[roll] Roll fuchsia [fxfs] Manage volumes explicitly on the client

Lifts the responsibility of creating the default volume to the client.
For now, we bake it into fs_management and fshost to always do this, so
this is generally a pure refactoring in terms of external behaviours.

That said, this involves a sweeping change to fs_management and all
clients thereof.  This is centered around the introduction of volume
management to fs_management, via:
- StartedMultiVolumeFilesystem in C++, and
- ServingMultiVoluemFilesystem in Rust.

A few other changes are made:
- migrate_root is no longer used and can be removed in a followup CL.
- Fxfs no longer implements request queueing, this is done by
  fshost anyways.
- Some minor adjustments are made to the export root layout, e.g.
  volumes export a svc/ directory.
- A number of minor bugs were fixed, e.g. swallowing errors during
  start (cf. fxrev.dev/702516) and the fs-management minfs tests
  not actually launching a componentized minfs when they say they do.

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 via the IRC channel #fuchsia on Freenode.

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.
