/*
* IPC Transaction protocol for the WebAuthn DOM API. This IPC protocol allows
* the content process to call to the parent to access hardware for
* authentication registration and challenges. All transactions start in the
* child process, and the parent replies with a "Confirm*" message, or a
* "Cancel" message if there was an error (no hardware available, no registered
* keys, etc) or interruption (another transaction was started in another
* content process). Similarly, the content process can also request a cancel,
* either triggered explicitly by the user/script or due to UI events like
* selecting a different tab.
