* Add poll() and select() APIs (in the initial check-in, these work only with character devices)
* Add poll() methods to /dev/null, /dev/zero, pipes, fifos, and serial drivers.
* Add examples/poll for testing poll() and select()
* Fix hostile behavior of getc, fgetc, getchar, etc.: the serial driver was waiting for a
full buffer of read data before return. This means that getc would stall when it needed
to refill the input buffer. The old behavior (read full blocks) might be useful in other
contexts, so it is still available within the driver as a configuration option.
