Previously, two players entering the same cell only sent and received their latest changes for dynamic stats, attributes, skills and equipment when they started sharing that cell.
Previously, whenever a single attribute value changed for a player, that player then sent a PlayerAttribute packet with all values for all 8 attributes.
This did not cause anywhere as much packet spam as PlayerSkill used to, but there was no good reason not to fix it as well.

Previously, whenever a single skill value changed for a player, that player then sent a PlayerSkill packet with all values for all 27 skills, plus the player's progress towards the next level and the bonuses to each attribute on the next level up as the result of sklll increases thus far.
This commit makes PlayerSkill contain only the values of specific skills, moves the player's progress towards the next level to PlayerLevel packets, and moves the bonuses to each attribute on the next level up to PlayerAttribute packets.
Players now also send a PlayerSkill packet whenever their progress towards a new point in a skill changes. This was previously avoided so as to not have massive packet spam.

Previously, charGenStage.end was doing double duty as both the variable indicating the number of CharGen stages and – when set to 0 – the variable indicating that CharGen was over. The latter role is now filled by a new boolean.

A main priority in TES3MP development is to avoid making major changes to OpenMW code, so as to avoid merge conflicts in the future. Whenever avoiding potential conflicts seems especially difficult for the proper implementation of a particular multiplayer feature, that multiplayer feature is often put off until later or partially implemented with the intent of being revisited in the future.
Container sync is the perfect example. Previously, the OpenMW code for container actions was kept exactly as it was, with clients unilaterally accepting their own container changes as per singleplayer-specific code, with only the addition that clients sent container packets every time they made a change in a container, packets which were then forwarded unquestioningly by the server to other players. This meant that two players clicking on the same item in a container at the same time both managed to take it, thus duplicating the item.
Immediately after the packets were already forwarded, server scripts were able to check for incorrect changes, such as the removal of more items than should have existed in a container, but they had to send their own packets that attempted to fix what had already been accepted on the initial client and then forwarded to all clients, which was quite onerous in some scenarios, such as when a player on a slow connection immediately dropped items in the world after taking them from a container (which is why the default TES3MP serverside scripts made no attempt at sending corrective packets at all, preferring to expect the matter to be solved in a later C++ implementation).
This commit fixes item duping in containers by preventing container actions from initially running on clients and by ending the automatic forwarding of container packets by the server. Instead, clients now send container packets that act as requests for container actions, and serverside scripts have to forward these requests themselves. In other words, without a matching Container event in the server's Lua scripts, players are completely unable to affect containers for themselves or for others.
To forward a received Container packet, the following line must be used in a Container event in the Lua scripts:
tes3mp.SendContainer(true, true)
When an invalid action count is used in a container request, the serverside scripts can amend it using the following new function:
tes3mp.SetReceivedContainerItemActionCount(objectIndex, itemIndex, actionCount)
Thus, the serverside scripts are able to allow only container actions that are correct based on their own recorded contents for that container.
The OpenMW code allowing unilateral container actions in mwgui/container.cpp is now prevented from executing. When a player's container request is returned to them, code in mwmp/WorldEvent.cpp simulates those container actions instead.
Certain servers do not want the players to have debug information about the locations and actions of other players, so a client's log level can now be enforced by the server via the GameSettings packet.

This allows the OnPCDrop variable to get set correctly even when object placements have to go through the server first in order to gain a unique multiplayer index (mpNum).
Among other things, this makes it possible to roll marijuana joints in the popular mod "Tribunal Code Patch".
