ffi: varray feature
If an array dimension is void, it is a varray. The C
representation is pointer. The size is inferred
from the length of the object. Doesn't support get
method.
* ffi.c (struct txr_ffi_type): New bitfield flag, is_varray.
(ffi_varray_alloc): New function.
(ffi_array_in, ffi_array_put, ffi_array_out): Check is_varray
flag and use dynamic array size from object.
(ffi_type_compile): If the array dimension is the symbol
void, create a varray: a mongrel created using
make_ffi_type_pointer, but using the array functions,
plus alloc and free handlers, and the is_varray flag
being set.
