Subject: [PATCH] qglobal.h: Do not include <algorithm>

algorithm is a rather heavy header, so we do not want to include it
everywhere. It most likely was put into qglobal, because before C++11,
swap could be found there. However, since C++11 it is located in
<utility>, which we already include. Thus drop the superfluous include.

[ChangeLog][QtCore][Potential source breaking change] The <algorithm>
header is no longer transitively included with qglobal.h. If you used
functionality from that header and relied on the transitive include, you
will now need to explicitly add the header.
