So changing this was a little backwards. The goal here is to allow using
libsysprof-2 without polkit, it just won't have the ability to elevate
privileges.
Without this, after logging in you are already multiple seconds into your
profiling session recording. Not ideal. So instead, we do the async polkit
auth upfront during SpSource::prepare(), and then toggle ready after we
have received notification.
This is a major redesign a modernization of Sysprof. The core data
structures and design are largely the same, but it has been ported to
Gtk3 and has lots of additions that should make your profiling experience
smoother. Especially for those that are new to profiling.
There are some very simple help docs added, but we really need the
experts to come in and write some documentation here.
