RC2 of 3.9

After a frantic week of file exchanges, here is RC2.  A lot has changed.

1. HP2100 updates completed, with new features and peripherals.
2. Many, many small file updates for nits found by compilers and static checkers.
3. A few genuine bugs fixed.
4. New makefile and MMS file.

A note on the makefile. It has almost doubled in size and attempts to ferret out PCAP locales properly, as well as do serious optimizations if gcc is used.  It needs to be tested in more environments.  If you run into issues, please report them to Mark Pizzolato as well as me.

The old makefile, updated for the extra files in the HP2100, is included as makefile_old.  You can use that if the new makefile causes problems in your environment.

I'm still targeting a May Day release, with a final RC around Tax Day (April 15).  That leaves times for one more interim RC, if needed.

At this point, I regard the release as feature-complete.  Bug fixes are still fine.

The actual release will have all incomplete and beta simulators in a separate zip file, including Alpha, Sigma, Sage (the microcomputers, not the 50s anti-aircraft computer), and SC1, the SiCortex MIPS simulator.
There will be new releases of all the simulation tools as well.
