The only guy who cared about this for a long while (since I eliminated the pre-standard protocol variants) was sending a close frame. - Set it to 0 so old code remains happy. It only affects user code buffer commit, if there's overcommit no harm done so no effect directly on user ABI. - Remove all uses inside the library. The sample apps don't have it any more and that's the recommendation now. Signed-off-by: Andy Green <andy.green@linaro.org>
