[roll] Roll fuchsia [pkg-cache] Implement NeededBlobs::GetMissingBlobs

This change implements the next step of the NeededBlobs protocol and
adds some helper mocks for the pkgfs client lib to serve the
/pkgfs/needs directory.

At this point, clients can open/write the meta FAR and discover needed
contents blobs using the GetMissingBlobs() request and BlobInfoIterator
provided by pkg-cache. The current implementation uses
/pkgfs/needs/<meta_far_merkle> to determine the needed blobs for a
package after the meta FAR is written.  Future work will migrate
pkg-cache to parse the package metadata directly to determine which
blobs are still needed.

Next up, implement opening/writing the content blobs.

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.
