Add support for AVR.

Browse Source 
In order to support AVR, the following changes were made:

 - AVR was added to the list of architectures supported by atomic-polyfill.
 - SortedLinkedList was modified to account for the fact that usize is
   differently sized on different architectures (16 bits on AVR).
