Add error checking to locate_host() and return truncated host name rather than
blank.
Encountered core dump from getnameinfo() during DOS attack. From dump, looked
like getpeername()
must have errored and address data was corupted.
When the return buffer for getnameinfo() is too small or errors, the function
does not put anything into the buffer.
Switched to using a large buffer and then copying so it should never truncate
and am able to copy truncated name.
