10a9753183 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.

031a2a1b1e 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.

b65bc45236 Add a corrective, click-remval sample value offset 
This will hopefully be more effective and rebust at removing clicks and pops,
particularly from starts and stops in the middle of a sound. Based on an idea
by Ben Davis.
