> A bunch of remaining parts of extension content verification

> -The real guts of content_hash_fetcher.cc, which fetches the

>  tasks to compute and cache the block-level hashes of all files in an
>  extension.
> 
> -The real guts of content_hash_reader.cc, which uses the work done by

> -Code to avoid verifying transcoded files (images used in browser
