eo - id lookup failure expansive error print for ebbter debug

whenan eoid lookup fails, now print a lot of information on the issue
like the actual id, generation of the id, if its a class or object
(the class bit), if its ref or super bit is set, the actual id (which
includes the table heirachy), which thread id it is, what domain the
object id is and the current and local domains as well as what domains
are mapped in.
