* thread_dbP.h (DB_FUNCTION): New macro.
* structs.def: Use it for __nptl_create_event and __nptl_death_event.
* db_info.c (DB_FUNCTION): New macro.
* td_symbol_list.c (DB_FUNCTION): New macro, prepend "." to symbol
name under [HAVE_ASM_GLOBAL_DOT_NAME].
(td_lookup) [HAVE_ASM_GLOBAL_DOT_NAME]: If lookup fails with PS_NOSYM
and name starts with a dot, try it without the dot.
