CHECK_PACKET_SIZE was pretty error prone; once it was forgotten mangosd could crash due to the asserts in ByteBuffer.h. That was exploitable by malicious players. Furthermore, there were duplicate checks: Additionally to CHECK_PACKET_SIZE, the ByteBuffer assertions keept an eye on not exceeding the packet boundaries - just to crash the server for sure in such a case. To prevent memory leaks or other undesirable states, please read in every handler all variables _before_ doing any concrete handling.
