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

Cleanup klunky implementation of vpi_get/put_delays for modpath
objects. Remove some useless members.

The modpath source node defines the modpath object, and carries the
nodes for the source expression. The modpath outputs are references
by pointers to the vpiModPath that is not in itself a vpi object
any more. This makes the VPI view of a module path look like the
source-destinaiton pair that is the IEEE1364 description of the
modpath.
Add vvp support for modpath path term outputs. This also introduces
the concept of path terms and moves towards the path term in general
for getting at the endpoits of a modpath.
Clean up rather poorly written modpath vpi support, fixing the
parse of the modpath syntax element to not use pointless globals.
Collect the modpath code into the delay.cc file instead of the
inapropriate vpi_signal.cc source file.

Add support for accessing the modpath nodes via PLI,
and add support for the vpi_set_delays and vpi_put_delays
functions to set the delays on those paths.
