DB/Guild: Fix incorrect input length limits

There is one incorrect field length related to guilds in the database, which can be used to cause an overflow client-side, by sending CMSG_GUILD_INFO_TEXT with long strings.

The guild information has the same 500 characters client-side limit as the guild bank tab information, but on server-side it can be 65k characters long. A lengthy guild info makes the whole Guild panel unusable.

Length of the other fields match the client's limits in the database: guild bank tab name (16), public note (31), officer note (31), motd (128), guild bank tab info (500).

Closes #11395

Scripting/Utgarde Pinnaccle: Fix visual during Svala's transformation
Merge pull request #11310 from Ric101/can_quest_reward

Core/Players: On CanRewardQuest, use the same item dest vector for all potential rewards

Solves issues where the player has enough bag space for each item individually, but not all of them together.

Example to reproduce previous issue:

Obtain Battle of the Crimson Watch (10781)
Make sure you only have 1 slot available in your inventory
Turn in the quest, watch as you don't receive one of the rewards
Core/Movement: Add LOS check for fleeingmovement target point.

Prevents fleeing or feared units from going to upper floor ignoring walls/ceilings with mmaps on(and usually get stucked).

Current implementation just randomly selects a distance and angle against the frighting unit, when in narrow circumstance such as underground caves, such targeting point would be at another floor.

Merge pull request #11377 from Yelvann/master

Core/Instances: Fix exploit too much players in instances/raids
Core/Player: Fix compile error introduced in ##11377 merge
Core/Entities: Fix combat state setting when FFA PvP flag is set

Description:
Currently there is an issue, when you are in FFA areas, but you dont have PvP flag activated.

You should get the PvP-In-Combat delay timer, but instead you just get the usual timer as if you would not fight in PvP.

Reproduction:
1) Get two players in FFA area Gurubashi arena down in the battle area (.tele Gurubashi)

2) Fight each other

3) When stopping combat, the combat state will switch off immediately. But it is supposed to switch off after some delay, because it was a PvP fight.

Closes #11103
