Adam Jackson a33623dca7 dispatch: Be even gentler about probing for GLX ... dlsym(NULL) can only see (symbols in) libraries that are loaded RTLD_GLOBAL, but our dlopen()s are RTLD_LOCAL and probably so was the one the app did if it did one. So use RTLD_NOLOAD to probe for the library even if it's LOCAL, iff the lookup is non-fatal. Having done that, don't ever load any libraries on this path. We only perform this check while resolving rendering API functions, and the window system resolution paths already load the appropriate library if they need to. Since you have to have gone through a winsys to get a context, and our resolvers only run when a function is _called_, this would only introduce a failure mode if you tried to call a function without a context bound.
