. Rename our internal gethostby{name,addr}_r functions to avoid collisions.

  Currently gethostbyaddr_r collides with the implementation (in libc!) for
  FreeBSD 5.x which both uses a different prototype (as per the Linux
  version) and is marked temporary and not thread safe.  Also, limit the
  scope of these internal implementations to this file.

  This fixes crashes in networked applications for FreeBSD 5.x.

  Some tweaks (making the functions static, naming, BSD ifdefs) by me.
