    jsapi: Use same #defines as SpiderMonkey
    
    This pulls in js-config.h into jsapi-wrapper.h, because some of
    SpiderMonkey's #defines that are set at build time affect the public API.
    
    In addition, in mozjs24 and 31 at least, it looks like sometimes
    SpiderMonkey headers erroneously check for the presence of DEBUG instead
    of JS_DEBUG, so we should define DEBUG when JS_DEBUG is defined.
