Reduce usage of Q_ASSERT in autotests. Using Q_ASSERT does nothing in release-mode builds, and in debug builds it causes tests to terminate prematurely. It is much better to use QVERIFY or QCOMPARE.

Fixed tst_qprocess, tst_qtcpserver when crashing is slow These tests assumed that a crashing program will always exit within five seconds. This is not true in some situations. On our test macs, enabling crash dumps can easily cause a process to take longer than five seconds to crash. Increased the timeout to 30 seconds.

Fix QProcess emitting two started signals on X11 On X11 QProcess would emit two started signals when calling QProcess::waitForStarted(). We should expect that the private implementation of waitForStarted() should emit the started signal and return true or false appropriately.

Initial import from the monolithic Qt. This is the beginning of revision history for this module. If you want to look at revision history older than this, please refer to the Qt Git wiki for how to use Git history grafting. At the time of writing, this wiki is located here: http://qt.gitorious.org/qt/pages/GitIntroductionWithQt If you have already performed the grafting and you don't see any history beyond this commit, try running "git log" with the "--follow" argument. Branched from the monolithic repo, Qt master branch, at commit 896db169ea224deb96c59ce8af800d019de63f12
