It was moved from electron-browser to electron-sandbox.

Not sure if it's used because it can return undefined, but it's
there now!

It looks like before, the ISetTerminalLAyoutInfoArgs and
IGetTerminalLayoutInfoArgs were part of the terminal interface, but now they're
just interfaces so this commit fixes the imports to get them from
vs/platform/terminal/common/terminalProcess.

It looks like they moved a bunch of terminal-related files around.

This only fixes the imports.

They removed mkdirp in favor of fs.promises.

Updated in marketplace.ts

This required a bit more work.

We moved a few things around and made use of multiplexLogService.

In the squash/merge update, we forgot to update the return type.

Add Promise<void> instead of void for shutdown method.

Looks like a few import updates and one minor update for language packs.

We had made this change ourselves, but now it's officially in the vscode
codebase. Super cool.

I'm not sure if we even use this but they changed the LocalizationService.o

It looks like it using one called ISharedProcessService now.

Looks like a minor update to the localization for the detailString
which I believe shows up when you go to Help:About.

This change refactors a lot of the get methods in the storageService.

I think it simplies a lot. It removes a bunch of methods.

Looks like they changed the doStore method to doInitialize in the
AbstractStorageService class.

It no longer accepts any parameters.

Inside the class BrowserStorageService, it looks like they replaced doStore with
getStorage.

However, at the time of writing this message, I am getting a TypeScript error
saying:
> Non-abstract class 'BrowserStorageService' does not implement inherited
> abstract member 'doStore' from class 'AbstractStorageService'.

Hopefully that will be disappear after I fix other errors.

It looks like a couple functions were added here
such as a readFile and writeFile.

No new dependencies were added in the 1.54.2 update.

With this the extension host is working again.

They now are all prepended with VSCODE_. Also added the parent pid to
ensure it shuts down when the parent dies.

It doesn't mean much until we persist terminals though, I think.

This makes it accessible via keyboard.

The theme callback would set innerHTML on the header which wipes out the
dismiss button. With an inner div we can replace the inner HTML without
worrying about other elements in the header.

Closes #2799.

Closes #2742.
