[roll] Roll fuchsia [memory] Simulate pressure signals

Add support to the `mem` command to simulate memory pressure signals.
This just sends out the signals to all registered watchers of the
fuchsia.memorypressure service, without an associated memory growth. The
purpose of this option is to help watchers test their response to the
signals.

Expose a new internal service fuchsia.memory.Debugger hosted by
memory_monitor. This is a debug-only, Hub-published service, which the
`mem` tool talks to in order to simulate memory pressure signals. The
fuchsia.memory.Debugger protocol can be extended in the future for other
such diagnostic features.

Example usage: `mem --signal=CRITICAL`.
CRITICAL can be replaced with WARNING or NORMAL.

Test: memory_monitor_tests

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.
