Changed several enums from Memmap.h to be static vars and implemented Get functions to query them. This seems to have boosted speed a bit in some titles? The new variables and some previously statically initialized items are now initialized via Memory::Init() and the new AddressSpace::Init(). s_ram_size_real and the new s_exram_size_real in particular are initialized from new OnionConfig values "MAIN_MEM1_SIZE" and "MAIN_MEM2_SIZE", only if "MAIN_RAM_OVERRIDE_ENABLE" is true. GUI features have been added to Config > Advanced to adjust the new OnionConfig values. A check has been added to State::doState to ensure savestates with memory configurations different from the current settings aren't loaded. The STATE_VERSION is now 115. FIFO Files have been updated from version 4 to version 5, now including the MEM1 and MEM2 sizes from the time of DFF creation. FIFO Logs not using the new features (OnionConfig MAIN_RAM_OVERRIDE_ENABLE is false) are still backwards compatible. FIFO Logs that do use the new features have a MIN_LOADER_VERSION of 5. Thanks to the order of function calls, FIFO logs are able to automatically configure the new OnionConfig settings to match what is needed. This is a bit hacky, though, so I also threw in a failsafe for if the conditions that allow this to work ever go away. I took the liberty of adding a log message to explain why the core fails to initialize if the MIN_LOADER_VERSION is too great. Some IOS code has had the function "RAMOverrideForIOSMemoryValues" appended to it to recalculate IOS Memory Values from retail IOSes/apploaders to fit the extended memory sizes. Worry not, if MAIN_RAM_OVERRIDE_ENABLE is false, this function does absolutely nothing. A hotfix in DolphinQt/MenuBar.cpp has been implemented for RAM Override.
