[roll] Roll fuchsia [netstack] Benchmark socket API with fake netstack

Add a variant of the socket benchmarks that runs against a "fake
netstack", which does the minimum possible amount of work to implement
the subset of the `fuchsia.posix.socket/Provider` protocol needed for
the benchmarks.

By comparing with the same benchmarks for the production netstack, this
will give us a signal about how much of the latency in e.g. UDP is due
to work done in the core netstack vs. due to the overhead of the API
(IPC, kernel roundtrips, FIDL de/serialization, etc.).

The fake netstack currently implements support for UDP and ICMP echo
sockets. Support for TCP and potentially "Fast UDP" will be implemented
in future changes.

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.
