[roll] Roll fuchsia [fxfs] Add support for write locks to LockManager

There are some operations that are going to require us to lock the
entire filesystem, e.g. fsck (although it might improve a bit if/when we
support snapshots).  For that, we need to support conventional write
locks (the locks used by transactions only block other writers, not
readers).

I also refactored this slightly so that there's only one lock function.

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.
