Adds verbose quality check

Vera++ and ccpcheck are not outputing to the stderr instead stdout
allowing the buildbot to extract some numbers about it.
Supports WarningCountingShellCommand in cppcheck and vera

WarningCountingShellCommand allow us to have some measurements on
the buildbot waterfall.
QA: Avoids the utilization of 3rd filedescriptor

No need to use a 3rd description on the quality check scripts.
Stderr is now redirected to stdout and filtered as needed.
