        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
        of used space being small in comparison to total space, this cuts the time to compute
        the disk ID by HALF.
- Fix bug in assigning audio output IDs in presence of same module loaded multiple times
- 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
