Replace first patch (which is not in master after nearly 4 years) with
a new set of pending patches to fix the following build failure with
gcc >= 7:
liboping.c: In function 'ping_set_ttl':
liboping.c:207:9: error: '%s' directive output may be truncated writing up to 255 bytes into a region of size 242 [-Werror=format-truncation=]
207 | "%s: %s", function, message);
| ^~
......
829 | sstrerror (ret, errbuf, sizeof (errbuf)));
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
liboping.c:206:2: note: 'snprintf' output between 15 and 270 bytes into a destination of size 256
206 | snprintf (obj->errmsg, sizeof (obj->errmsg),
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
207 | "%s: %s", function, message);
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
