This is like the stdlib method drain, except that it's hard-coded to use the entire vector's range. Rust Binder uses it in the range allocator to take ownership of everything in a vector in a case where reusing the vector is desirable. Implementing `DrainAll` in terms of `slice::IterMut` lets us reuse some nice optimizations in core for the case where T is a ZST.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
