382609b04e tools: add Cancellable, start a futures submodule 
To make a future cancellable, use:
let (future, canceller) =
    crate::tools::futures::cancellable(future);

Proceed with using `future` as usual, `canceller` is
clonable and can cancel the future via the `.cancel()`
method.

9cdda3f7c7 tools: add helpful vector and read operations 
After importing the I/O ops trait via:
    use crate::tools::io::ops::*;

Instead of:
    let mut buffer = vec![0u8; 65536];
    file.read_exact(&mut buffer)?;
use:
    let buffer = file.read_exact_allocated(65536)?;

After importing the vector helpers via:
    use crate::tools::vec::{self, ops::*};

For a buffer which *could* be uninitialized but you prefer
zero-initialization anyway for security reasons, instead of:
    let mut buffer = vec![0u8; len];
use:
    let mut buffer = vec::undefined(len);
which zero-initializes, but, if the `valgrind` feature flag
is enabled, marks the vector as having undefined contents,
so reading from it will cause valgrind errors.
