[8389] Implement check really read received packet size and warning it not all data read.

Browse source 
* This let more easy catch packet structure chnages at client switch.
* Fixed structure CMSG_GUILD_BANK_SWAP_ITEMS
* Fixed structure CMSG_SPLIT_ITEM, CMSG_SELL_ITEM
* Added read data amount fixes for some other packets.

Thanks to TOM_RUS in help check correct packets structure.

Note: not all packets possible fixed. Please report for not fixed cases at errors:
"opcode %s (0x%.4X) have unprocessed tail data (read stop at %u from %u)"
