[roll] Roll fuchsia [vfs] Change ExecutionScope to use fuchsia-async cancellation There are some changes in semantics: 1. Once shut down and the active-guard count reaches zero, it cannot be incremented again, which means that spawning new tasks when a future is dropped is no longer guaranteed to always run tasks. This has implications for Fxfs and flushing files. I had to rework the code to make sure files get flushed before Fxfs is shut down. 2. Tasks that are spawned no longer hold a reference to its scope, which means that the caller must retain the scope. 3. Tasks are no longer guaranteed to run at least once when spawned. We no longer seem to depend on this. Along the way, I spotted an issue with symlinks. They didn't have an open count so it was possible to unlink them and then you'd get errors if you tried to read the link. I've changed this to match what happens on Linux: you can continue to read the link until the symlink is closed.

This repository contains Fuchsia's Global Integration manifest files.
All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.
Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance in one of the communication channels documented at get involved.
First install Jiri.
Next run:
$ jiri init $ jiri import minimal https://fuchsia.googlesource.com/integration $ jiri update
Third party projects should have their own subdirectory in ./third_party.
