* Added deep freeze functionality
* Adding support for selecting sound chip
* Adding LUA interface to the deepfreeze list
* Implemented sprite always on top in the VDP
* Found and fixed the issue that manifested itself in a reset Gargoyles and an outright fail in Ristar. The issue was the use of a union type containing overlapping cd and cartdrige data. Using struct now to keep them separated
* Fix PC reg in tracelogs

This was benign, because libunwind will ignore a frame header it doesn't understand (__eh_frame was still fine). But now there's no spew in the console. And over the next 50 years it will save a combined 0.3 seconds of cpu time
The goal here is to provide an unwind implementation that works. We (probably) don't have a working ldso, so reconfigure libunwind to work without that. To do that, it needs __eh_frame_* variables which it can addressof to find the locations of .eh_frame and .eh_frame_hdr. There is no way I could get gold to add these at all, so switch back to ld and add a custom linkscript. The custom linkscript gives us the opportunity to simplify the savestate memory mapping stuff inside ElfLoader, which should knock a bit of time off of state loads -- those VirtualProtect calls are not cheap. This also removes a potential source of nondeterminism with certain clever out of range pointers.
Any waterbox core that I didn't recompile for this commit will assert now until it is recompiled, because .wbxsyscall is in the wrong palace.
