src/lib/libc/stdio: fread.3 fread.c fwrite.c
Log Message:
for fread(3) and fwrite(3) check for (size * nmemb) size_t overflow, and
error out with EOVERFLOW if it happens; this is less silly answer
to a silly call than returning some randomly wrapped length
change adapted from OpenBSD
FreeBSD has a similar check, but they return EINVAL instead, feel
free to adjust if SUS or other standard mandates specific value
