r335: added much better handling of servers that die unexpectedly during a
request (a dead socket). I discovered this when testing against Sun's PC-NetLink. cleaned up the naming of some of the samr requests add IDL and test code for samr_QueryGroupMember(), samr_SetMemberAttributesOfGroup() and samr_Shutdown(). (actually, I didn't leave the samr_Shutdown() test in, as its fatal to windows servers due to doing exactly what it says it does).
