CL_WritePacket

Create and send the command packet to the server
Including both the reliable commands and the usercmds

A client packet will contain something like:

4 sequence number
2 qport
4 serverid
4 acknowledged sequence number
4 clc.serverCommandSequence
<optional reliable commands>
1 clc_move or clc_moveNoDelta
1 command count
<count * usercmds>
