ESLint rules have been added to enforce our JSDoc conventions. These
rules were introduced by updating `@metamask/eslint-config` to v9.
Some of the rules have been disabled because the effort to fix all lint
errors was too high. It might be easiest to enable these rules one
directory at a time, or one rule at a time.
Most of the changes in this PR were a result of running
`yarn lint:fix`. There were a handful of manual changes that seemed
obvious and simple to make. Anything beyond that and the rule was left
disabled.
The `tabId` of the message sender is now added to the middleware
request object. This step is omitted if the `tabId` is not provided.
This is done early in the middleware stack, so the `tabId` should be
available for any subsequent middleware to use.
The Onboarding Middleware has also been modified to get the `tabId`
from the request object, rather than expecting it as a parameter upon
creation.
This refactor will enable further uses of the `tabId`.
* Remove unused onboarding stream
* Pass `sender` through to `setupProviderEngine`
The Port `sender` has been passed down a few more layers. This allows
us to get more information from the sender deeper in the stack, but
also simplifies things a bit as well. For example, now the "fake"
URL object with the `metamask` hostname is no longer needed.
* Create onboarding middleware
This middleware intercepts `wallet_registerOnboarding` RPC messages. It
will register the sender as an oboarding initiator if possible, and
otherwise ignores the message.
