Implement a new status function for ncbuf. It allows to quickly report if a buffer contains data in a fragmented way, i.e. with gaps in between or at start of the buffer. To summarize, a buffer is considered as non-fragmented in the following cases : - a null or empty buffer - a full buffer - a buffer containing exactly one data block at the beginning, following by a gap until the end.
