[roll] Roll fuchsia [kernel][clock] Move clock reading code into libfasttime.

In preparation for allowing reads of memory mapped kernel clocks from
vDSO implementations (both the Fuchsia and Linux vDSO), move the
implementation of kernel clock reading code (backing zx_clock_read and
zx_clock_get_details) into libfasttime.  Then change the actual
in-kernel implementation to use this libfasttime version.

Sharing the code ensures that the kernel understanding of the internal
structures, and the vDSO understanding of the internal structures,
will remain the same, even if the structures are updated.

Additionally, putting the implementations into libfasttime makes it
easy for components such as Starnix to re-use the implementation for
their restricted mode clients.

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.
