Previes detects reloads by looking at the cache load flags.
Unfortunately, an aspect of overriding the swipe to refresh behavior for
all offline pages is that those cache flags are not present. We can
checks specifically to make sure this is not a reload from an offline

Previously, preloaded Resources are not evicted from MemoryCache
in some cases, even when it is errored, in order to prevent
duplicated requests to an errored URL (once as a preloading request and
once as a non-preloading request). But now this exception is not
needed because Issue 652228 made preload matching done outside
MemoryCache.

This CL removes that exception and makes errored Resources always
evicted from MemoryCache.

//services/device/generic_sensors already has all the sensors that can
be used to implement the DeviceOrientation event:
https://w3c.github.io/deviceorientation/spec-source-orientation.html

Currently, //content/renderer/device_sensors uses sensors from
//device/sensors as its backend, and this is one of the CLs that
refactor
//content/renderer/device_sensors to use sensors from
//services/device/generic_sensor as the backend.

This CL refactors DeviceOrientationEvent to use sensors from
//services/device/generic_sensor. This CL factors out common
functionality between the DeviceMotionEventPump and
DeviceOrientationEventPump into DeviceSensorEventPump which they now
share as the common base class.

Standalone executable tool that helps developers view IAccessible2 object trees from any application.
This tool is an alternative to AccProbe, which is buggy, and AViewer, which is not feature rich.
The first version of ax_dump_tree is barebones and simply displays events on console, but has
a lot of room for future expansion (e.g., serve info to a GUI, dump the tree structure etc.).
The tool is similar is use to ax_dump_events.

As an example of how this makes easier, when there is a bug with NVDA/JAWS in Chrome that doesn't 
occur with Firefox, we can look at the object tree emitted by Firefox for the same content.

The ax_dump_tree tool shares code and formatting with the DumpAccessibilityTree browsertests. 

Use as follows:
ax_dump_tree --pid=[processid]
ax_dump_tree --window=[hwnd]   (start with 0x to use hex value)

- Read the value of "x-cdm-persistent-license-support" from the CDM
  manifest.json file.
- Push this info into WebPluginMimeType additional_param_names and
  additional_param_values when registering the CDM.
- In the renderer process, when registering Widvine key system, read the
  info from additional_param_names and additional_param_values.
- On Linux/ChromeOS, this info is not read from the manifest.json file.
  Rather, it's hard-coded in chrome_content_client.cc. We should
  update this in a future CL once we check in CDMs that supports
  persistent-license. Ultimately we will support component CDM on Linux
  and ChromeOS the CDM registration code will be removed from
  chrome_content_client.cc altogether.

In future CLs, we will implement key system support using CdmRegistry
instead of using WebPluginMimeType. Then we can abandon all the code
related to WebPluginMimeType additional_param_names and
additional_param_values.

crrev.com/c/704398 unified the availability of partner customizations
like bookmarks, homepage, etc. The rule was: they are available if
Chrome is a system package, or is force-enabled by a command line
argument "--allow-partner-customization".

Hiding behind a command line argument reduced the benefit of staged
deployment, and lowered the real world coverage.

Now the rule is: partner customizations are available if Chrome is a
system package, or is on pre-stable channels.
