edition: Remove extern crate lines
In Rust 2018 edition, `extern crate` is no longer required for importing
from other crates. Instead of writing:
extern crate dep;
use dep::Thing;
we write:
use dep::Thing;
In this approach, macros are imported individually from the declaring
crate rather than through #[macro_use]. Before:
#[macro_use]
extern crate sys_util;
After:
use sys_util::{debug, error};
The only place that `extern crate` continues to be required is in
importing the compiler's proc_macro API into a procedural macro crate.
This will hopefully be fixed in a future Rust release.
extern crate proc_macro;
