xscope: update to 1.4.5.

Support for using inet_ntop() was originally added to support IPv6, and
only used for IPv6 addresses.  Two decades later, this interface is
ubiquitous and OS'es have starting marking the old interfaces as deprecated,
so this release changes to use the modern interface whenever we can now.
(Note that code included from xtrans will only use the modern interfaces
when IPv6 is disabled if building against xtrans 1.6.0 or later.)

Alan Coopersmith (5):
      Remove ifdefs checking for ultrix & hpux
      Use closefrom() if available
      InitializeFD: only define "i" if we're going to use it
      if inet_ntop() is available, use it for IPv4 addresses as well
      xscope 1.4.5
