BUG/MEDIUM: ncbuf: fix null buffer usage

ncbuf public API functions were not ready to deal with a NCBUF_NULL as
parameter. Strenghten these functions by handling it properly.

Most of the functions will consider the buffer as empty and silently
returns. The only exception is ncb_init(buf) which cannot be called
with a NCBUF_NULL. This seems legitimate to consider this as a bug and
not silently failed in this case.
