Title:
  Implement a new API for overriding the user agent string

Status in Oxide:
  Fix Released
Status in webbrowser-app package in Ubuntu:
  Fix Released

Bug description:
  Currently the browser provides user agent string overrides using
  WebContextDelegateWorker (intercepting onGetUserAgentOverride for
  accesses to navigator.userAgent and onBeforeSendHeaders for modifying
  the User-Agent header). However, it's only possible to access these
  and resolve the user agent string on the IO thread.

  There is a requirement for being able to resolve the URL-specific user
  agent string when not on the IO thread (eg, mediahub), and this is not
  possible with the current design. As the browser's overrides appear to
  be a list of simple patterns (using "*" and "?"), there's no reason
  why we couldn't expose a new API (WebContext.userAgentOverrides) to
  allow the browser to specify the set of overrides. We would then do
  the matching inside of Oxide on whatever thread requires it using an
  API that is thread-safe internally, rather than calling in to an
  application provided script to do the pattern matching and determine
  the override.

  This would mean that WebContext.userAgentOverrideDelegate would be
  deprecated (WebContext.networkRequestDelegate wouldn't be, as it has
  other uses besides setting the User-Agent header in HTTP requests).
