[roll] Roll fuchsia [starnix/usercopy] Return read & unread portions

...of the destination buffer from the `copyin` utilities.

The `copyin` utilities takes a destination buffer of uninitialized
bytes. To simplify later changes that write into uninitialized buffers,
return the portion of the destination buffer that has been successfully
copied to (initialized) and remaining (uninitialized).

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.
