target: Fix incorrect strlen() NULL terminator checks
This patch fixes a number of cases in target core using an incorrectly
if (strlen(foo) > SOME_MAX_SIZE)
As strlen() returns the number of characters in the string not counting
the NULL character at the end. So if you do something like:
char buf[10];
if (strlen("0123456789") > 10)
return -ETOOLONG;
snprintf(buf, 10, "0123456789");
printf("%s\n", buf);
then the last "9" gets chopped off and only "012345678" is printed.
Plus I threw in one small related cleanup.
