Remove Env from caller, and don't store Env in isolate. We don't need it, we
can execute all runtime code from the Executor (which we store a pointer to
in the v8.Context)
Add Node writer. Different CDP messages want different child depths. For now,
only support immediate children, but the new writer should make it easy to
support variable.
This expands on the existing CDP node work used in DOM.search. It introduces
a node registry to track all nodes returned to the client and give lookups to
get a node from a Id or a *parser.node.
Eventually, the goal is to have the Registry emit the DOM.setChildNodes event
whenever necessary, as well as support many of the missing DOM actions.
Added tests to existing search handlers. Reworked search a little bit to avoid
some unnecessary allocations and to hook it into the registry.
The generated Node is currently incomplete. The parentId is missing, the
children are missing. Also, we still need to associate the v8 ObjectId to the
node.
Finally, I moved all action handlers into a nested "domain" folder.
When set, this disables the host verification of all HTTP requests. Available
for both the fetch and serve mode.
Also introduced an App.Config, for future command line options which need to
be passed more deeply into the code.
