Robert Bragg 95a41e177a Associate check and dispatch funcs with poll fds
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.
