  1. Fallback to 256 w/ no host name max on unix 

    POSIX allows sysconf(_SC_HOST_NAME_MAX) to return -1 in case no limit
is set; in such cases, fallback to an hardcoded 256 as limit for the
buffer used for libc::gethostname(), which should be more than good
enough in most/all the cases.

This fixes gethostname() on GNU/Hurd, where there is no limit defined
by sysconf(_SC_HOST_NAME_MAX).
