cc: Make sure resource pool releases its memory.

In the case where there are tasks scheduled to run and we enter
ALLOW_NOTHING mode, we would early out from DidFinishRunningTasks
and keep resources on tasks that were finished between the last schedule
and entering ALLOW_NOTHING mode.

Fix license header for third_party/readability

The format of the license field in
third_party/readability/README.chromium makes the license checker
erroneoulsy flag it as incompatible as it doesn't fit the regex.

Android WebView is now depending on third_party/readability (another
discussion perhaps) and there's no good reason to exclude it from
the WebView build right now.
