At plenty of places we need to manipulate the conn_stream's endpoint just to set or clear a flag. This patch adds a handful of functions to perform the common operations (clr/set/get etc) on these flags at both the endpoint and at the conn_stream level. The functions were named after the target names, i.e. se_fl_*() to act on the stream endpoint flags, and sc_ep_* to manipulate the endpoint flags from the stream connector (currently conn_stream). For now they're not used.
