pgm_read_word() was already defined, but pgm_read_dword() did not
get in our way during earlier testing. These functions force the
arduino to read these "defined in program" constant arrays from
"program memory" instead of RAM as a means to save on RAM usage.
The PC-based simulator doesn't need such tricks and only needs to
read the value directly from the in-RAM array. Therefore it is safe
to convert read directly from the pointer being passed.
pgm_read_word() already does this. Define pgm_read_dword()
similarly to it. Fixes#125.
