Add guest_sbi_probe_extension(), allowing guest code to probe for SBI extensions. As guest_sbi_probe_extension() needs SBI_ERR_NOT_SUPPORTED, take the opportunity to bring in all SBI error codes. We don't bring in all current extension IDs or base extension function IDs though, even though we need one of each, because we'd prefer to bring those in as necessary.

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.
