These commands are used for the "Edit As HTML" feature in DevTools. This
renames our existing HTML getter IPC to indicate that it is for outer
HTML. DevTools will need a separate inner HTML getter.
Since cross-site navigation is a pretty frequent task, creating a spare
process is commonplace in other browsers to reduce the overhead of
directing the target site to a new process.
We store this process on the WebView application. If it is unavailable,
we queue a task to create it later.
This requires a couple of amendments to the DOM node serialization.
Namely, we need to include the HTML namespace, otherwise the context
menu item to create a new node is disabled.
This supports evaluating the script and replying with the result. We
currently serialize JS objects to a string, but we will need to support
dynamic interaction with the objects over IPC. This does not yet support
sending console messages to DevTools.
This adds a command line option to enable the DevTools server. Here, we
make the application the DevToolsDelegate to reply to requests from the
DevTools server about the state of the application.
This commit adds a "echo_server_port" property to `WebContentOptions`.
Additionally, it makes `Application::web_content_options()` return a
mutable reference instead of a const reference so that we can set the
port value from the fixture.
LibWebView now knows how to launch RequestServer and ImageDecoderServer
without help from the UI, so let's move ownership of these services over
to LibWebView for de-duplication.
