Signals were not a good choice of IPC to implement the poll function for several reasons: In order to handle the asynchrnous poll-related event, a substantial amount of state information is needed. Signals are only capable of passing minimal amounts of data. There are also complexities with performing kernel space signal handlers in kernel space code that is better to avoid. So, instead of signals, the equivalent logic was converted to run via a callback that executes on the high-priority work queue.

drivers/serial: Add support for Ctrl-Z. This works just like the recently added Ctrl-C support except that SIGSTP is sent when the Ctrl-Z characters is encountered vs. SIGINT.

sched/signal: Add a generic signal notification facility. Modify the custom IOB available notifier so that it is now just a wrapper around this generic signal notification. This generic signal notification faility will, eventually, be used to support network polling.
