This also fixes the C++ side to give the right baseline information.
Previously it was giving the baseline distance for the font, but not
for the actual laid-out text.
I considered also providing a "defaultBaseline" accessor that returns
the distance for the actual dominant baseline, but it turns out right
now we never decide the baseline is ideographic. We always use the
alphabetic baseline. We should probably fix that...

This file doesn't belong in the SDK because it is an implementation detail of
the Sky engine. Instead, this CL moves the code for dart:sky.internals into the
snapshot. This CL is a step towards merging dart:sky.internals with dart:sky,
which also resides in the snapshot.

The relayout subtree root concept is intended to handle the case where
a node, when it lays itself out for a second time, changes its opinion
about what dimensions it should be. In such a situation, the parent,
if it based its own opinion about what size _it_ should be on the
child's dimensions, would also need to lay itself out again. Thus,
when this scenario is possible, the child remembers the parent, and
when it would be told to relayout, we actually start the layout with
the parent.
In practice, this chains, and we end up with nodes that point to
ancestors ten or more steps up the tree such that when the inner most
child re-lays-out, the whole app ends up relaying out.
This patch tries to short-circuit this for the case where the
constraints being applied to the child are such that actually, the
child has no choice about its dimensions. In that case, the parent
can't change dimensions when the child re-lays-out.
This makes a huge difference on the stocks demo app. Without this, on
the third rendered frame, there are 72 relayoutSubtreeRoot links, the
deepest chain is 8 deep, and 9 of the chains are only 1 level deep.
With it, there are 63 relayoutSubtreeRoot links, the deepest chain is
only 4 deep, and 38 of the chains are only 1 level deep.

Update sky_server:
- update its help string to admit that it wants the package path as well.
- be quiet by default, since it makes the build chatty.
- have a -v for verbose mode, for people who like it chatty.
- have a default port of 8000, since that's what everyone used.
- have a -p option to set the port, for people who don't use the default.
- remove its mapping for gen/, since a TODO told me to.
- remove the dependency on the build configuration, since it's no longer used.
- teach it about .dart files.
- rename sky_server/README to README.md, for consistency with other READMEs.
Update shelldb to speak the new sky_server protocol.
Update tests/services/iframe-embed-vmc.sky since the sky_server change broke the hack it was using.
Update skyserver.py to speak the new sky_server protocol.
Make webkitpy use SkyServer instead of spawning sky_server itself, since a TODO told me to.
Teach webkitpy about dart files.
Teach test_perf about dart files. (untested)
Teach sky_tool about main.dart, main.sky is deprecated. (untested)

We're now 25% faster as scrolling the infinite list than stocks1.
This CL makes cleans up some code to avoid calling layout on all the rows in
the stocks list. Instead, we only layout a row when it first enters the list.

Ok, not really zero. Actually 72 if you include warnings from non-sky packages and if you include bogus warnings that can be filtered out.
If you pipe the analyzer's output through the following perl script, though, you get zero warnings on the stock app with this patch:
while (defined($_ = <STDIN>)) {
s|out/android_Debug/gen/dart-pkg/sky/|sky/sdk/|gos;
next if m|/dart-pkg/|os; # other packages
next if m|^\[warning] Missing concrete implementation of 'RenderObject.toString'|os; # https://github.com/dart-lang/sdk/issues/23606
print;
}

Currently you lose your scroll and drawer state when coming back from the settings pane.
I think we should solve this by having the Navigator maintain a Stack and
keeping the StockHome alive underneath it. But this is good enough for a first iteration.

tree of InlineStyle and InlineText elements.
StyledText builds an Inline that renders the tree.
For example this StyledText object:
new StyledText(["FOO", [boldLargerStyle, [greenStyle "BAR"], "BAZ"] BORF]);
Renders the same way the following HTML would,
assuming that TextStyles boldLargerStyle and
greenStyle were defined.
<style>
div {
display: inline;
}
</style>
<p>
<div>
FOO
<div style="font-weight:bold; font-size:larger">
<div style="color:green">
BAR
</div>
BAZ
</div>
BORF

We can't have two copies of |embedder.dart| or |shell.dart| because they take
ownership of some underlying Mojo handles. Instead of duplicating the code,
this CL makes the old locations just export all the symbols from the new
location. I've also done the same with fetch.dart to avoid code duplication.
Finally, I've removed image_cache.dart in the old location because the only
clients already live in the new world and ought to use the new location.

Some files are moved by this:
Copy framework/node.dart into types/ - preparing for framework/'s decomissioning.
Move app/scheduler.dart into sky/scheduler.dart - "app" doesn't really make sense.
As part of the SkyBinding cleanup, I made the hit-testing less
RenderBox-specific, by having the HitTestEntry.target member be a
HitTestTarget, which is an interface with the handleEvent() function,
which is then implemented by RenderBox. In theory, someone could now
extend hit testing from the RenderBox world into their own tree of
nodes, and take part in all the same dispatch logic automatically.
This involved moving all the hit testing type definitions into a new
sky/hittest.dart file.
Renamed SkyBinding._app to SkyBinding._instance for clarity.
Moved code around in SkyBinding so that related things are together.
Made WidgetSkyBinding use the existing SkyBinding.instance singleton
logic rather than having its own copy.
I also added some stub README.md files that describe dependencies.

Move app/view.dart to rendering/sky_binding.dart since it's part of the RenderObject API, really (it knows about RenderView intimately).
The tests pass. I didn't check every last example.

Buttons and menu items use onPressed. Also, don't pass along the sky.Event
because that's a lower-level concept.
I've also reordered parameter lists to put the |child| argument last in a
number of places.
Also, fixed a bug where FloatingActionButton was missing syncFields.
