A bug in supervisor:get_childspec/2 results in
{error, simple_one_for_one} being returned on every call when the

Several people have requested that the assert macros in EUnit should be
moved out to a separate header file. This patch puts them in

Thus, nothing changes for eunit users, but the asserts can now also be
included separately.
