Speed up autotests

testtime.pl can be used to extract times when run from the folder as obtained from a test-log zip archive fex available from http://testresults.qt-project.org/ci/Qt5_stable_Integration/latest-success/ .

As of 5.7 , the plain text logger outputs the total test time.

Findings

• gui/painting/qcolor is ideal for profiling testlib since it performs a ton of comparisons.
• tst_QXmlSimpleReader taking 170s on Windows stands out, other than that, no spectacular issues.
• Geopositioninfosource also takes quite a while
• The sequence QEXPECT_FAIL / QTRY_COMPARE is really a bad idea since the check always times out

The logs from Android, iOS, WinCE are missing, unfortunately.

Hardcoded qWaits():

findwaits.sh greps the test sources for qWait() and produces qwait_stable_140523.log . There is clearly room for improvement (introduce QTRY_... ) but one has to be careful, some delays are there to wait until animations are finished, etc.
