Cary R ae14a58bff V0.8: Remove deprecated #ident and fix some other compile warnings 
This patch removes #ident since it is deprecated in recent gcc
versions. It also removes all the CVS comments and fixes a few
other compilation warnings. There are still a few compilation
warnings, but this takes care of most of them. Fixing the rest
will require a bit more thought.

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.

steve 42e4ff47c8 Move inital value handling from NetNet to Nexus 
objects. This allows better propogation of inital
 values.

 Clean up constant propagation  a bit to account
 for regs that are not really values.

 Change vvm constants to use the driver_t to drive

 multiple drivers on a signal.
