insane: Improve patch warning/error handling

Currently, whilst patch errors or warnings are shown, the errors don't stop builds.
The configuration isn't very configurable from WARN_QA and ERROR_QA either.

This patch:
 * Uses the standard mechanisms to handle the patch fuzz warnings/errors
 * Makes Upstream-Status checking configurable from WARN/ERROR_QA
 * Allows that checking to be used with non-core layers
 * Makes patch-fuzz an error by default

(cherry picked from commit 3c3fd6a65e8103f74ae382d196d486b31a168b39)

The backported commit was modified to not mark "patch-fuzz" as an error
by default (which retains compatibility with kirkstone behaviour).
