Update the Qt5 ports to 5.6.1.

This took longer than expected, but there are quite a few changes to the
existing ports and a few new ones.

General upstream changes:
- Starting with Qt 5.6.2, Qt will fail at configuration time if LibreSSL is
  being used. According to the discussion here:
  https://codereview.qt-project.org/#/c/154800/
  The Qt project is not opposed to LibreSSL, but does not want to mix
  support for it into the OpenSSL backend code, especially as they move
  towards supporting OpenSSL 1.1.
  People interested in LibreSSL support are welcome to submit a separate
  backend upstream, but are expected to maintain it. We (kde@) are not
  opposed to carrying some patches authored by others in the future, as long
  as they are not huge and destabilizing.
- When Qt detects the compiler supports C++11, it will pass -std=gnu++11 by
  default (this is an upstream change). You can add "CONFIG -= c++11" to
  your .pro. Qt 5.7 will require C++11.
- www/webkit-qt5: The QtWebKit module is deprecated upstream, and is shipped
  separately as a community release tarball. kde@ does not have an ETA for a
  qt5-webengine port, as it requires a huge effort (and number of patches)
  similar to maintaining www/chromium itself.
- x11-toolkits/qt5-declarative has been deprecated upstream. The last
  release is 5.5.1.

Relevant changes:
- devel/qmake5: The freebsd-clang mkspec has become the default mkspec on
  FreeBSD, replacing the outdated freebsd-g++ one that was moved to
  unsupported/ (it still works though).
- devel/qt5-qdoc: qdoc was moved to qttools upstream, but its data files are
  still in qtbase. The data files are now in the qt5-qdoc-data port.
- misc/qt5-doc: Clean up and stop requiring a compiler and fumbling with
  mkspecs. Instead of running the `configure' script, which requires a
  compiler and adjustments to the mkspecs files and also ends up building a
  new qmake binary, we now leverage USES=qmake to generate all the Makefiles
  from the top-level qt.pro. Getting this to work requires some tricks,
  though, and qt.conf.in has a longer explanation of what's being done.
  Switch to USES=gmake to be able to drop MAKE_JOBS_UNSAFE=yes.

New ports:
- comms/qt5-serialbus
- devel/qt5-qdoc-data
- x11-toolkits/qt5-quickcontrols2

Big thanks to Adriaan de Groot (groot@kde.org), tcberner@ and Loise Nolden
(nolden@kde.org) for the huge amount of work they put into this
patch. Loise in particular also sent quite a few changes upstream that were
essential for this update to work.

-Patch reworked for Qt 5.5.

-commit d5120908c74133d9fd249b920cff0dc76313f43f
-Author: Raphael Kubo da Costa <rakuco@FreeBSD.org>
-Date:   Mon Dec 28 00:46:31 2015 +0100
-
-    Stop using enum references that require C++11.
-
-    Use Qt::Foo instead of Qt::Enum::Foo, which is a C++11 extension. When
-    building with clang without -std=c++11, this results in warnings. With
-    older GCC versions, the code simply does not build.
-
-    This is similar to commit deffdaf9 ("GraphicsHelper: fix switch").
