Fix the reporting of failed tests as it was broken in several ways. First, a failed test was reported as both failed and passed messing up the count. Second, tests were not aborted after a failure and could generate more "failures" messing up the count even more. Third, the failure reporting from the application to the shell script was wrong. It always reported pass. And finally, the handling of the failures in the launch script was not correct. Correct all this by propagating the failure up through the function calls to a calling function that can abort the test. A receiver or sender thread will mark the new variable in the test spec called fail, if a test has failed. This is then picked up by the main thread when everyone else has exited and this is then marked and propagated up to the calling script. Also add a summary function in the calling script so that a user does not have to go through the sub tests to see if something has failed.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
