Spline movement controls movements of server-side controlled units (monster movement, taxi movement, etc).
Proper implementation of effects such as charge, jump, cyclic movement will rely on it.
However, need improve our states system before.
Technical changes:
* Added linear, catmullrom and bezier3 splines which based on client's algorthims. They can be reused for proper transport position interpolation.
* Precission increased. There are no more position desync issues since client's position calculation formulas used.
* Now possible to move by paths with multiple points, send whole path to client.

Original port for Trinity (ref #4629) Chaplain and Venugh
With the following incremental fixes during my review:
- Restore flightmaster end grid pre-loading
- Fix uninitialized Creature::m_path_id
- Add missing trinity_string entries for .movegens command
- Fix a bug in WaypointMovementGenerator that would trigger unexpected pausing at waypoints for various amounts of time
Known issues:
- Errors like WaypointMovementGenerator::LoadPath creature XXX (Entry: YYYYY GUID: ZZZZZZ) doesn't have waypoint path id: 0.
This is caused by bad DB data. This commit didn't "break" it.
Do not forget to re-run CMake before compiling.
- Re-write Svala Sorrowgrave
- Scripted achievement The Incredible Hulk.
This script was writen basing on work and data:
- Original TC script.
- Albis fix for Arthas sounds and texts https://github.com/TrinityCore/TrinityCore/issues/4002 .
- Ric event start fix.
- Recorded encounters uploaded on YouTube.
- Data found on ScriptDev2 forums.
- Iov's custom SD2 repo and Svalas's script https://github.com/Iov/scriptdev2 .
Also thx to:
- ZxBiohazardZx for pointing how to fix looting problem when boss is killed when flying.
- Aokromes for confirmig how many times event "Ritual of the Sword" is performed.
- Mini event with Arthas.
- Call Flames: timers of cast and time between "Ball of Flame" (48246) can be wrong (based on videos).
- Ritual of the Sword works and is performed once at 50% hp but:
a) Still need retail data for teleport position of Svala floating above player.
b) Need fully fixed spell Ritual of the Sword (48276), the triggering of spell Ritual Strike - Trigger Missile (48331) part was hardcoded.
- Spell Paralyze (48278) used by Ritual Channeler: fixed stacking and selection to ritual player only.
- Achievement "The Incredible Hulk": works but often Scourge Hulk don't get initial dmg from spell Ritual Strike (spell 48277 Effect #1 Value: 6650 to 7350).
- Looting problems when Svala was killed in air (require vmaps and option "vmap.enableHeight = 1" enabled in "worldserver.conf").
- Moved script_texts to creature_text.
It require option "vmap.enableHeight = 1" to work properly.
- The players AP should stack with combo points, not deadly poison stack.
+ some cleanup
Thanks @Cepox (and some others at google code issue tracker)
