In a paragraph with a trailing newline, the width of the newline
character was included in the line width for breaking purposes,
basically as if it were a non-breaking space. This caused a
discrepancy, where Layout.getDesiredWidth() suggested that the text
would fit in a single line, but StaticLayout would break it because of
the added width of the newline character.
The proposed fix is simply to consider newline to be a space that
disappears at the end of a line.

At present there is a special case in Dart bindings generation which
makes the Mojo SDK and things under mojo/services portable. However,
we must not require things under mojo/services to be next to the
Mojo SDK under mojo/public/... in client repos. Further, other
collections of mojoms should also be portable.
To fix this, instead of using the path in the host repo as the
canonical package: import URI for the generated Dart code, this CL
uses the mojom module name.

The name "margin" conflicts with another meaning, so we're making the
name in the public api "idents" and the code consistent in naming.

In order to support layout in non-rectangular regions, the LineWidths
object needs to accept an arbitrary array of margins. This is
implemented in addition to the existing firstWidthLineCount/restWidth
mechanism for convenience, though using only arrays would have the
same expressive power.

If your layout manager changes, then you need to setNeedsLayout,
otherwise the next frame doesn't even get scheduled. We already
correctly handle going from not having layout to having one or
vice versa by doing the more drastic reattaching since that
requires changing your actual render class.

We weren't correctly marking an element as needing style
recalc if it was *losing* it's layout manager. We were
only doing so when it was gaining a layout manager for
the first time.

Having the output of the tracing service be a list of json objects
instead of one json object makes it much easier to combine multiple
sources. This teaches skydb (which wants to format the output into a
json file loadable by trace-viewer) to emit the tracing header/footer
itself. This will make it possible to combine data from the tracing
service with data collected by the shell itself.

Text can only only inside paragraphs and inlines. This patch makes it
so we stop putting such text nodes in the render tree at all if their
parent is not a paragraph or an inline.
This is the final step in making it so that we don't create anonymous
renderers, which fixes a crash in the new custom layout code.

We only ever create RenderParagraphs now. The only non-trivial change here
is making RenderView a RenderFlexibleBox. This required changing custom.sky.
That test was written in a fragile way that behaved differently if we
did multiple layouts. Instead, having it be less racy and only change
values during the test itself.
This also throws a wrench in moving all the layout code to dart
because we can't set the layout manager on the RenderView. Maybe
we need to explicitly let you do so.

-Make display:flex, flex-direction: column, flex-shrink: 1 the default.
-Simplify StyleAdjuster::adjustStyleForAlignment to remove special cases we
won't need as we make flex the default and remove absolute positioning.
-Fix a bug this exposed in column flexboxes where we'd apply the wrong edge
of border/padding/margin.
-For now leave the default of align-items:stretch. The main change here is
that iframe/img will do width:auto the same as blocks (i.e. the width of
the parent). I think this is a good change, but we'll have to see how it feels
in practice.

This flag to mojo_shell is gaining the ability to produce tracing info
starting very early in process startup. This allows the skydb 'start'
command to pass this command through to mojo_shell.

-Temporarily add setting override width as well so that we correctly bypass in RenderBox::computeLogicalWidth.
-Add setNeedsLayout so that the author code can force layouts (e.g. when the container's width changes).
-Have setLayoutManager force a reattach of the element if it's renderer wasn't a custom layout one before.
-Remove the laying out of children from RenderCustomLayout::layout. This is the job of the author code.
-Add a test case.

This patch adds hyphenation using the Liang hyphenation algorithm,
similar to TeX. It also improves the optimized line breaker so that
it works correctly and efficiently even when the line width is not
constant (there is a specialization for constant width, which is
probably worthwhile, but performance TODOs remain).
Still to be done:
* hyphenator has many shortcuts, only tested with English
* interaction between punctuation and hyphenation is problematic

This patch adds a LineBreaker class to Minikin, which will be used for
computing line breaks in StaticLayout. The version in this patch
contains basically the same functionality that existed before, but
hopefully better performance and an interface that's suitable for more
sophisticated paragraph layout.
Note that this version contains a high quality strategy, which mostly
works but doesn't respect varying line width.

It's especially crappy since it doesn't actually do much/any error
handling.
Use:
$ sky/tools/skydb start out/Debug \
'sky/examples/terminal/index.sky?url=mojo:netcat?host=localhost%26port=80'
(Note: We don't have a resolver yet, so the host either has to be
"localhost" or an IPv4 address in the form N1.N2.N3.N4.)

The bindings, core, and application libraries are now referred to as, e.g.:
package:mojo/public/dart/core.dart
Since the handle watcher remains in the snapshot, it no
longer refers to types defined in core.dart. References to types defined
in core.dart are also removed from mojo_natives.cc.
In Dart packaged apps, the SDK is zipped up under mojo/public/dart.
For embedder tests, the SDK is copied into the generated source output directory.
A base_dir parameter is added to the 'dart_package' and 'mojom' GN macros so that
consumers of the Mojo SDK can all import using the same URIs regardless of where
the SDK lives in their source trees.
