lxdream WIP - Slipping 0.9 to October

Progress on the Sega Dreamcast emulator for Linux.

Well, it’s become increasingly clear that I’m not going to have 0.9 ready in the next 2 weeks, or even in month after that. There’s two main reasons for this - I’m unfortunately finding much less time to work on lxdream of late than originally counted on, and the OS X work pretty much took a couple of months out of the schedule by itself. In any case, based on the remaining work and current rate of progress, I’m rescheduling 0.9 for October. We’ll see how that goes ^_^.
However having said that, there’s certainly enough changes to warrant a 0.8.4 interim release, especially for OS X and x86-64 users. I have a fairly short list of things remaining that need to go into that release, so that will be out in about 2 weeks. In the meantime, if anyone’s noticed any regressions relative to 0.8.3 or platform-specific bugs, please let me know as soon as possible so they can be fixed prior to release.
