Follow-up to #5040. This extends the checks to most iterations over `obj_used_list` in FSO. There are a few exceptions such as `waypoint_add` and `waypoint_remove`, plus a few others. And none of the object iterations in FRED have the guard because FRED does not use the same object life cycle as FSO.
Adds gravity! Applies on a per-mission basis, and weapons, ships, debris, and asteroids now have a configurable "gravity const" which multiplies the effect of gravity on them, by default everything except debris is 0 (meaning no effect even when the mission has gravity). AI and the lead indicator will also lead for ballistic trajectories as well, given a gravity-affected weapon. No FRED support or gravity direction control yet, to come in later PRs.
* Fix subsystem change handling code
Make sure that subsystem help actually gets updated.
* change from pointer to literal
I had decided to use `new` in the past when I was less experienced. So this changes it back to regular angle variables.
(And White space fix requested by Wookie)
The ship record for player ships is not always accurate. So as to correct entries as valid packets are received.
Also, remove a case where null vectors were being passed to the physics engine.

Scripts that render models in the On Object Render hook were effectively doing immediate renders in the middle of queued renders. This caused some data, such as model orientation, to 'leak' between renders. It might also have something to do with why the bug in #4637 had the particular graphical side effects that it did.
Anyway, changing the immediate renders to queued renders fixes the leaky orientations, and is probably a good upgrade for other reasons as well.
Change Interpolation function to bool
And calculate last position instead of just setting it
This should help FSO prevent some very odd collision issues when two ships collide
`Ai_flag_names[]`, `Object_flag_names[]`, and `Ship_flag_names[]` all had an associated `#define` containing their length that had to manually be incremented whenever new flag names were added to the list. This commit instead makes the number of flags in the list be computed by simple `sizeof` division, so now adding a new entry just requires adding the entry, rather than remembering to bump a `#define`. Tested in FRED to make sure populating `OPF_SHIP_FLAG` entries still works.
Removed useless light_ignore_objnum and affected_objnum lighting data, light_add_point_unique() subsequently removed as well, and cleaned up unused parameters.
It's theoretically possible for `parent_type` to get out of sync with the parent's type, particularly if the parent is destroyed. Since the field is almost never used, it can be removed.
Should fix#4105.
Mostly renaming of fields and functions, and moving some modelread sections into functions. This reorganization will put the code on a better footing for the model translation feature. No model translation code is included yet, and there should be no change in functionality.
* Switch Multimsg to use netsig for animations
* Unique-ify animation ID's
* Clang Tidy
* Implement first suggestions
* Implement suggestions 2
* Add get model instance safeguard
The Rotators_locked flag was created specifically as a lab option that didn't affect animations or intrinsic rotations, so return it to that scope. Also rename it to clarify that it applies to subsystems and to be future-proof for submodel translation.
This moves submodel rotation out of the AI pipeline and into object movement. With the exception of turret rotation (which remains in the AI code) this now allows all types of submodel rotation to happen in the same place. Many associated functions have also been cleaned up.
In addition to making the code cleaner and clearer, this will make it much easier for intrinsic rotations and new animations to be applied to non-ship objects, such as weapons.
* Prevent Crashes from Weapons being deleted during the collision process
This puts in some safety checks to keep FSO from crashing while doing collision detection when close to the object limit.
* Remove Problematic Assertions and INT3's
Keeps FSO from crashing when low on Object slots from failed weapon and beam creations.
* Simplify Code with a good suggestion

This flag is vestigal. It was likely used in the FS1 codebase and then was not removed by the rushed FS2 multi team. Whether or not an object uses physics_sim is determined earlier in `multi_oo_is_interp_object()`
* Multiplayer Dumbfire Rollback
This creates a packet that sends the relative position and orientation info for a primary or dumbfire missle shot. The client creates this packet when firing those two types of weapons and sends it to the server. The server goes back to the frame that the client fired the weapon and quicky resimulates all the frames in-between.
This includes collision detection, restoring positions, orientations and veloicties, but not subsystem orientations.
* Address Feedback
* allow clients to send subsystem info
* Check for object number not weapon number
* Readability Adjustment
