Do closures via libffi
This removes ClosurePool. It has been switching pages protection between
writable and executable, which was making it incompatible with PaX
MPROTECT.
libffi instead leaves its closures (closure trampolines) non-executable,
relying on PaX to recognize and emulate them, which allows it to work
even under such circumstances.
Remove CUSTOM_TRAMPOLINE and USE_RAW to avoid ifdef hassle.
