the sdf annotator emits while parsing the source
file.

Pass parsed SDF delays into the vvp run time as vpiScaledRealTime
variables, and handling the mapping of 2-values to 12-delays.
