This change causes the generated abstract class having the same name as the interface to contain only the interface's method declarations. The generated Proxy class then implements the base class. In addition to implementing the interface methods, the generated Proxy class has one private field _proxyImpl, which is a MojoEventStreamListener and manages sending messages and receiving responses. Operations on the ProxyImpl (close, bind, etc.) are exposed through generated utility functions.
The generated Stub is largely as before with the difference that a class providing a service will implement the mojo interface and *have* a Stub rather than be a Stub. Where appropriate, this change also calls listen() immediately where a Stub is constructed.

I also fixed the transform hack in material-element to clean
up after itself.
I also discovered that our namedSetter implementation did not
handle null (it crashed) while doing this. I fixed that
and tested my fix.
This runs great on a Nexus 5, but poorly on an Nexus 10.

-Get rid of paintsWithTransform.
-Remove currentTransform. It was only ever called with
IncludeTransformOrigin and on non-null transforms.
-Remove renderableTransform. It was only called on
non-null transforms.
-Remove a layer()->parent() branch. The ASSERT had been
added in a previous patch, but the branch wasn't removed.
-Inline makeMatrixRenderable. It was only called in one
place.
-Add a test to make sure that transform origin is corrrectly
excluded from the transform computedStyle.

After this CL, you can use <sky-element> to describe custom elements. The
current iteration is very basic and is hardcoded to "example", but its a start.
This CL renames the |init| function to |_init| to prevent importers from
calling it directly. Also, we now pass the <script> element to |_init| to give
some context.

On the web, if you set position:absolute, but not
top/right/bottom/left, then the absolute goes where it
would have gone if it wasn't positioned. The use-cases for
this are slim and it introduces a lot of complexity to the
engine.
Also changes behavior in the presence of direction:rtl.
On the web, direction:rtl and top/left:auto would
sometimes set right:0. Instead we always position at
0,0 if the opposing values are auto.
This removes the code for this positioning and allows
simplifying a bunch of dirty bit handling code since
we don't need to setNeedsLayout if lines move around
or wrap differently.
The test cases did change their output, but the new
positioning all looks correct to me.

We only need to walk the immediate children of the paragraph.
The other inline children of the paragraph will get paint called
on them and they will then appropriately add the self painting
layers to the array inside their paint calls.

This CL implements custom elements. The design is as follows:
1) Authors subclass Element and call registerElement.
2) When we create C++ elements for custom elements, we call the author's
constructor synchronously.
3) The attach/detach/attributeChanged callbacks are called either:
a) when exiting the current custom element callback scoped (e.g., before
returning from appendChild), or
b) when draining the microtask queue.
The implementation in this CL is a bit fragile because we don't detect name
registration conflicts and we let you create custom elements with the same name
as built-in elements. Also, not every part of the engine is prepared to execute
script synchronously below createElement. We'll need to iron out these issues
over time, but this CL is a start.

This does several things:
1. Teaches sky about asynchronous script execution. Previously once all imports
were loaded and the script text was available, we executed a script and assumed
it completed synchronously. We left the parser loop to do so, but that was fine
as the next chunk from the background thread would resume the parser. In this
change scripts now load and execute separately. The "load" step may trigger
further dart import loads which may cause the execution to happen asynchronously
which required teaching both the DartController and the HTMLScriptRunner to
take callbacks to allow HTMLDocumentParser to know to continue parsing after
the Dart script has resolved its imports and executed.
This required re-working some of how the parser executes scripts and I
re-purposed isWaitingForScripts to include "is the parser blocked" where
as before it was limited only to "does the treebuilder have a script", even
though the imports system may have had pending scripts as well.
I made HTMLScriptRunner live only as long as the script it was executing
since it only contained per-script state at this point.
2. Fixed an error reporting bug whereby we would not show errors when "init"
failed to execute, only "main". This required using the dart_mirrors_api.h
which required adding an include path to the core build. :(
3. Made it possible for a single sky file to contain multiple dart <script>
tags. Each <script> is a separate library and executes as
soon as </script> is seen. main or init is called for each. This required
mangling "urls" for these script blocks since Dart unique's libraries by urls.
Before this change it may have been possible to do <import 'foo.sky'> and then
<script>import 'foo.sky'</script> and have it work!?

Change hit testing to walk over the render tree instead of
the RenderLayer tree. This is a step in the direction of
removing the RenderLayer tree entirely.
For now, there's a few calls back into RenderLayer that
will be removed in a followup patch. This patch also
breaks hit testing on transformed inlines. I'll be
removing the ability to transform inlines in a
followup patch anyways, so it's ok for hit testing
to give the wrong result temporarily here.
Almost all of this patch is just moving code from
RenderLayer to RenderBox. The primary substantive change
is in RenderBox::hitTestLayer. Instead of having
hitTestChildren calls, we call collectSelfPaintingLayers,
reverse sort by z-index (so we start at the top),
and then iterate over the result.
The test-case also exposes that we don't correctly hit
transformed elements inside inline-blocks. I went back as
far as 4153b8a515d54275934d4244aaf2d5a7a8fe3333 and the
bug still happened.

These now appear on internals as takeServicesProvidedToEmbedder and
takeServicesProvidedByEmbedder. When you call these functions, you get back the
raw int that represents the handle. We'll need to wrap them up inside the Dart
VM with the appropriate types. We can create a nice wrapper for that in a
future CL.

Because we dump dart errors to LOG(ERROR) (stderr) instead
of console.log / stdout, tests with dart errors just "pass"
and we don't notice they're not running.
This was the case with canvas-rounded-corners.sky.
I don't think this test actually passes yet, despite it
claiming to, but I at least have made it run and not crash.
Required me commenting out a ton of CanvasRenderingContext2D, but
that's fine, it wasn't actually working and it's better to have
it be compiling valid dart.

I'm not 100% what this was for, but looking at Blink,
it appears that HitTestChildBlockBackground being different
from HitTestBlockBackground had something to do with
multi-column/regions, which we don't have. I believe
this patch doesn't change any behavior.
Also added to the elementFromPoint test in order to
get more test coverage of the hitTesting code.

This CL removes a number of tests that we don't plan to port to Dart:
1) custom-elements. We're going to use a different mechanism for custom
elements. We'll need to write a new set of tests as we implement it.
2) inspector. These are tests of the JS inspector backend, which we don't
plan to use.
3) js. This is a test of a JavaScript feature.
4) mocha. These are tests of the JavaScript testing framework we were using.
5) mutation-observer. We're keeping the C++ code for mutation observers, but
it's unclear how we want to expose this in the platform.
6) resources. These are JavaScript-based testing frameworks.

Mostly just mechanical changes. The one surprising bit
is that RenderLayer no longer needs to explictly paint
outlines. I tested manually that before this patch,
the paintOutline call in RenderLayer was needed for
outlines on positioned elements and that after this
patch it's not.

This CL simplifies the sky_server to only map the build directory into /gen,
which will make the deploy script simpler. This CL updates all the imports to

Commit efc3afd428bd85fd3d12e0dc941b5eb7248ca30b broke it because
we'd computed an empty foreground layer. Now that background
painting is part of the foreground phase, we need to use the
background rect for clipping. As best I can tell, the
background rect is always >= the size of the foreground
rect, so it should be safe to use.

Instead of mojo.Shell and mojo.Application being clients of each other
they are now separate interfaces. An implementation of mojo.Application
receives a handle to the shell in its Initialize call, as described in
this doc:
https://docs.google.com/document/d/1xjt_TPjTu0elix8fNdBgWmnjJdJAtqSr1XDS_C-Ct8E/edit?usp=sharing
An analogous change is made to the content handler definition.
In C++, this is handled by the mojo::ApplicationImpl class which stores
shell handle in its implementation of Initialize. Thus the only change
for most C++ applications is the meaning of the handle in MojoMain is
different, although mains that use the ApplicationRunners do the same
thing with it. Connecting to other apps is largely the same although
instead of grabbing the ApplicationImpl's client() to talk to the shell
code must now use the ApplicationImpl::shell() getter.
In JavaScript, the initialization sequence is a bit different although
this is hidden mostly in the Application class which calls initialize()
on its subclass with the same set of parameters. Connecting to another
application looks different, especially for sky code using the shell
proxy handle exposed via internals. Hans has some ideas about how to
make this a bit nicer.
Python apps similarly need to change their startup sequence a bit. I
didn't find a common library to take care of this dance, although it's
possible I just missed it.
Other languages probably a bit of reworking - I fixed everything here
that is covered by mojob.py test but some might be missing.
This patch also uses typed handles (i.e. InterfacePtr<> or
InterfaceRequest<> or their type aliases) wherever possible instead of
ScopedMessagePipeHandle for clarity.
