To repeat the start of the commit message in patch 5....

When reviewing tracetool patches it is often very unclear what the
expected output will be for the generated backends. Compounding
this is that a default build will only enable the 'log' trace
backend, so developers won't see generated code for other backends
without making a special effort. Some backends are also platform
specific, so can't be enabled in QEMU builds, even though tracetool
could generate the code.

To address this, introduce a test suite for tracetool which is
conceptually similar to the qapi-schema test. It is a simple
python program that runs tracetool and compares the actual output
to historical reference output kept in git.

This was inspired by noticing the now pointless "__nocheck__"
method wrapping in the inline probe functions.

Changed in v2:

 - Add tracetool info to docs/devel/testing.rst

Daniel P. Berrangé (6):
  checkpatch: cull trailing '*/' in SPDX check
  tracetool: eliminate trailing whitespace in C format
  tracetool: avoid space after "*" in arg types
  tracetool: include SPDX-License-Identifier in generated files
  tracetool: add test suite for tracetool with reference output
  tracetool: drop the probe "__nocheck__" wrapping
