Subject: [PATCH 0/4] Re-export Zeroable and zeroed() from ffi module

Currently, the Zeroable trait is defined by pin-init because pin-init
happens to use the trait. However, zeroed types are useful for many
purposes other than pin-init. Also, we wish to implement Zeroable for
types generated by bindgen. For both of these reasons, re-export
Zeroable from the ffi crate, which is a already dependency of the crates
with bindgen output.
