Low effect limits about openal-soft HOT 2 CLOSED

Since commit d3cc867, the default auxiliary effect slot count has been raised to 64 and the maximum number of source sends is raised to 16.

Note that for the effect slots, having an effect slot generated can incur some processing cost even if nothing is feeding it, so it's best to only allocate what you need to use. The cost can be minimized by setting a null effect type on unused slots, though not having it at all when it's not used is even cheaper.

For source sends, the default you get is 2. You can use ALC_MAX_AUXILIARY_SENDS with context creation or device reset attributes to request more, up to 16 (you can try to request even more, but it'll be clamped; query ALC_MAX_AUXILIARY_SENDS using alcGetIntegerv afterward to see what you got). Having more sends does slightly increase CPU cost since it's more properties that need to be processed for each active source, but it shouldn't be too bad.

Let me know if using the higher counts causes a problem. There's not too much that stresses a high number of effects and sends, so some feedback would be appreciated.

Closing since the number of effect slots has been significantly increased, and the number of source sends has increased as well. Even on modern systems, I don't expect this could be increased much further without performance problems, though there's always room for more general improvements.
