[roll] Roll fuchsia [profiler] Added process watcher

This cl implements a process watcher for the cpu profiler. It enables it
to monitor a thread and be notified when a monitored process starts a
new thread so that we can monitor it as well.

Since we're now passing around an async dispatcher anyways, this cl
also moves away from sampling on a std::thread and instead samples using
the async loop. This simplifies some locking, since we'll now never access
the data members concurrently and I did not observe a performance
difference in sample overhead.

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.
