Access to modpaths via VPI
...
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.

Make vpi_put_value to a real accept an integer value and add diagnostic code.
...
Modified the code that deals with real variables to accept an integer
value when using vpi_put_value(). Also added some type of diagnostic
message for all switch defaults that have an assert(0) to indicate an
error condition, removed CVS comments and removed a small section of
unreachable code.

Delay compiletf until bindings are complete
...
Delat the compiletf calls until after all the label references
are resolved and link bindings are complete. Otherwise, there may
be dangling references.

Start runtime trace aids
...
The runtime is a vvp runtime engine debug aid that allows for
detailed dump into a debug log. The trace is enabled by setting
the VVP_DEBUG variable and activating specific debug messages
in the vvp source.
