David Tolnay e84e100f06 Delete extern crate lines 
Summary:
`extern crate` is usually no longer needed in 2018 edition of Rust. This diff removes `extern crate` lines from fbcode where possible, replacing #[macro_use] with individual import of macros.

Before:

```
#[macro_use]
extern crate futures_ext;
extern crate serde_json;
```

After:

```
use futures_ext::try_boxfuture;
```

radixbuf

Radix tree based on plain buffers.

There are 2 plain buffers:

  • Radix buffer: One or more radix trees mapping keys to their IDs. Read and write by the library.
  • Key buffer: The source of truth of full keys. Read by the library, write by the application.

An ID of a key could be an offset, or other meaningful numbers understood by the function reading a key.
