Add a work in progress, a completely new, "Simple MPM".

The following MPMs currently exist:

  simple ........ Single or Multi Process, with Preforking or Threading,

                  depending on configuration and operating systems.  Should

                  be able to run on all modern operating systems.

  prefork ....... Multi  Process Model with Preforking (Apache 1.3)

  perchild ...... Multi  Process Model with Threading.

                  Constant number of processes, variable number of threads

The Simple MPM aims to create a single MPM, that runs on all modern

Unix and Win32 platforms, by using APR as much as possible.

The Simple MPM core run loop revovles around a Poll CB event system, with 

timers being built in.  When an event, either an IO or Timer is ready to run, 

it is dispatched to any available threads in the currrent process.
