*	nbd: add tracepoints for send/receive timing	Andrew Hall	2019-04-26	1	-0/+51
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	This adds four tracepoints to nbd, enabling separate tracing of payload and header sending/receipt. In the send path for headers that have already been sent, we also explicitly initialize the handle so it can be referenced by the later tracepoint.

*	nbd: trace sending nbd requests	Matt Mullins	2019-04-26	1	-0/+56
	This adds a tracepoint that can both observe the nbd request being sent to the server, as well as modify that request , e.g., setting a flag in the request that will cause the server to collect detailed tracing data. The struct request * being handled is included to permit correlation with the block tracepoints.
