The previous implementation was finding the form and field of the
select element that was modified for each option added or removed.

Since this can happen several times in a row it was not efficient.

This search now happens after all the add/remove have been debounced.

This uses the new TextureLayer APIs to register SharedBitmapIds instead
of using ClientSharedBitmapManager, in order to get the registration in
the same IPC channel that the compositor uses for submitting frames
that include the ImageLayerBridge's shared memory bitmaps.

This CL also fixes a bug where bitmap data wasn't properly copied into
shared memory. All rows from the source were copied into the same row of
the destination. This was causing the canvas to appear (almost?) all
black when using software compositing. I've tested the fix with
https://codepen.io/anon/pen/qoeQEE which looks the same using GPU and
software compositing.

The omnibox is a text element that updates according to user input.
User input happens after element layout, and since the text texture
heavily relies on layout, "dirtying" the text texture really means
laying it out again.

Prior to recent cleanup and refactoring, we mistakenly got away with
this - a text element could resize itself after the layout stage and
appear incorrectly.  Post-cleanup, the re-layout can't happen, but a new
bug was introduced where a post-layout phase could dirty a texture, and
the texture update phase would redraw and "clean" the texture without
doing layout.  The broken layout would then persist indefinitely.

To address the problem, elements may mark themselves as requiring
measurement for texture draw.  These elements will not be redrawn unless
their measurement step has happened.

There was a measured() DCHECK mechanism previously, that was taken out
because most textures no longer measure themselves.  This change
reintroduces that check in it's new form.

This is really what we ought to be doing to avoid ODR violations
caused by linking the prebuilt .a into multiple components, but
I previously couldn't see a way to link the .a into the component
.so with --whole-archive. However, it turns out that it's possible
using ldflags. This is a little hackish but it's probably better than
dealing with ODR violations.

It's possible to URLLoader to have a posted ReadMore task when it
learns its producer data pipe has been closed. If this happens, when
ReadMore is executed, it would DCHECK, since reading from a pipe a
consumer knows is closed it a possible symptom of a bug.

This CL fixes that behavior, by deleting the URLLoader when either the
data pipe or the client pipe is closed, or when the request is
complete, rather than waiting for both consumer pipes to be closed.

As described in the design doc ([1], accessible for Google employees
only), the proposed bridge integrates all relevant classes for syncing
sessions and exposes a USS API for a processor to use. This includes
propagating local changes to the server, as well as receiving remote
updates for foreign sessions.

The class is analogous to SessionsSyncManager and implements similar
logic, although many bits are handled in SessionStore (preceding
patch) to make the bridge simpler.

Some functionality is still pending implementation, including the
actual wiring to use the bridge instead of SessionsSyncManager.

Previously, HostNameHandler::OnDeviceHostnamePropertyChanged() could
synchronously wait for machine statistics to be loaded by a
TaskPriority::BACKGROUND task while being called on the main thread:

chromeos::system::StatisticsProviderImpl::WaitForStatisticsLoaded()
chromeos::system::StatisticsProviderImpl::GetMachineStatistic()
chromeos::system::StatisticsProvider::GetEnterpriseMachineID()
policy::HostnameHandler::OnDeviceHostnamePropertyChanged()
chromeos::NetworkStateHandler::NotifyDefaultNetworkChanged()
chromeos::internal::ShillPropertyHandler::GetIPConfigCallback()

This was problematic since a TaskPriority::BACKGROUND task can take
"an arbitrarily long time to complete", and the main thread is
supposed to be responsibe at all times.

This CL fixes the issue by continuing the work asynchronously when
machine statistics are loaded rather than waiting synchronously.
