[PATCH] ioctl compatibility for TIOCMIWAIT and TIOCGICOUNT

This patch lets us use TIOCMIWAIT and TIOCGICOUNT from a 32-bit process on
a 64-bit processor.  TIOCMIWAIT uses the argument as a bitmap of things to
wait for.  The argument for TIOCGICOUNT points to a struct
serial_icounter_struct, which only contains ints and arrays of int.
