This race will always happen sooner or later in a multi-threaded
environment and it will over time lead to OOM.
This fix works by spinning, there are other ways by which this
can be fixed, like simply detecting the issue after it happened
and freeing the over-allocated memory or simply using a mutex.

Warning note suggested by Reimar.

The named constant needs to be searched for in the same object on which
the option is set, i.e. target_obj.

The check `src > dst' in the form `&c->out[-back] > c->out' invokes
pointer overflow, which is undefined behavior in C.

Remove the check.  Also replace `&c->out[-back] < c->out_start' with
a safe form `c->out - c->out_start < back' to avoid overflow.

The mingw win32 atomics appear to be faulty, so they should not be used
if the gcc ones are available.

Signed-off-by: Martin Storsjö <martin@martin.st>

Not all gcc configurations have an implementation of all the atomic
operations, and some gcc configurations have some atomic builtins
implemented but not all.

Thus check for the most essential function, whose presence should
indicate that all others are present as well, since it can be used
to implement all the other ones.

On the current code, armcc will fail with:
"libavutil/atomic_gcc.h", line 52: Error:  #2771: first argument must be
a pointer to integer or enumeration type

This makes them pass standalone compilation tests. Previously,
they included atomic.h which included themselves again, leading to
double definitions.
