Instead of driving event dispatching through a per winsys poll_dispatch vfunc its now possible to associate a check and dispatch function with each file descriptor that is registered for polling. This means we can remove the winsys get_dispatch_timeout and poll_dispatch vfuncs and it also makes it easier for more orthogonal internal components to add file descriptors for polling to the mainloop.
