Proposed patch

This is in preparation for the Qt 5.6.2 -> 5.7.1 update (bug 216797): Qt 5.7 requires C++11 support.

VLC 2.2.4 has issues building in C++11 mode, so incorporate a few upstream commits to make things work, and adjust the atomics-related patches landed in ports r416225, as including <atomic> only with libc++ >= 3.8.0 leaves out FreeBSD 10.3. include/vlc_atomic.h is now closer to its git (post-2.2.4) version, in that we now have 3 possible conditions:
1. The header is included in C11 mode, in which case <stdatomic.h> is included.
2. The header is included by C code but we're not building in C11 mode, in which case some shims are defined.
3. The header is included by C++ code, so we can assume C++11 and just include <atomic>.

It will likely be possible to drop the changes once a new VLC version is released, as upstream has since started requiring C+11 and passes the appropriate flags to the compiler.
