FSO: Destroy observation if a directory watch's root disappears

When a disappeared event is received for a directory observation, we now
compare the incoming event's url against the observation scope's
`root_url`. When these match, we now send along the disappeared event
followed by an errored event. We then destruct the observation on the
browser process side.

Next up: A follow up CL will tackle parent directories being deleted
while we are observing a file.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure.

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
