write() and print() should return number of bytes written (or indicate that an error occurred).

[GoogleCodeExporter]

The Print class write(), print(), and println() functions should return an 
number that indicates the number of bytes written, or indicate error.  Probably 
-1 should be used for errors, as there may be situations in which zero bytes 
were written but no error occurred (e.g. print("")).

I think we want a signed long, so print("") can return 0 and an error can 
return -1.  println() should return two (carriage return and newline).
