8d0f212521 When dropping bots, don't move to CS_ZOMBIE. Go straight to CS_FREE. 
They aren't a real network connection, so you don't want to waste time before
 opening the slot for humans.

  Fixes Bugzilla #4243.

8ab3f7af8d Changed the protocol for VoIP packets to support legacy clients. 
Previously, a legacy client wouldn't get a VoIP packet, but if they did,
 they'd panic and disconnect. Now they ignore them and continue on. This also
 gives us the framework to add other features legacy clients can ignore.

Oh, this also has the benefit of allowing us to store incoming VoIP for
 playback in recorded demos. They'll play the chatter on VoIP clients, and
 be ignored on legacy ones. Huge win.

da75e9fda8 * (bug 3027) don't trust the "ip" value in the userinfo string since a client 
could set this.  disconnect (or disallow connection for) a client that
  has a userinfo string that's too full for "ip" to be added properly.

189e8b33f3 * (bug 2784) help to prevent reliable command overflow in cases when a slow 
client is loading the map on a busy server. Specifically, hold back all
  configstring update commands while the client is CS_PRIMED.  Once the
  client goes from CS_PRIMED to CS_ACTIVE, send the cleint commands for
  updating each of the configstring indexes which were updated while the 
  client was CS_PRIMED.
