curl_gethost() potential bug fixups
This is in the realm of "probably not going to happen", but if someone were to translate "disk" to a string longer than 256 characters, we would have a smashed/corrupted stack due to our unchecked strcpy() call. Rework the function to always length-check the value we copy into the hostname buffer, and do it with memcpy rather than the more cumbersome and unnecessary snprintf. Finally, move the magic 256 value into a constant and pass it into the function which is going to get inlined anyway. Signed-off-by: Dan McGee <dan@archlinux.org>
