Subject: [PATCH 3/3] Documentation: core-api: Add error pointer functions to kernel-api

Bring the error pointer functions (e.g. ERR_PTR(), PTR_ERR()) into
the docs build so that they can be cross-referenced elsewhere.

List them as kernel library functions in the kernel-api document.
Nowhere else seems to fit, and they need to go *somewhere*.
