[Qt] run-qtwebkit-tests should report crashes

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Csaba Osztrogonác]

Unfortunately run-qtwebkit-tests has a serious bug. Now it runs each API test binary 
and summarizes its sub-summarys. But if a binary crashes then the sub-summary is missing 
and the result will be absolutely false positive.

run-qtwebkit-tests must report error if an API test crashes.

draft of solution

The patch is not complete yet. It's a draft, any kind of help or ideas are appreciated. :)
Added checking of crashing tests. TOTALS now includes the total number of crashing tests too. Missing sub-summary is considered as a crash. Test object with "None" output is now handled. I commented off convert_to_html function, because these modifications are to be made here too. 
I induced the crash with exit(1) in an API test (tst_qquickwebview.cpp) so I could test this.

Is this accidentally in the patch?

We still don't need this code. :)
