Error handling improvements in cfunc.mod. Ensure that d_process.h wiil always respond to version and interface checks sent from sendheader. This is needed so that the pipe reads in sendheader do not cause Windows to hang when the interface version and in/out counts do not match. This hang was the cause of errors not being reported and the Windows gui hanging. Startup and header checks are now detected in cm_d_process, and the simulator will run but with runtime errors since a d_process model cannot be completely instantiated after initial errors. It would be good to find a means of gracefully halting the simulation run.

Another attempt at clean up of error handling and reporting. It's OK on limux and cygwin, but Windows VisualC is being stubborn.
