added a short delay and comment to boolean operator in CDC
...
Delay fixes problem where the port has been configured but not quite opened. Federico found that 10 ms was the minimum time needed to avoid problems.

added Boolean operators to HardwareSerial and CDC to test whether the port is ready to send data.
...
Mostly useful for Leonardo - simple way to test whether the port is actually opened by an application and ready to receive data. For Serial objects attached to real UARTs always returns true.

reduced delay before starting the Leonardo bootloader
...
Since we use a magic RAM flag to signal to the bootloader there's a risk of the sketch overwriting the magic RAM location before the bootloader starts. By reducing the watchdog timeout we reduce the chance of this happening.

Leonardo now checks whether bootloader should be run after a WDT event.
...
Before the sketch initiates an auto-reset for upload it pokes a magic word into a specific RAM address. On starting the bootloader checks this address. If it finds the magic word it knows the bootloader code should run. If not it jumps straight back to sketch.
Test in a sketch by adding to setup():
wdt_enable(WDTO_2S);
Sketch should upload, start, run for two seconds, WDT, and sketch should restart (not bootloader).
Had to cut out unused descriptor code to make the bootloader still fit in 4k.

Leonardo auto-reset-and-upload changes for Windows (explanation below)
...
On Windows COM port changes when board switched between bootloader and sketch. No way to prevent this so now Windows users have to select the upload port separate from the comm port. Also, handling of reset into bootloader was broken on Windows. Would occasionally leave the original COM port completely unusable. Changed the way this reset is initiated.
Finally, had to add upload.disable.flushing=true flag to boards.txt so IDE wouldn't try to flush the original COM port after it disappeared.
