Back in 2012 content/*/file_system was renamed to fileapi to contain both the code for the filesystem API and the blob system (i.e. the file API). However since then the blob system moved out to separate directories, so now we have the confusing situation that we have directories named after one API that contain the implementation of a different API.

We should rename content/browser/fileapi, storage/browser/fileapi and storage/common/fileapi back to filesystem to actually match what is in these directories and hopefully reduce confusion.
