Refactor the process model code to allow the addition of a prefork
process model.
- Add a process context to contain process model specific state
- Add a service details structure to allow service to indicate which
process model options they can support.
In the new code the services advertise the features they support to the
process model. The process model context is plumbed through to allow the
process model to keep track of the supported options, and any state
the process model may require.
