Add a compatibility option to treat cone angles as half angles
...
All previous versions of the library treated the source cone angles as half
angles, which is contrary to the spec. Setting the __ALSOFT_HALF_ANGLE_CONES
environment variable to "true" or "1" restores the buggy behavior for
compatibility with applications that expect it.
This is not a config file option because new apps should not be made to depend
on the old behavior.

Implement a basic non-real-time loopback device
...
Currently it behaves just like a normal device except contexts are only
processed during calls to alcRenderSamples. Additionally, the ALC_SYNC and
ALC_REFRESH context attributes are not valid for these devices, and there are
two new context attributes to specify the rendering format: ALC_FORMAT_TYPE
and ALC_FORMAT_CHANNELS. These each take one of the type and channel enums
added.
This stuff is subject to change.
