* Enable clients to move turrets
This allows clients to user server data to move turrets according to the timing and target data on the server. Uses a small packet to do so.
* Object Update Refactor
1. Keeps the object update packet aligned, even if the ship is dying or has not yet arrived on the client.
2. Properly handles model point shields (yes, that's what was causing multi to crash the most!)
3. Reworks positional interpolation timing and adds rotational interpolation, by sending timing information with every object update packet in a header shared between objects.
4. Saves a lot of bandwidth by only sending data that is changing. (no more sending all subsystems once per second!)
5. Better handles out of order packets (but can still use their information if recent enough!)
6. Builds the basis for Rollback by beginning to record the positions and orientations and velocities of ships for the last 30 frames.
7. Adds subsystem rotation -- Yeah, you saw that right, subsystems will now spin in multi.
8. Waypoint movement is now enabled via sexp, and time to arrival of waypoints is updated on the target info gauge.
* Fix edge case crash and Incorporate feedback
* Clean Up Interpolate Angles Quick
* Restrain the client
* How was this still here???
* Make sure every part of OO uses OOC_INDEX_NULLPTR_SUBSYSTEM define
* Fix Way to Store Return Values
* Ok travis, we get it
* Ok travis.........
Removes about half of the Int3()'s in multiutil.cpp by making Assertions more robust, changing two functions to void type (because there was no way to get an error value from them, anyway), and adding two Verify()'s in case we ever decide to start using the multi variable change functions.
Squash History:
1) Forgot to change one Assert to Assertion
2) Change Verify to Assertion, because of better argument support.
3) Fix a couple copy paste errors
Just a quick PR to make multiutil slightly more readable by removing one unused function (whose functionality is already in the object update packet), two globals which we only increment and we do nothing with, and some defines that have been commented out because the size returned can actually vary.
Remove support for the IPX protocol. The IPX selector button in the multi
options menu is now hidden, and the TCP button is disabled since there is no other option.
