- Apply parts of Ben Millwood's target bitfield patch (#3787)

Browse source 
- Fix Ryan's FIXME and have voip packet buffer on the server dynamically allocated via Z_Malloc and store pointers in a circular buffer
- Improve voip target parsing on top of Ben Millwood's patch
- Add new "spatial" target where speaker is spatialized in 3d space and can be heard by all clients in hearing range (s_alMaxDistance)
  (#4467)
- Decrease voip sound lengths from 240ms to 80ms per voip packet to mitigate udp packet loss and decrease latency
- Protocol version incremented to 71
