  Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
  by denying s# to parse objects that have a releasebuffer procedure,

checks to make sure the object has the required function
pointer and issues the call. The obj must have the buffer
interface or this function will cause a segfault (i.e. it
is assumed to be called only after a corresponding
getbuffer which already verified the existence of the
tp_as_buffer pointer).
Returns 0 on success and -1 (with an error raised) on
failure. This function always succeeds (as a NO-OP) if
there is no releasebuffer function for the object so that
it can always be called when the consumer is done with the
