add experimental ram-only emulua savestate code. now call savestate_persist(ss) if you want to cause it to go to disk. otherwise it will stay in memory. this might speed things up. also add experimental new ppu which can be enabled by newppu 1 in configfile. there is no reason to use it yet but i needed to do a checkin
fix some memory leaks by changing the path generation APIs to return std::string.. but it still gets strdupped by a lot of clients.
switch over more movie and savestate code to use iostreams instead of stdio
remove the temporary savestate stuff for more tasing speed hopefully
