[roll] Roll fuchsia [starnix] Add tests for various `brk()` edge-cases

Verify that pre-existing mappings prevent `brk()` being grown.
Verify that mappings over the program break do not prevent it
being reduced.
Verify that the program break address is the first byte after the
program break, not part of it, such that if the address is aligned
then the page containing it is not accessible.
Verify that shrinking to an aligned break, and re-growing,
correctly allocates fresh program break pages.
Verify that mappings over the existing break region do not prevent
the break from being extended, and are not overwritten.

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.
