  6. Lightrec: enable codebuffer option, fix Windows, move/cleanup headers 

    Codebuffer is much faster due to lightrec's 32-bit LUT optimization

Moved lightning.h to lightning-actual.h and made lightning.h include lightning-actual.h and define HAVE_MMAP for lightning, instead of defining in the Makefile which applied it to other parts of beetle, causing issues on Windows in libretro-common/vfs

  10. Fix eventcycles, add SPU Samples, allows much better performance 

    EventCycles should work up to 2048 now, now that it is used by MDEC and Timer

SPU samples option was added, audio glitches will occur in some games unless samples is 1

  11. support MainRAM at 0x0, use INVALID_PTR instead of NULL 

    This allows less code to be emitted by lightrec, but will only
be used if root user enables it with sysctl -w vm.mmap_min_addr=0

  12. Remove "Cycle Timing Check" (execute_one) dynarec option, use new lig… 

    …htrec api

This was only useful for debugging, users don't benefit from it, the config
will fallback to using the beetle interpreter if it was selected

The lightrec execute_one function this option called was removed, for
equivalent debugging pass current timestamp instead of next_event_ts to
lightrec_execute

Use lightrec cop2_notify for PGXP, update interpreter to new api
