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,
                  we just needed to finish the work.

Dead ports:
- devel/qt5-qmldevtools: Merged into lang/qt5-qml.

Minor changes:
- devel/qt5: Add x11/qt5-x11extras and the new ports to the dependency list.
- graphics/qt5-imageformats: The port now supports the JPEG2000, WEBP,
                             Direct Draw Surface and ICNS formats.
- multimedia/qt5-multimedia: The ALSA and PULSEAUDIO options are now
                             mutually exclusive due to changes introduced in
                             Qt 5.3.0 (the ALSA code is now a proper plugin
                             that is only built if PulseAudio is not used).
- x11/qt5-x11extras: Add USE_LDCONFIG since the port installs a shared
                     library.

The big changes:
- bsd.qt.mk: Set QMAKESPEC instead of QMAKEPATH. [3]
  QMAKEPATH does much more than we want now that we call qmake from the top
  of ${WRKSRC}. qmake uses QMAKEPATH when evaluating the QMAKE_MKSPECS
  property, which is in turn used by qt_config.pri to load the .pri files in
  mkspecs/modules.

  In practice, this means that if people have an older Qt installation those
  files will be used and QT_CONFIG will have values such as "gui" even if
  one is building a port like textproc/qt5-xml, which passes -no-gui to the
  configure script. Consequently, unintended code paths may be enabled or
  the configuration step can just fail if the .pro files expect values that
  are not present in the system-wide, older .pri files.

  We avoid all those problems if we use QMAKESPEC, as qmake does not take
  its value into account when evaluating the QMAKE_MKSPECS property and will
  only parse the files in the mkspec's directory (mkspecs/freebsd-clang, for
  example, instead of all the files in mkspecs).

- Stop explicitly passing ${LOCALBASE} to the compiler. [3]
  qmake's behavior has changed in Qt 5, and the paths set in QMAKE_INCDIR
  and QMAKE_LIBDIR in the mkspecs are passed before any others, such as the
  ones in the build directory themselves.

  In practice, this means that we end up with linker calls like this:

  c++ -o libfoo.so foo.o bar.o -L/usr/local/lib -L/wrkdir/build/lib
      -lQt5Gui -lQt5Core

  So if one already has Qt installed in the system, the older, already
  present version of the libraries in /usr/local/lib will be used instead of
  the newly-built ones in /wrkdir/build/lib.

  QTBUG-40825 discusses this behavior upstream, but there has been no
  agreement on a solution yet.

  For now, the solution adopted is to make the compiler and the linker aware
  of those paths but only try them last after all others, and this is
  achieved by setting the CPATH and LIBRARY_PATH environment variables when
  qmake is being used.

  In addition to setting them in CONFIGURE_ENV and MAKE_ENV, we also need to
  stop changing QMAKE_INCDIR and QMAKE_LIBDIR as well as filter those paths
  from the pkg-config calls qtbase's configure script makes.

- Call qmake from the root of the ${WRKSRC}.

  In Qt 5.3, Qt's build infrastructure has undergone some changes that make
  our previous approach of calling qmake from the directories we want to
  build stop working. Things would break even more in Qt 5.4, in which
  qtbase's configure script does not accept the -process, -fully-process and
  -dont-process arguments anymore (it always behaves as if -process had been
  used).

  Bite the bullet and start calling qmake from ${WRKSRC}. The largest part of
  this change involves changing lines in Makefiles from
    WRKSRC_SUBDIR=	foo/bar
  to
    BUILD_WRKSRC=		${WRKSRC}/foo/bar
    INSTALL_WRKSRC=		${WRKSRC}/foo/bar
  as well as adding patches to .pro files to avoid entering other
  subdirectories and removing post-configure targets that are not necessary
  anymore.

  Since qmake needs to be called from the top of ${WRKSRC} anyway, we can
  also simplify the configuration process for the qtbase ports a little.
  Looking at r10019 it is not clear why we started calling qmake in the
  pre-configure target in addition to the post-configure one (while also
  skipping it in do-configure), but we can now drop this call since letting
  configure behave as if -process had been passed means it will call qmake
  on its own and overwrite the files generated by the pre-configure call. We
  still need to call qmake in post-configure though, as the configure script
  does not pass -recursive when calling qmake and we need to be able to call
  make from any subdirectory when building.

-    Don't crash on broken GIF images
-    
-    Broken GIF images could set invalid width and height
-    values inside the image, leading to Qt creating a null
-    QImage for it. In that case we need to abort decoding
-    the image and return an error.
