Subject: Update to 0.2.0: Add HandlerArray type.

  * Create HandlerArray as a safe wrapper around Handler.

  * Add Cargo features for HandlerArray size.

  * Move Handler into sub-module.

  * Add CriticalSection sub-module for architecture dependent support
    of interrupt-free contexts.

  * Add build rules to pull in cortex-m support for CriticalSection
    automatically.
