Subject: parser - use DUP_STRING more widely and detect strdup errors

Browse Source 
This patch moves the DUP_STRING macro to parser.h and modifies
it to accept a goto error target, that will be jumped to if the
call to strdup(3) fails. It also uses it in additional locations
where copying structures occurs, as well as detecting additional
cases where a structure duplication might have failed but not been
propagated outward.
