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.

8c72a76844
Another attempt at clean up of error handling and reporting. It's OK on limux and cygwin, but Windows VisualC is being stubborn. I would prefer not to have to call exit(1) just for Windows, since then nothing is reported and the gui disappears in a puff of smoke. Even without the exit calls nothing gets reported with the Windows gui which will hang when there are errors detected by d_process.

Use Xspice cm_message_send to report errors rathen than printing to stderr and calling exit. When a d_process model has errors found in start(), sendheader(), and dprocess_exchangedata() these are reported, but if the model is run a SIGINT is raised. There must be a better way of stopping the simulator.

Add Windows Visual Studio support for the Isotel d_process xspice digital model. The Isotel mixedsim-master/examples/embedded/motorforce C code needs to have minor changes for _MSC_VER defines, and are not included with this commit. The changes relate to using #pragma pack(push, 1)...#pragma pack(pop) around some structs, and setting stdin/stdout in binary mode. It is doubtful that the cfunc.mod will compile on mingw or cygwin since I don't know if they support pipe/fork/exec/spawn calls. The code builds and runs on Windows, Linux, and MacOS. In the future, Giles Atkinson is looking at allowing Xspice models to load shared libraries (.dll, .so) which will avoid creating and communicating with an external program.

modtabhash, which allows linear search time and makes simulation
of a 200k transistor circuit with IHP PDK possible. Already
the setup time for 15k transistor circuits has been reduced.
