bjorn 82a309a56d Draft new effects API; 
- A list or map of effects can be provided to newSource.
- false can be used to bypass effects.
- All effects are enabled by default.
  - Occlusion-y effects should only take effect when setGeometry is called
    - Spatializer is responsible for ensuring this.

bjorn c531243d7d phonon: Source:get/setFalloff; 
The falloff is the minimum distance at which inverse distance
attenuation takes place.

A non-positive value disables distance attenuation.

In the Lua API, nil can be used to disable attenuation, a boolean can be
used to enable attenuation with a default minimum distance, or a number
can be used for full control over the parameter.

mcc 9ba4037e74 LOVR_USE_OCULUS_AUDIO 
This is a large patch which adds a new Oculus Audio spatializer. Oculus Audio is slightly different from the dummy spatializer in a few ways:

    - It *must* receive fixed-size input buffers, every time, always.
    - It can only handle a fixed number of spatialized sound sources at a time.
    - It has a concept of "tails"; the spatialization of a sound can continue after the sound itself ends (eg echo).

Changes to audio.c were needed to support Oculus Audio's quirks:

    - audio.c now supports a "fixedBuffer" mode which invokes the generator/spatializer in fixed size chunks
    - Each source now has an intptr_t "memo" field that the spatializer may use to store whatever (Oculus spatializer uses this to handle the sound source limit).
    - The spatializer interface got a couple new methods: A "tail" method which returns a sound buffer after all sources are processed; and "create" and "destroy" methods that are called when a sound source is created or destroyed (Oculus spatializer uses this to populate/clear the "memo" field).

Along the way some other miscellaneous changes got made:

    - lovr.audio.getSpatializerName() returns the current spatializer
    - Spatializer init now takes in "config in" and "config out" structs (Spatializer changes fields in config out to request things, currently fixed buffer mode).
    - lovr.conf now takes t.audio.spatializer (string name of desired spatializer) and t.audio.spatializerMaxSourcesHint (Spatializers with max sources limits like Oculus will use this as the limit).
    - audio.c went back to tracking position/orientation as vectors rather than a matrix
    - A file oculus_spatializer_math_shim.h was added containing a minimal copypaste of OVR_CAPI.h from Oculus SDK to support a ovrPoseStatef the spatializer API needs. This may have license consequences but we are probably OK via a combination of fair use and the fact that a user cannot use this header file without accepting Oculus's license through other means.

Some work remains to be done, in particular there is an entire reverb feature I did not touch and LOVR_USE_OCULUS_AUDIO cannot be activated from tup. Oculus Spatializer works better when it has velocity and time information but this patch does not supply it.

If there was ever some sort of hypothetical switch to a different
audio library, this would make such a switch easier.

bjorn 69dd0d4674 audio: rm paused and stopped states; rm rewind; 
- There is now just one "playing" state.
- Instead of rewind, use :seek(0).

Note that now there is no way to resume or rewind all tracked sources.
This can be improved in the future if there's a need for it, probably
using variadic or table-based variants of the audio module functions.
