  1. Bump MSRV to 1.31 

    This permits `Cargo.toml` to include optional dependencies. On
toolchains earlier than 1.31, the optional dependency syntax is not
supported. With the MSRV at 1.31, any optional dependency may be
supported even if *its* MSRV is higher than *our* MSRV since only users
using a more recent toolchain will enable that dependency.

In particular, this paves the way for adding an optional `zerocopy`
dependency (prototyped in rust-lang#3407 and rust-lang#3914; see also google/zerocopy#557),
which permits many uses of libc to no longer require `unsafe` code.
