Merge commit 'a8a1bac7' of github.com:Fluorohydride/ygopro into server

This is very popular in custom card or rush duel communities. So we have to change it back.

* use memcpy in DuelClient, NetServer

* NetServer: discard too large packet

* DuelClient: discard too large packet

* replace memcpy with std::memcpy

* disconnect when the packet is too large

* check packet_len

* check len in HandleCTOSPacket()

* check len in HandleSTOCPacketLan()

* remove bool type in HostInfo

* check len in packet handling

* add boundary check to STOC_CHAT packet

* use memcpy in DuelMode::JoinGame

* add DECK_MAX_SIZE, DECK_MIN_SIZE

* fix DuelMode::UpdateDeck()

* fix
