[PATCH v5 0/9] scripts/checkpatch: fix SPDX-License-Identifier detection

["Daniel P. Berrangé" <berrange@redhat.com>]

This is hugely expanded an update of

  https://lists.nongnu.org/archive/html/qemu-devel/2025-05/msg02040.html

In that series, Peter suggested creating standalone methods to act
as hooks to call when detecting the start/end of a file in a diff.

This implements that idea and adapts a number of existing checks
to use the new hooks.

Changed in v5:

 - Actually make boilerplate text regex work, the '/x'
   operator culls *all* whitespace from the regex, which
   was not desirable as we need space between words.
 - Fix inverted check of boilerplate result

Changed in v4:

 - Pull our boilerplate match regex to separate variable
 - Mention that SPDX is sufficient when reporting redundant
   boilerplate
 - Tweak commit message to explain indent changes better

Changed in v3:

 - Add check for redundent license boilerplate text
 - Fix check for Makefile names
