dvd, bd: don't unnecessarily block on demuxer/stream all the time

Browse Source 
This was completely breaking any low-level caching. Change it so that at
least demuxer caching will work.

Do this by using the metadata cache mechanism to funnel through the menu
commands.

For some incomprehensible reason, I had to reorder the events (which
affects their delivery priority), or they would be ignored. Probably
some crap about the event state being cleared before it could be
delivered. I don't give a shit.

All this code sucks. It would probably be better to let discnav.c access
the menu event "queue" directly, and to synchronize access with a mutex,
instead of going through all the caching layers, making things
complicated and slow.
