Add a new type to support specifying NUMA identifiers in Rust allocators
and extend the allocators to have NUMA id as a parameter. Thus, modify
ReallocFunc to use the new extended realloc primitives from the C side of
the kernel (i.e. k[v]realloc_node_align/vrealloc_node_align) and add the
new function alloc_node to the Allocator trait while keeping the existing
one (alloc) for backward compatibility.
This will allow to specify node to use for allocation of e. g. {KV}Box,
as well as for future NUMA aware users of the API.

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.
