@hlwarriner could you please help review this ? I think we may need some bracketing of #ifdef STARBOARD 16 in the old headers, on an off chance someone somewhere included them.

Sure. Yeah I think this needs SB_API_VERSION guards, similar to how they were used in https://github.com/youtube/cobalt/pull/1930.

I have added SB_API_VERSION guards.

@kaidokert, should someone with domain knowledge about the accessibility API take a quick look, too? I only focused on the mechanics of changing the Starboard API to an extension.

@johnxwork, can you have a quick look ?

Further - Android code still references starboard/accessibility.h and accessibility_internal.h here - this client code needs to be converted too, otherwise we can't land this change.

Internal CL 285260 at go/cobalt-cl/285260

[iuriionishchenko]

I've added the Android conversion. Tests are still to be followed up on, but otherwise ready.

Internal CL needs to be merged together with this

I am working on unit test and have some issue with debugging them. When I fix it I will update this PR to add the unit tests. Also I have a question. There is a comment, as I remember, in the CL to rename StarboardExtensionAccessibilityApi to CobaltExtensionAccessibilityApi but we steel have StarboardExtensionAccessibilityApi here and CobaltExtensionAccessibilityApi in the CL. I missed these changes I suppose when I was resolving conflicts. Which name should I used? I will update in the next commit.

Lets add those in a separate PR as a follow-up please. We are getting a bit time critical to get the Starboard header changes in, so i'm okay to do those later.

The naming should generally be "Starboard Extension" everywhere. Again this is okay to follow-up with cleanup CLs.

Most important here is that i can merge this with green builds together with internal CLs 285260 and 285223
