* Split apart platform (threading etc.) from network io

  you can now use a posix platform implementation by configuring
  --disable-apr-platform
* Changed Time classes to distinguish between absolute times (AbsTime)
  and durations (Duration). This should avoid bugs caused by confusing
  the two types of time.
