(ccalloc): Only issue system_printf when debugging.
* dtable.cc (dtable::extend): Only allocate 100 * the incremental growth size
max.  Set errno appropriately.
(dtable::build_fhandler): Check for error from set_name.
* fhandler.cc (fhandler_base::set_name): Set errno and return error on OOM.
* fhandler.h (fhandler_base::set_name): Change to bool.
* fhandler_process.cc (format_process_stat): Fix formatting.
* resource.cc (getrlimit): Return greater of OPEN_MAX or fd table size.
