- Introduced the use of gethostbyname_r() if available. As siproxd

uses threads it probably is a very good idea (some funny things
  seen with Linux 2.4.18 kernel & RTP proxy - gethostbyname()
  did return a NULL result but has h_errno set to 0 "every fine, thanks")
  Future will show it this helps.
- Had overlooked one inet_aton in register.c - replaced to utils_inet_aton
- Fixed a compiler warning in log.c for Solaris. Siproxd now at least
  builds on Solaris (tested on: SunOS 5.9 sun4u sparc SUNW,Ultra-60)
