nptl: Move __nptl_create_event, __nptl_death_event into libc
In libthread_db, use the exported GLIBC_PRIVATE symbols directly instead of relying on _thread_db_* variables in libpthread (which used to be created by the DB_FUNCTION macros). Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
