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.
