Backport r29081: Fix player becoming unresponsive on Stop / Pause in some cases.

Browse source 
Fix for FS#11865: In tagtree_buffer_event, do not wait for database to
come online as that may never happen.  Rather, wait until it either
has come online or has decided that this will never happen.  Added a
new function to tagcache.c to export this information.
