Half-Life Linux Dedicated Server v3.1.1.1 to v3.1.1.1d Update

Changes/Additions:
------------------
- Added bot count to "details" server query reply.
- Flipped anti-DoS logic to check per user and then global rate limits.
Changed it so users exceeding personal rates don't add into the global rate
calculations.
- Performed optimizations on engine to improve performance.
- Linux: Added "-pidfile " argument to hlds to get it to write the
pid of the dedicated server process to the file specified.
- Linux: Improved "-debug" command to look for core. files.
- Linux: hlds echoes to the controlling tty rather than stdout (solves
redirecting output no longer showing key presses).
- HLTV: Changed "status" output, more info displayed.
- HLTV: Added cvar "maxloss", default 0.05, if packet loss exceeds this
threshold, new spectators are rejected.
- HLTV: Zero delay possible for direct broadcasts without game buffering
("delay 0").
