        Optimize disk ID calculation by special-casing the handling of all-zero blocks in hash
        plus doing the necessary modifications in order to exploit that special case. In case

        the disk ID by HALF.

- Warn if audio input ID in raw audio dumper is invalid

Changes from JPC to JPC-RR Release 1:
=====================================
- Remove background compiler
        One really doesn't need the nondeterminism JIT brings.
- Remove applet code and debugger
        This is not going to run as applet and debugger isn't something I would want to keep
        up to date.
- Remove ethernet and serial port emulation
        Multi-machine emulation is nightmare to make sync.
- Make TSC exact number of instructions executed, not guess based on frequency
- Synchronize all timing to CPU

        GenericBlockDevice can handle all types of block backed by DiskImage, and DiskImage
        can handle COW (Copy-On-Write).
- Don't allow save/loadstate on running PC
        Savestating on running PC is racy and produces unusable savestate.
- Variable CPU speed/memory size/BIOS image support
- Add VGA retrace start/stop traps and timed traps
        This is frame / time advance mecanism.
- Textual status dump
        Textual status dump is powerful tool when debugging desyncs.
- Implement new savestate mechanism and remove the old
        The old mechanism just didn't cut it. New mechanism is brute-force but works.
- Video dumping support
        Support dumping video to series of PNG files
- Add tools for making image files
- Image library code
        Needed images are searched via image library.
- Handle triple faults
        Reboot PC on triple fault instead of crashing the emulator core.
- Enable start/stop as apporiate
- Don't hang the UI during savestate and related operations
- Remove mouse input support
        To be reintroduced later
- Create PC from GUI, not before it
- Allow fast exits out of CPU emulator
- Fix the "11 micro-ops" bug.
- Dedicated timer priority queue class
        The standard one from java.util.<foo> just isn't deterministic enough.
- Use stderr instead of logger
        Makes nicer-looking console output.
- Support dumping emulated RAM
- Plugins and modules support
        These are for future extensions, so devices can be added without breaking timing.
- Move previous JPCApplication/PCMonitor code to plugins
- Display errors as dialogs if GUI available, on console if not
- Event recording/playback code
- Audio dumping support + PCSpeaker audio output support
