core: Silence newer compiler warnings.
* configure.ac: Add -Wno-format-truncation and
-Wno-sizeof-pointer-div.
* src/b64dec.c (_gpgme_b64dec_proc): Add fallthrough annotation.
* src/cJSON.c (parse_string): Ditto.
* src/gpgme-json.c (main): Ditto.

gcc 8 enables a couple of new warnings. Some of them are useless for
us. In particular:
util.h:42:26: warning: division 'sizeof (char *) / sizeof (char)'
does not compute the number of array elements [-Wsizeof-pointer-div]
#define DIM(v) (sizeof(v)/sizeof((v)[0])) ^
trustlist.c:101:22: note:
in expansion of macro 'DIM' if (strlen (p) == DIM(item->keyid) - 1)
Which is a real standard way to use DIM, here the right hand side is
equivalent to sizeof but nevertheless it is correct. Yes sir, we know
C.
The format string warnings I have seen were assuming that the time
structure returns valued out of scope - but if the system is that
broken, the s_n_printf catches this.
