Add Angus Gratton's AVR extra functions

[GoogleCodeExporter]

On 2010/06/28, from Angus Gratton on the maillist:

3) avr_extra_functions.patch

I extended the existing avr.py with some new functions. There are now 
Arduino-style avr.digitalRead(PORT, PIN) and avr.digitalWrite(PORT, PIN, value) 
methods to read/write single pins.

Also, new avr.ddrA(VAL) to set DDRA register and avr.PORTA() now works 
correctly for reading pin values as well as writing them (I could only get 
writes to work with the old module.)

There are also avr.ddrX and avr.portX functions for all of the other ports 
(B-F) but they are commented out in the Python source because all of those 
extra functions use a bunch of RAM when the module imports - so for now you 
need to comment them in if you want to use each one.

r570
- Applied the patch
- Renamed sleepMs() to delay() because MCU was not put in sleep mode
- Rewrote platform/avr/main.py to be more python-like
- Wrapped PINC ... PINF with #ifdefs because not all MCUs have those ports 
(would result in compile error).

Builds w/o error.  Too lazy to test on device.
Mainlined directly
