[webkit-qt] qt5 version updated for bot / development - IMPORTANT

[Osztrogonac Csaba]

Hi All,

I updated the Qt5 on the Qt5 WK1/WK2 buildbots, WK2 EWS and on the WK2 perf bot.
The new Qt5 hash is 74f7b7f74c0e9ce99123fc836fd22f1f0b5688fe (Thu Mar 29 16:17:33 2012 +0200)

You can find the updated build script here:
https://github.com/ossy-szeged/qt5-tools

But unfortunately there are two regressions:
- [Qt] WK1/WK2 layout test results are diverging - https://bugs.webkit.org/show_bug.cgi?id=82720
After update WK1 tests started to fail, so now the test coverage on Qt5-WK1 is 0% :(

- [Qt][WK2] REGRESSION, fix a failing API test in qmltests - https://bugs.webkit.org/show_bug.cgi?id=82700
After update a Qt5-WK2 API test started to fail

My question is what do you think about these regressions? Should we go back to the
previous pinned Qt5 hash or not? Is there any volunteer to dig/fix these regressions?

br,
Ossy
