[roll] Roll fuchsia [kernel] Teach thread/process about unified address spaces

Teaches the kernel how to use unified address spaces. This mainly boils
down to:
1. Replacing the `aspace()` method on `Thread` with an `active_aspace()`
   method that is only used when context switching.
2. Redirecting all fault handling to static methods on
   `Thread::Current`, which will then figure out which address space to
   use to resolve a fault. If such an address space is not found, or we
   don't have access to the address space that contains the address, the
   methods return `ZX_ERR_NOT_FOUND`.

In addition, `ProcessDispatcher::normal_aspace` is modified to return
the unified address space when one exists.

Note that this change should have no functional effect, as it just
plumbs the unified aspace when it exists, but does not create unified
address spaces.

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.
