src, tools: Set/get timeout and get qos for flows

Receiver timeouts can now be set on a flow using the flow_set_timeout
function. Specifying NULL disables the timeout.  The flow_get_timeout
function gets the value for the timeout.

This commit also deprecates fcntl in favor of flow_get_flags and
flow_set_flags functions.

struct qos_spec is typedef'd as a qosspec_t.

The tools and cdap.c are updated to use the new API.

Fixes a bug in operf client where the client's writer thread wouldn't
cancel on SIGINT.
