HostDBHash::set_host(): null termination (and lifetime) of string parameter ambiguous.

[ywkaras]

The prototype, https://github.com/apache/trafficserver/blob/bfd5265fd21b45c5fff0affdf8a3b88330d8181a/iocore/hostdb/HostDB.cc#L172 , implies the string is not null terminated. But it seems to assume the string is null terminated. in line 180.

We also seem to be sending a pointer to a string into deep call stacks and multiple source files, with no clear mechanism to guarantee that it doesn't go stale.
