ffi: allow init-forms for slots.

* ffi.c (ffi_memb_compile): Don't complain about
three-argument slot specifiers, only about longer ones.
(ffi_struct_init): New static function.
(ffi_type_compile): Deal with third element in the slot
syntax. If there are any non-nil initializing expressions,
then we when we call make_struct_type, we specify an initfun,
which will plant the values into the slots, using logic
similar to that of the initfun generated defstruct,
except that the init-forms are reduced to values up-front.

* txr.1: Specify optional init-form for slots in FFI
struct syntax.
