This will replace the base/debug/crash_logging.h interface with an API
that is based off Crashpad's Annotations (https://crbug.com/crashpad/192).

Platforms that use Crashpad for crash reporting will indirectly use the
new Annotation API. Platforms still using Breakpad are provided a
source-compatible API that stores the data in the old NonAllocatingMap/
SimpleStringDictionary.

The InitializedArray template is courtesy of sdy@chromium.org.
