remove lws_ensure_user_space from public api change return
The function has a logical problem when the size of the requested
allocation is 0, it will return NULL which is overloaded as
failure.
Actually the whole function is evil as an api, this patch moves
it out of the public API space and fixes it to return 0 for
success or 1 for fail. Private code does not need to to return
wsi->user_space and public code should only get that from the
callback as discussed on trac recently.
Thanks to Edwin for debugging the problem.
