2240e92f05 atomic: Add include guards to the implementation headers
This makes them pass standalone compilation tests. Previously,
they included atomic.h which included themselves again, leading to
double definitions.

65f1d45dcc lavu: add support for atomic operations.
These could be used for reference counting, or for keeping track of
decoding progress in references in multithreaded decoders.

Support is provided by gcc/msvc/suncc intrinsics, with a fallback using
pthread mutexes.
