- Improve snapshot rate and data rate control

- Make server send packet fragments and queued packets when server is idle
- Voip protocol detection is tied to com_protocol making past-end-of-message reading unncessary
- Use Hunk_AllocateTempMemory() for buffering VOIP packets and fix buffering scheme that ryan hates so much
- Disable packet scrambling for new protocol as it is useless now
- Get rid of the old packet scrambling functions predating latest point release
- Use Hunk_AllocateTempMemory() for netchan packet queue to fix memory leak when client gets disconnected with packets in the queue
- Use Hunk_AllocateTempMemory() for download blocks to fix memory leak when client gets disconnected with download blocks in the queue
- Fix SV_RateMsec to account for udp/udp6 packet lengths
