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.
this is done by this script:
ack -c "World.h" | ack :1 | sed 's/:1//' | xargs grep -c sWorld | grep :0 | sed 's/:0//' | xargs sed -i '/#include "World.h"/d'
i didn't checked every change but gcc haven't complained
