Merge remote-tracking branch 'origin/5.6' into 5.7

Conflicts:
	src/corelib/io/qtemporarydir.cpp
One side encapsulated a repeated piece of #if-ery in a local define;
the other added to the #if-ery.  Made its addition to the other's.

	src/corelib/kernel/qeventdispatcher_unix_p.h
One side moved some members into a struct; this collided with a #undef
check that neither side now has.  Discarded the #undef part.

	src/gui/opengl/qopengltexturehelper_p.h
5.7 deleted a bunch of methods; not clear why merge got confused.

	src/tools/moc/moc.cpp
One added a name to the copyright header; another changed its URL.
