This change makes IndexedDBFactory a virtual base class, and what was
IndexedDBFactory is now IndexedDBFactoryImpl. This change will allow tests
to create proper mock factories and not require them to instantiate the
"real" factory (which often doesn't work) in the test. It will also take us
one step closer to eliminating special cases in IDB's other classes where
having a factory is optional (because tests don't create them).

Adds support for non-blocking initial sync to the sync protocol.  This
allows some types to request an initial sync without having the
scheduler enter configure mode.  The protocol changes are necessary to
keep the server informed that the request is due to an initial sync
request.

The remainder of the changes in this CL were required to plumb
information about the cause of the sync cycle through the SyncScheduler.
This CL also includes some new tests.

At the moment, there are no types in use that support this feature.
This CL will not affect behavior in any way.

In preparation for migrating to TimeSource, StartPlayingFrom() is
renamed to StartPlaying() with renderers expected to fetch the current
time instead of being provided the time.

AudioRenderer::SetMediaTime() is temporarily added until we can migrate
the interface to being based on TimeSource.

Previously the GN Windows build specified the symbol file $pdbfile but this variable was never defined, so the command like would just say "/Fd" and the default one would be used.

This patch defines some per-target variables in the ninja file for the toolchain to use. The Windows toolchain uses these to construct C- and C++-specific pdb files (the MS tools can't share between these two) for the current target.

It did pass two runs, but is consistently failing now. So I'm not sure
whether this is a regression or flake. Since the test is so new, it seems
safest to just disable this page until it shakes out.

If this isn't a flake, the regression range is r283974-284019.

- Adds a positive test, where the owner logs-in while in safe mode.
- Fixes the test, where a non-owner tries to login: It failed because the MockOwnerKeyUtil had no key set. Now it fails because the private key cannot be found.
- Removes the ScopedTestNSSDB usage.
- Speeds up the test by factor 10, because of the removed NSS initialization in the test fixture.

This patch adds a layer level raster tile perftest to measure how
expensive is it to create a layer raster tile iterator.

NOTE TO PERF SHERIFFS

This patch replaces layer_raster_tile_iterator test with
layer_raster_tile_iterator_construct_and_iterate test.

In order for RenderPass to own allocation of DrawQuads and
SharedQuadState, update surface type converter code in mojo so when
convert to DrawQuad and SharedQuadState, function takes in pointer to RenderPass
as parameter. Also in unittest, create RenderPass to deal with DrawQuad and
SharedQuadState creation.

Make it possible for clients pass in a custom task runner to be used for
posting compositor related work onto the main thread. This will be used
for prioritizing compositor tasks by the Blink scheduler.

Covered by existing tests.
