So long as x265_ssim() is declared in x265.h, its implementation must
be defined extern "C".

if the declaration is moved to common.h, then we can remove the C
decoration, but we should do that together with all of the pending API
changes so we don't bump the build number too frequently.  The
function is very poorly named, when it is removed from the public API
it should be given a descriptive name.
