Frida logging helper

For adding temporary logging to help understand behavior. For when it is impractical to use Frida to instrument Frida.

Choose one of these and copy-paste it into e.g. lib/interfaces/session.vala, then use log_event ("name='%s'", name); to log.

When something appears to be hanging, try applying: x-async-debug.patch.
