make the C code call a Python function instead of Python polling a C function for new button events

Hi Lucas,
could you please update the C-file with following:

• There is an error when the former text is longer as new text. The rest of old text stays on display.
  Happens for example on book when "performance" isn't completely deleted.
• dgt3000Init() should return negative error code (to be consistent with the other functions). Also should be 2 different error codes.
• dgt3000Init() shouldn't do printf on errors. Please put the preprocessor command around it (like the other functions). Same for dgt3000Receive()

Create some code to give startup feedback before loading the kernel.

A virtual shutdown or standby option is needed to be able to turn the pi on and off safely with clock buttons. Going down to single user mode is probably the safest way to ensure the SD-card is no longer written to while still being able to check for clock buttons.

Hi Lucas,
i uploaded a new ctypestest.py file.

But for me, the "EndDisplay" is not 100% fully working.
Sometimes, i have to press the button many times until the clock display comes back.
Can y take a look?

To simplify the .h file and prevent accidental use of hi level functions split them into private high level functions and public low level functions. (in two .h files)
Also send the most detailed error code back for logging and debugging. (not "failed three times" but why it failed (the third time))

When expecting a Ack -> check often / immediately.
otherwise 1000/sec
