Refactor FileIO to the new resource host system.

Refactor FileIO to the new resource host system.
Taking over from Victor's CL: https://codereview.chromium.org/11419131/

Re-landing, with a fix. The original waited to reset the file state until
after the callback had completed. This is too late, as the client should be
able to perform another file operation during the callback.

Changeset #1 is the original patch. The fix is in change set #2

Julien for IPC review of ppapi_messages.h. You've already reviewed it and even
rubber stamped it once, this is a reland because we had to revert once.
