62036745f3 Separate config init from library init 
OSX has a bug where the file descriptor resource limit can't be increased once
certain functions (such as fopen) are used. Since lib initialization happens in
a global constructor and includes opening and parsing config files, it prevents
apps from being able to increase the rlimit once the lib is loaded, which is
usually before main().

By delaying config init, it allows apps the opportunity to change the rlimit
before calling certain OpenAL functions.

db3cb23c1d Add an option to reverse Z panning of mono sources 
Applications that are not built around OpenAL's orientation system need to
convert their given vectors to it. Depending on how this is done, it can lead
to proper stereo (left-right) panning with improper surround sound (front-back)
panning, which thusly sounds correct with stereo output and incorrect with 4+
channel output.

This option is intended to help fix playback of such applications on surround
sound systems, without having to resort to forcing stereo output.

56d9418119 Add an HRTF filter for mono sources 
The data is based on the KEMAR HRTF data provided by MIT, which can be found at
<http://sound.media.mit.edu/resources/KEMAR.html>. The compact measurements
were used. See hrtf_tables.inc for more information.

The filter is only available for stereo output, using a 44100hz playback rate.
Note also that it currently only applies to mono sounds, and the cf_level and
head_dampen config options are ignored while it is active.

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.

678d0b87d0 Apply the device matrix to the multi-channel source matrix

device channels. Multiplying the device matrix with the source matrix results
in a matrix that has the same effect as applying the source matrix followed by
the device matrix, so all the channel remixing can be done in one place.

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.
