Bug 1576624 introduced the ResourceWatcher API, accessible via toolbox.resourceWatcher. This API will help listen to data that is being created early, when the document just started loading.

We should migrate the whole DevTools codebase to this API for any data that:

DevTools frontend listen to, or care about,
and,
may be created or be notified early, when the document just starts being loaded.
This data will typically be: console messages, errors, warnings, sources, Root element NodeFront, storage values, network events, stylesheets, ...

We are typically not going to use this API for:

data being fetched on-demand, from user's input. For ex: webconsole evaluation input, or, DOM element expands from the Markup view.
events which we only want to record when the user cares about them. For ex: animation events.

For some more high level context, please have a look at Migration to Fission-compatible APIs, which describes all Fission-related refactorings.

The typical task for this bug will be about migrating code that:

start listening and register a RDP event listener,
retrieve already existings data,
from panel's codebase, to the ResourceWatcher module, in the LegacyListener object.
And then, the panel should use the ResourceWatcher instead.

Bug 1620234 is a good example of such migration, applied to Console Messages.
Bug 1623699 is also useful example as it demonstrates how to write tests for such migration.

This bug is about focusing on only one usecase in the console: the JS Errors.

JS Errors are currently being listened via WebConsoleFront.startListeners(["PageError"]), from here:

And already existing errors retrieved from here:

Attached file Bug 1625905 - Use the ResourceWatcher API to fetch JS Errors. r=ochameau. — Details

In this patch we add a new resource type for page errors.
We don't do anything specific for CSS Warnings yet, as they're going
to be handled as part of Bug 1625910.

A test is added (following devtools/shared/webconsole/test/chrome/test_page_errors.html
as an example).
A couple function that were used for the console-messages test
are moved into head.js as they're also used in the error-message test.

We take this as an opportunity to "block" resources based on the target
type and the value of the contenttoolbox.fission pref, directly in
the resourceWatcher _onResourceAvailable method.
Previously it was done in the legacy listeners, but since we'd
reimplement the exact same thing we had in console-messages into
error-messages, it sounded good to put it in a centralized area.
