port/snprintf(): fix overflow and do padding
Prevent port/snprintf() from overflowing its local fixed-size buffer and pad to the desired number of digits with zeros, even if the precision is beyond the ability of the native sprintf(). port/snprintf() is only used on systems that lack a native snprintf(). Reported by Bruce Momjian. Patch by Tom Lane. Backpatch to all supported versions. Security: CVE-2015-0242
