f751f5e25e Store the remaining context properties with the listener properties 2016-05-13 20:21:20 -07:00
Chris Robinson
186b54aa3d Use a lockless method for updating listener and context properties 
This uses a separate container to provide the relevant properties to the
internal update method, using atomic pointer swaps. A free-list is used to
avoid having too many individual containers.

This allows the mixer to update the internal listener properties without
requiring the lock to protect against async updates. It also allows concurrent
read access to the user-facing property values, even the multi-value ones (e.g.
the vectors).

fcf9034c2b Calculate the listener matrix when a new orientation is specified 
This is so the matrix isn't derived each time a source is updated, and it will
make supporting user-defined matrices easier.

7d73ac4405 Avoid calling some AL functions from under the context lock 
There are still some more occurances to clear out (deletion in gen error,
effects, some filters), which shall be coming up. There is a possibility for a
deadlock between the listlock and the global/context lock, if another attempt
to get the listlock is made while under the context lock.
