Update PinNames markers

Add standard pin-names validation script & tests

Travis: Remove make.py test for events and littlefs ...

The removed tests were building applications from the content of their
respective README files. The events test was building with the full profile twice.
The first time with the repository as is; and the second time after deleting
some directories (to simulate the baremetal profile).
The littlefs test was building once with the full profile.

Testing make.py is no longer required as it is no longer supported.
There is already test coverage for APIs in the removed tests.

travis: ignore spdx reports ...

Do not force red status for PRs due to SPDX missing (license must be there). We will
add better SPDX checks later (more work required to enable these for 3rd party code).

Scancode: Fix false positive reported by scancode output analyser script ...

ScanCode can possibly return many licenses found for a single file scanned.
This commit ensures that the file is not reported as lacking a permissive license
if at least one license found in it is permissive.
Previously the script was reporting an issue if it found at least one license
in a file that was not permissive.

Additionally catch more errors and provide specific details about failures.
Provide unitest.

travis: count always with true, status return later

travis: fix license ok, return true

Travis: remove status functionality ...

Unfortunately, we need to remove status functionality as it exposes an information
it should rather not. There is no other way we can do it in the pull request coming
from forks (most of our PRs are from forks). It is better if we use pass/failure what
Travis provides. The information are in the logs. It should always print the status info at
the very end. A test should have "echo Failed with a reason...."

Merge pull request #13586 from 0xc0170/fix_travis_new_files ...

travis: license check for new files

travis: license check for new files ...

Fail if new file does not contain SPDX identifier. We only checked for changed files,
and warn if any found. This is not sufficient because new files should follow our license guide.

This fixes the problem.
