264: Add support for AVR. r=japaric a=jeremysalwen

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

 - AVR was added to the list of architectures not supporting atomics or cas.
 - AVR was configured to not use AtomicUsize, similarly to armv6m.
 - SortedLinkedList was modified to account for the fact that usize is differently sized on
   different architectures (16 bits on AVR).
