Replace the RenderProcessHost.PID function that returns the OS-generated
process ID with an internally-generated id() function. This allows us the
guarantee that the IDs are unique over the entire run of the application.
This also cleans up some code associated with managing the PID.
The main potentially interesting change is now the PID is set uniquely for
every creation of RenderProcessHost. It used to be set cleared if the process
went away, and re-set if the process was re-created. The ID generation is in
ChildProcesInfo so it is also unique between workers and plugins. I had to
change some significant things in resource_dispatcher_host_unittest to take
into account this new generation of IDs.
