The KDE on FreeBSD team presents Qt 4.8.6.

This is a minor bugfix release that fortunately contains quite a few patches
that we have upstreamed in the past months.

See http://blog.qt.digia.com/blog/2014/04/24/qt-4-8-6-released/ for a
summary of changes, and
http://download.qt-project.org/official_releases/qt/4.8/4.8.6/changes-4.8.6
for a detailed list of changes.

This patch contains commits by me, makc@ and Schaich Alonso.

-From: Raphael Kubo da Costa <rakuco@FreeBSD.org>
-Date: Tue, 2 Jul 2013 13:48:28 +0300
-Subject: [PATCH] Bring in WebKit revisions 139553 and 139921.
-
-They are primarily useful for getting rid of some libstdc++-specific
-includes which break the build with libc++, and also for simplifying the
-code and removing a Darwin-specific code path.
-
-r139553 by ossy@webkit.org:
-  Use sync_add_and_fetch instead of gnu_cxx::exchange_and_add
-  https://bugs.webkit.org/show_bug.cgi?id=106729
-
-  After r139514 we need atomicIncrement(int64_t volatile*) for all
-  platform. Now the GCC implementation of atomicIncrement() is based on
-  gnu_cxx::exchange_and_add, which doesn't support int64_t type, but
-  sync_add_and_fetch does.
-
-  Reviewed by Benjamin Poulain.
-
-r139921 by benjamin@webkit.org:
-  Use GCC's implementation of atomicIncrement/Decrement on Mac
-  https://bugs.webkit.org/show_bug.cgi?id=106976
-
-  Reviewed by Filip Pizlo.
-
-  wtf/Atomics.h: GCC and LLVM have builtin for atomic ADD and SUB:
-                 sync_add_and_fetch, sync_sub_and_fetch.
-
-  Using them let the compiler just generate the atomic operations inline
-  instead of generating a function call to LibC. It also simplify the
-  code a bit.
-
-Cherry-picked from qtwebkit/0baf197 and qtwebkit/801fc96. I'm cherry-picking
-both revisions together to match what was done in 0de22e80.
