Module libffi::middle

Middle layer providing a somewhat safer (but still quite unsafe) API.

The main idea of the middle layer is to wrap types ffi_cif and ffi_closure as Cif and Closure, respectively, so that their resources are managed properly. However, calling a function via a CIF or closure is still unsafe because argument types aren’t checked. See the high layer for closures with type-checked arguments.
