[roll] Roll fuchsia [starnix] Don't use zxio for remote storage objects

+ This should save a fair bit of memory per node. Zxio storage is over
  250 bytes plus there are other overheads such as the overhead that
  comes with using `Arc`. This reduces nodes to 8 bytes and open files
  to 32 bytes. Both of these should end up in Scudo's smallest bucket,
  which is 32 bytes.

+ This significantly reduces the amount of unsafe code that remote
  objects will pass through. The only unsafe code that remains is the
  code that interfaces with InputBuffer and OutputBuffer.

+ Since this eliminates a layer, it is possible that this will improve
  performance. Some memory copying has been eliminated.

+ This will make it easier to add Starnix filesystem features in future
  because we will not necessarily have to update zxio first.

This CL includes some minor cleanups to the Fxfs verity implementation.

Integration

This repository contains Fuchsia's Global Integration manifest files.

Making changes

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.

Obtaining the source

First install Jiri.

Next run:

$ jiri init
$ jiri import minimal https://fuchsia.googlesource.com/integration
$ jiri update

Third party

Third party projects should have their own subdirectory in ./third_party.
