Merge remote-tracking branch 'origin/stable' into dev

For the conflicts in msvc_nmake.cpp the ifdefs are extended since we
need to support windows phone in the target branch while it is not there
in the current stable branch (as of Qt 5.2).

Conflicts:
	configure
	qmake/generators/win32/msvc_nmake.cpp
	src/3rdparty/angle/src/libEGL/Surface.cpp
	src/angle/src/common/common.pri
	src/corelib/global/qglobal.h
