* This has been necessary due to the undefined call order of
of static objects. Fixes#12315.
* The bug has been caused by the linker which free unused resources,
making the BMediaRoster to run in a zombie state. In this state
anything such as a message could make the looper to crash.
* The class is reintroduced with some differences though, we are
going to protect it from another thread calling Roster() while the
BMediaRoster is quitting and implement BMediaRosterEx::Quit.
* Unregister registrar notifications before we quit our thread. Avoid
to uninitialize anything from QuitRequested as it may cause problems.
