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

Drop post-configure target from several Qt5 ports.

Qt's configure script already creates all the necessary Makefiles for the
directories we need to build, so there is no need to run qmake again in
post-configure.

Update Qt5 to 5.4.1.

This is probably the first time our Qt 5 ports are tracking the latest
upstream release :-)

There isn't much to report in this update, thanks to the effort spent in the
5.2->5.3 update: a lot of the work is just small plist and patch updates.
Thankfully, several patches have been upstreamed and are not needed on our
side anymore.

I would like to thank Alex Richardson <arichardson.kde@gmail.com> and Tobias
Berner <tcberner@gmail.com> for their help with the plist updates and
general testing.

Update Qt5 ports to 5.3.2.

Proudly presented by the KDE on FreeBSD team, with several guest stars.

This update took way longer than initially expected due to us previously
accumulating assumptions and changes to Qt's build system that finally bit
us back with the 5.3 release series, so we had to do a fair amount of
cleanup.

New ports:
- comms/qt5-serialport: Qt functions to access serial ports, originally
                        based on work by Fernando Apesteguia. [1]
- devel/qt5-qdoc: Qt documentation generator, the Qt5 equivalent of
                  devel/qt4-qdoc3. Originally worked on by Tobias Berner.
                  It had already been half-split from devel/qt5-buildtools,

KDE/FreeBSD team is happy to present Qt 5 in ports!

Alberto Villa (avilla@) has done all the hard work to create Qt 5 ports.
Trivial update from 5.2.0-beta1 to 5.2.1 by me.

Special thanks for Adriaan de Groot <groot@kde.org> for his assistance for
Qt-5.2.0 update.
