Add documentation for reliable stacktrace. This is intended to describe the semantics and to be an aid for implementing architecture support for HAVE_RELIABLE_STACKTRACE. Unwinding is a subtle area, and architectures vary greatly in both implementation and the set of concerns that affect them, so I've tried to avoid making this too specific to any given architecture. I've used examples from both x86_64 and arm64 to explain corner cases in more detail, but I've tried to keep the descriptions sufficient for those who are unfamiliar with the particular architecture. This document aims to give rationale for all the recommendations and requirements, since that makes it easier to spot nearby issues, or when a check happens to catch a few things at once.

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 Restructured Text 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.
