* Asynchronous network IO subsystem

- This is now implemented such that it very nearly only depends on the platform
  code (Socker & Poller), this is not 100% true at present, but should be simple
  to finish.
- This is still not the default (use "./configure --disable-apr-netio" to get it)
- Interrupting the broker gives a known error
- Default for number of broker io threads is not correct (needs to be number of CPUs -
  it will run slower with too many io threads)

* EventChannel code
- Deleted all EventChannel code as it's entirely superceded by this new shiny code ;-)

* Rearranged the platform Socket implementations a bit for better abstraction
