Update Qt5 to 5.7.1, and unify the Qt4 and Qt5 ports some more

* Update Qt5 to 5.7.1
* Move Qt4 binaries to lib/qt4/bin
* Move Qt5 libraries to lib/qt5/lib
  By moving the libraries we should finally be able to get rid of the inplace
  upgrade bug (see ports bugs 194088, 195105 and 198720):  when Qt5's libraries
  were lying in /usr/local/lib, which would often get added by pkgconfig to the
  linker paths via dependencies, the already installed libraries were linked
  against, instead of the ones that were being built. This forced us to make
  sure, that -L${WRKSRC}/lib was always coming before -L/usr/local/lib in the
  linker flags. With this change this should no longer be the case.
* Rename some ports to match the rest (foo-qtX -> qtX-foo)
* Depend on new port misc/qtchooser [see UPDATING & CHANGES]

There are several new Qt5 ports which all have been created by Marie Loise Nolden
<nolden@kde.org>. Thanks again.

+  * Qt 4's binaries have been moved to lib/qt4/bin to match what is already done
+    to Qt 5's binaries. Since these binaries are no longer in ${LOCALBASE}/bin,
+    they also do not have the -qt4 suffix in their names any more.
+
+  * Consequently, there are no Qt 4 or Qt 5 binaries in the default $PATH, and
+    misc/qtchooser is now used to select the actual Qt binaries. In other
+    words, calling "qmake" or "moc" now goes through qtchooser, which prefers
+    Qt 5 binaries by default.
+
+    The ports framework handles this automatically. The UPDATING entry covers
+    this in more detail.
+
+  * Qt 5.7.1 requires a C++11-capable compiler to be used. qmake and CMake pass
+    the appropriate flags to the compiler (such as -std=c++11) automatically,
+    but if your port fetches Qt's build flags via pkg-config (which can be the
+    case for autotools-based ports), you might need to take care of this
+    manually by setting USE_CXXSTD in your Makefile:
+
+      USE_CXXSTD=	c++11
