Blimp: create Mojo component for renderer/browser communication.

* Define new Mojo interface: "BlobChannelMojo".
* Add browser impl class "BlobChannelMojoImpl", add service registration
  logic.
* Add BlobChannelMojo connection code to BlimpContentRendererClient.
* Bifurcate ImageSerializationProcessor into client- and engine-specific
  versions. The engine specific portion is a client of the
  BlobChannelMojo service.
* Promote the skia, libwebp DEPS to the top-level of Blimp
  (blimp/client and blimp/engine will have their own
  ImageSerializationProcessor implementations.)
* Add new DEP for mojo.

Initial version of Blimp BlobCache.

Currently, every time there is a commit from engine to client, all
pictures are sent again, leading to poor performance and high
bandwidth usage.

This CL adds a cache on the client side that never clears out any
received resources. This means that the engine can depend on that
the client has all resources it has previously sent, and uses this fact
to only send down a unique identifier (SHA1 hash of the image) and the
the width and height in place of the image itself. This is wrapped in
the new proto BlobCacheImageMetadata. If this would be a new image for
the client, the proto also includes the payload of the image. This
payload will be removed when the BlobChannel is fully integrated.

The identifier is calculated based on the source image, to ensure that
no encode is required on the engine when the same image is seen again.

To ensure that the cache is used for all images, this changes the
behavior of the serializer to also encode images that were previously
encoded as WebP, to ensure that they become cacheable.

[blimp] Change to use SHA-256 instead of SHA-1 for unique ids

Blimp currently uses SHA-1 to uniquely identify resources. There was
no specific reason for this other than the goal of having a unique
ID, so this changes it to instead use SHA-256 from //crypto, since it
is in general better. This does however change the length of the
hash from 20 bytes to 32 bytes.

This concern was raised as a drive-by comment on
https://codereview.chromium.org/1867653002/

This CL also adds functionality to verify that a specific BlobId has
the correct length, and removes all references to SHA1 outside of
the //blimp/common/blob_cache/id_util.[cc|h] files.

In addition, this CL adds a test to ensure that there is certainty
that this unique ID only ever changes intentionally.

entries, or if they aren't available, issuing requests for the data to
a remote BlobChannelReceiver.

The transport-specific details are provided by a delegate object,
the implementation of which is out of scope for this CL.

Add a BlobCache mock class.

to connect the two together.

Also added:
* a string-based overload for CalculateBlobId();
* promoted CreateBlobDataPtr() to a common location.

This Blimp bug is targeted to M-52, which ends today.  Please change the target milestone to M-53 (which ends June 30) if appropriate and if your team lead signs off.  Any items still targeted to M-52 on Monday will have their milestone tags removed.

Please do *not* remove the label Blimp-M52-Proj-Scope if it exists on this bug; that is a scope tracking label only.  Similarly, do not add Blimp-M53-Proj-Scope yet either; I'll take care of that.

Ping me with any questions, thanks!

[Bulk edit]

Setting tracking label Blimp-M53-Proj-Scope.  This label is for scope tracking purposes only and should not be added / removed from any bugs, even if we add additional bugs to M-53 scope, or remove this bug from M-53 scope.

Blimp: Add BlobChannel Helium messages and delegate impls.

* Add BlobChannelMessage protobuf definition.
* Add prettyprint logging for BlobChannelMessage.
* Add CreateBlimpMessage specialization for BlobChannelMessage.
* Add targeted unit tests for new Helium delegates.
* Move BlobData constness into BlobDataPtr, so that BlobData objects are mutable following their creation (necessary for passing payload buffers w/o copies).
* Refactor CreateBlobDataPtr into common location.
* Turn BlobChannelReceiver into an abstract interface for testing, moving implementation to BlobChannelReceiverImpl.

Incorporate BlobChannel into Blimp image encode/decode pipeline.

* Add "BlobChannelSenderHost" class which encapsulates calls to Mojo
  and manages a renderer-resident copy of the cache state.
  Access to the cache state enables the renderer to avoid
  performing redundant operations such as resampling/transcoding
  if the data has previously been processed by another renderer.
* Modify Mojo interface to transmit blob payloads as strings,
  which is consistent with the C++ BlobData typedef.
* Remove BlobChannel/BlobCache calls from WebPDecoder (now it only
  decodes WebP images.)
* Make ClientImageSerializationProcessor into a singleton.
* Add getter path for BlobChannel sender for Engine browser process.

Excluding sharedmem and renderer cache state seeding from this bug, so everything is done. :)

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/27ea310df5b26c303575e1c7c401045e3f51f8af

commit 27ea310df5b26c303575e1c7c401045e3f51f8af
Author: kmarshall <kmarshall@chromium.org>
Date: Tue Jun 14 02:09:41 2016

Incorporate BlobChannel into Blimp image encode/decode pipeline.

* Add "BlobChannelSenderHost" class which encapsulates calls to Mojo
  and manages a renderer-resident copy of the cache state.
  Access to the cache state enables the renderer to avoid
  performing redundant operations such as resampling/transcoding
  if the data has previously been processed by another renderer.
* Modify Mojo interface to transmit blob payloads as strings,
  which is consistent with the C++ BlobData typedef.
* Remove BlobChannel/BlobCache calls from WebPDecoder (now it only
  decodes WebP images.)
* Make ClientImageSerializationProcessor into a singleton.
* Add getter path for BlobChannel sender for Engine browser process.

Use shared memory for moving data over BlobChannel Mojo interface.

* Change BlobChannel PutBlob() Mojo IDL to use shared memory handles
  instead of a byte array.
* Create "SharedMemoryBlob" class for encapsulating Mojo shared
  memory initialization and lifetime management semantics.
* Add BlobChannelSenderProxy class, which manages interactions with the renderer side of the BlobChannel IPC interface.
* Add Blimp-specific run_all_unittests.cc, which bootstraps the Mojo environment before executing unittests.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/2cfb64fdb531ebf178913ccda75d8b6954b9bae9

commit 2cfb64fdb531ebf178913ccda75d8b6954b9bae9
Author: kmarshall <kmarshall@chromium.org>
Date: Wed Jul 20 20:39:41 2016

Add Mojo IPC for seeding new Renderer with Browser's cached blob state.

Cache key state is currently stored in the renderer and is used
by the image processor to determine which images should be transcoded
and sent to the client, and which images do not need to be sent,
reducing latency and compute resources. A drawback of storing this
state in the renderer is that the cache state is dumped when the
renderer is torn down, as in the case when the user navigates
to another site.

This patch provides the renderer with a snapshot of the browser's
cache state, which means that the knowledge of cache state is
retained when the renderer of a given site is torn down
and brought back again.

* Add GetCacheState() to BlobCache
* Add GetCacheState() to BlobChannelSender()
* Add GetCacheState() to .mojom file.
