Add more error messages to processes run for toolchain detection.
Move Windows-specific code to dbgwinutils, remove inclusion of
<windows.h>. Fix MinGW gcc 4.5 warnings.

Give warnings about failures to be able to fix things/timeouts on
slow machines. Pass on arguments correctly on Windows.
Make sure processes are killed on timeouts.

 * Detection of Qt versions from a makefile failed on windows
   when calling qmake without the drive letter. Make this work.

If no 'qmlviewer' executable is found in the PATH, iterate through the
list of configured Qt versions and try to find a qmlviewer there. This
should help users configuring creator such to play with Qml.

Right now the first qmlviewer found in a Qt version is selected. A UI
to let the user select one explicitly was not possible any more (string
freeze).

This requires a dependency from QmlProjectManager to
Qt4ProjectManager.

 * Revert this once string freeze is over!

 * Add function to check whether the new symbian build system is used
   to build a Qt version. This will be used to decide which parsers
   to use when building for symbian

make it an argument of the main entry point instead of a property

the latter does too much

 - lessens open file handles
 - improves help plugin startup further

This boils down to the same problem as other calls to qmake, if we don't
pass the target mode, qmake will prepend the current platform as target.

Handle qmake with or without trailing .exe on windows. Looks like the
extension got lost recently in the generated Makefiles.

This patch marks up invalid Qt versions as Desktop.

Make sure we add a the always existing invalid Qt version in the path
available in the targetselectionpage if no valid Qt versions could be found.

This way a project can be set up and loaded without a valid Qt version set up.
Trying to build this will fail of course. This is basically how we handled
this situation before we had targets, too.

This reverts commit b1a121c5.

Accidentally pushed the linux icc parser before it was ready.

Conflicts:

	src/plugins/qt4projectmanager/qtversionmanager.cpp

That means wrong target (though argueable we don't have a correct one
yet, but working defines and includes.
