[PATCH v2 0/6] Test and linter fixups

[David Gibson <david@gibson.dropbear.id.au>]

Before starting to convert testcases to use tunbridge, I wanted to add
linting for the Python test scripts.  While doing that I discovered a
new crop of cppcheck and clang-tidy false positives, and a Makefile
bug.

Here's a batch of fixes.

I didn't manage to get through the whole testsuite with this.  I keep
getting hangs on rampstream_out, which I *think* are unrelated.

v2:
 * Actually understood why exetool was being deleted, and fixed it
   properly.

David Gibson (6):
  test: Add linting of Python test scripts
  clang-tidy: Suppress redundant expression warning
  cppcheck: Suppress the suppression of a suppression
  cppcheck: Suppress a buggy cppcheck warning
  cppcheck: Suppress variable scope warnings in dhcpv6()
  test: Don't delete exetool on make clean
