Unbreak support for snapshots now that we have our offline Dart loader. Also,
wire up support for snapshots in sky_shell on Linux.

New asserts:
- verify that after layout, the size fits the constraints
- verify that after layout, the size isn't infinite
- verify that you don't set the size in performLayout() if you have
  sizedByParent set
- verify that nobody reads your size during layout except you, or your
  parent if they said parentUsesSize:true

Fixes some bugs found by those asserts:
- RenderBlock, RenderStack, and RenderScaffold were not always setting
  parentUsesSize correctly
- RenderScaffold was setting its slot entries to null rather than
  removing them when the slot went away, which led to null derefs in
  certain circumstances

Also, rename a local variable in RenderStack.performLayout() because
it was shadowing a variable on the object itself, which was really
confusing when I first tried to debug this function...

This CL makes it possible to run Sky apps offline by introducing new
DartLibraryProvider subclasses, specifically one that can load directly from
the file system. A future CL will expand this functionality to work with asset
bundles as well.

Currently, the only platform that uses this functionality is Linux, which can
now load a simple Sky app without even loading a network stack. Making this
work on other platforms is work for future CLs.

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...

WorkerPools can't be shut down, which means that the app's .so can't be
unloaded (which is bad for single process mode, and which is probably
why the asset bundle tests are flakily crashing on the try bots).

So use a SequencedWorkerPool instead (even though we don't care about
sequencing).

This CL factors the network interactions out of DartLoader into a
DartLibraryProvider interface, paving the way for other library providers
(e.g., offline).

As part of this CL, I've renamed DartLoader to DartLibraryLoader and moved the
class into tonic, where it can't have any direct network dependencies.

This CL adds the ability to load Dart snapshot files created by sky_packager in
Sky. Using a snapshot lets us transmit all the code for an app in a single blob
and should improve startup time. Later CLs will make this codepath easier to
use and evaluate performance.
