Get WebExtensions running

[RangerMauve]

Since we are no longer using Kiwi as a basis for the browser, but instead are using Bromite, we'll need to figure out how to get we extensions working again.

We can try to figure out how Kiwi does extensions by reading their source code changes and try to apply a subset of them ourselves.

This is important to enable us to reuse extensions between mobile and desktop

Found this repo which has some web extension stuff taken out of Kiwi: https://github.com/dvalter/chromium_extension_patches

Looks like the extension C++ code is wired up to the app menu here: https://github.com/dvalter/chromium_extension_patches/blob/master/0001-Kiwi-Introduce-extensions-support-R80.patch#L2683

Sme stuff in the background service factory got commented out? https://github.com/dvalter/chromium_extension_patches/blob/master/0001-Kiwi-Introduce-extensions-support-R80.patch#L3108

There's an Android-specific "background mode manager" implementation which no-ops some stuff that presumably only makes sense on Desktop. https://github.com/dvalter/chromium_extension_patches/blob/master/0001-Kiwi-Introduce-extensions-support-R80.patch#L3139

Looks like some static resources get added in? https://github.com/dvalter/chromium_extension_patches/blob/master/0001-Kiwi-Introduce-extensions-support-R80.patch#L3242

Some more DependsOn calls get removed here: https://github.com/dvalter/chromium_extension_patches/blob/master/0001-Kiwi-Introduce-extensions-support-R80.patch#L3590

There's some stuff that adds a permission prompt for RegisterProtocolHandler here: https://github.com/dvalter/chromium_extension_patches/blob/master/0001-Kiwi-Introduce-extensions-support-R80.patch#L3621

Some devtools build flags here: https://github.com/dvalter/chromium_extension_patches/blob/master/0001-Kiwi-Introduce-extensions-support-R80.patch#L3671
Might not be relevant to extensions though? Seems to just explicitly remove extension support.

Seems like plugins are getting removed here? https://github.com/dvalter/chromium_extension_patches/blob/master/0001-Kiwi-Introduce-extensions-support-R80.patch#L4093

Looks like some sort of no-op constructor was added for extensions::NetworkingPrivateDelegateFactory? No clue why. https://github.com/dvalter/chromium_extension_patches/blob/master/0001-Kiwi-Introduce-extensions-support-R80.patch#L4357

A bunch of PDF viewer related things are commented out: https://github.com/dvalter/chromium_extension_patches/blob/master/0001-Kiwi-Introduce-extensions-support-R80.patch#L4371

Some sort of Browser instance is getting set up here in the extensions windows APIs: https://github.com/dvalter/chromium_extension_patches/blob/master/0001-Kiwi-Introduce-extensions-support-R80.patch#L4445

Also does some funky stuff for getting the Browser instance from a widnow id: https://github.com/dvalter/chromium_extension_patches/blob/master/0001-Kiwi-Introduce-extensions-support-R80.patch#L4513

The window list gets generated from the tab list: https://github.com/dvalter/chromium_extension_patches/blob/master/0001-Kiwi-Introduce-extensions-support-R80.patch#L4538

A bunch of tab bar specific stuff gets commented out: https://github.com/dvalter/chromium_extension_patches/blob/master/0001-Kiwi-Introduce-extensions-support-R80.patch#L4550

New implementation for getting the tab list: https://github.com/dvalter/chromium_extension_patches/blob/master/0001-Kiwi-Introduce-extensions-support-R80.patch#L4616

New implementation for getting tabs in a window: https://github.com/dvalter/chromium_extension_patches/blob/master/0001-Kiwi-Introduce-extensions-support-R80.patch#L4681

There's a bunch of other API related things we should be aware of in there, I'll skip pointing them out.

No clue what the media router has to do with extensions, but something was added there. Might be related to chrome cast stuff?

The web_applications folder has some extensions related code which might be getting used, and some stuff got commented out: https://github.com/dvalter/chromium_extension_patches/blob/master/0001-Kiwi-Introduce-extensions-support-R80.patch#L14647

Seems to be related to native plugins we we don't need to think about.

In the extensions API dir processes.idl gets added to the schema_sources for Android. Not sure why there'd even be an is_android check in that file. 🤷 https://github.com/dvalter/chromium_extension_patches/blob/master/0001-Kiwi-Introduce-extensions-support-R80.patch#L14967

[RangerMauve]

It seems like a bunch of stuff got imported by accident due to how the build.gn flags got configured, and we can probably ignore most of it / add #if !defined(OS_ANDROID) checks.

[RangerMauve]

Looks like a bunch of stuff is related to signin being included on Android, maybe we can ignore a lot of it if we just need extensions.

[RangerMauve]

In particular the media router stuff seems to be taking up a huge amount of resources. Maybe we can omit it somehow and reduce the patch drastically. This may also be related to WideVine DRM stuff?

[RangerMauve]

Maybe we can omit some of this zoom level stuff too and just make the API a no-op on Android / skip all the imports.

[RangerMauve]

There's also a bunch of stuff related to payments in the patch which I think we can ignore.

[RangerMauve]

A bunch of stuff is related to Kiwi's Devtools support. We should probably make a separate issue to document it.

[RangerMauve]

Went through the entire patch, next I'll look at just the bits that I think are relevant.
