steve c2070777b2 The $time system task returns the integer time
scaled to the local units. Change the internal
 implementation of vpiSystemTime the $time functions
 to properly account for this. Also add $simtime
 to get the simulation time.

steve e35ed6e91c Change the NetAssign_ class to refer to the signal
instead of link into the netlist. This is faster
 and uses less space. Make the NetAssignNB carry
 the delays instead of the NetAssign_ lval objects.

 Change the vvp code generator to support multiple
 l-values, i.e. concatenations of part selects.
