A recurring problem, mainly on the BSD's, and also on some Linux installations, is a failure for ttsession to start and any clients trying to attach to it failing due to having a hostname that is not associated with an IP address. This is due to code which looks up the hostname, and if it does not have a valid host record, then TT just fails. This has required those users to add an alias for their host name in their /etc/hosts file. With this commit, this should no longer be necessary. Now, if _XGethostbyname() fails when looking up the local name, a default of "localhost" is used, which should always exist. This was run tested on Linux and FreeBSD 11.1. It was compile tested on OpenBSD 6.2.
