winapi 0.2.8 is used by a number of crates in our dependency graph. The
newest version of winapi is 0.3.4, which is a significant restructuring
and also more amenable to further development, e.g. adding AArch64
support. This patch does the easy work of updating as many things as
possible to winapi 0.3.4 via a simple `cargo update`:
cargo update -p atty:0.2.2 -p fs2 -p msdos_time -p parking_lot_core -p aho-corasick
and then vendoring the results of those changes.
