USF: Update LazyUSF2 library from ages ago, fixing several sets which were just broken. Fixed things include reading the rip region from the save state's ROM header field, and vblank interrupt timing.

This is a half assed attempt to replace Project64 with Mupen64plus, for a hoped better compatibility, and support for nicer recompiler cores for x86 and x86_64.
DONE:
* Get it working at all
* Verify old x86_64 recompiler works
* Converted x86 recompiler
TODO:
* Get new recompiler converted and working
Usage notes:
If your platform is x86 or x86_64, you may define ARCH_MIN_SSE2 for the rsp.c inside the rsp_lle subdirectory. You may also define DYNAREC and include the contents of either the r4300/x86 or r4300/x86_64 directories, and exclude the r4300/empty_dynarec.c file.
If you are not either of the above architectures, you include r4300/empty_dynarec.c and do not define DYNAREC, in which case the fastest you get is a cached interpreter, which "compiles" blocks of opcode function pointers and their pre-decoded parameters.
In either case, you do not include the contents of the new_dynarec folder, since that code is not ready for use with this library yet.
