wookieejedi 78d2e663d7 One fix and one enhancement to AI shield behavior (#6737)
* One fix and one enhancement to AI shield behavior

This PR adds one fix and one enhancement to AI shield behavior.

1) Fix: Testing, especially in FotG, revealed an edge-case bug with shield management where the AI will not direct shield energy to a quadrant if it was hit when that quadrant was down. In other words, if a shield quadrant is knocked down to 0 and continues to be shot the AI will not realize it needs to direct energy to that quadrant. This is because `quadrant` is set to -1 if a shield segment is down. This ensures that the resulting effects and damage calculations properly ignore that quadrant downstream, but it also results in `aip->last_hit_quadrant` being set to -1. This PR adds a fix to properly record which shield was actually hit, so that the AI knows to direct energy to that quadrant.

2) Enhancement: In combat situations with fire coming from many directions, it is good practice to keep shields equalized, so this PR adds a flag for the AI to always attempt to balance shields, even if it is being fired upon (instead of the current behavior to always direct energy to the hit shield quadrant).

Both flags are tested and work as expected.

* fix copy paste

* rename to avoid previous confusion

* also make as ai class flag

Goober5000 ad8dee0f2b addendum to fixed missile detonation
As discovered by PDFCommand and tracked down by Asteroth, there was another "missed target" check in `ship_weapon_check_collision()`, in addition to the more comprehensive check in `weapon_home()`.  Since the check is redundant and there is an existing `$Fixed Missile Detonation:`, skip the check if the flag is active.

Goober5000 44c949f8d5 optimize collision code a bit
This was motivated by the recent Coverity report.  Coverity noticed that a few of the copy assignments could be replaced by move assignments, but on further investigation one copy each in `ship_weapon_check_collision()` and `beam_collide_ship()` can be entirely removed, another either/or copy in each can be replaced with an either/or pointer assignment, and a few copies can be done only when needed.  Another vec3d copy (`hit_dir`) can be replaced with a vec3d pointer; it is no longer modified locally, so there is no longer a need to keep a local copy.

wookieejedi 3f21ba4d17 Expose decal options useful for modders (#4957)
* Fixes CTD with decals on dying ships

If a ship was getting shot with weapons that used decals, the decal code would hit an assertation, because the invalid decals were not being all removed.

This PR updates the decal cleanup loop, to ensure that no decals are missed and all invalid ones are removed. Tests confirm this fixes the issue.

Also cleaned up some comments and moved another assertation before setting of variables.

* Exposes modder useful options to decals

Now that decals are very stable, this PR exposes two options that are very useful for using decals, a random range for the radius along with the option to have a random rotation when the decal is created.

Tested and everything works as expected.

* add script ability to toggle decals

* properly use set arg not func

* fix two minor things in decal shader

Asteroth 219bcca23a Implement gravity (#4803)
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.

Goober5000 3a4794305f Convert some Lua hooks to the new style to add documentation
This takes a few of the existing hooks and converts them to the new style of hook definition which can include more extensive documentation and enumeration of supported hook variables.

This is an updated version of #3151 to work with the latest codebase.

NOTE: Before this can be integrated into the codebase, it needs an implementation for `bool script_state::IsActiveAction(int hookId)` which apparently only has support for old-style script hooks.

asarium ac77a6eb77 Fix render orientation for decals
The orientation was broken since the engine rendered the decal box in
the direction of the hit normal which meant that the viewer was looking
at a flipped version of the decal texture.

This fixes that by flipping the direction of the decal before passing it
to the GPU.

This also fixes the orientation for weapon decals which previously did
not take the orientation of the weapon that just impacted into account.

Goober5000 29a0736d34 fix missile detonation for computers with high FPS
There is a bit of code that detonates a missile if it misses impacting on a subsystem.  On Nyctaeus's Arachnas model, missiles could reach the center point of the main beam turret submodel without actually hitting any part of the submodel.  The fail-safe code would set the missile to detonate in that case, but on low-FPS systems the weapon would be able to actually hit the turret before it detonated.  On high-FPS systems, there is a clean miss.

This reworks the code to delay the missile detonation until it reaches the other side of the submodel, so it has time to hit some other part of it.  It also reduces the detonation time from 1/100 of a second (which is more than one frame on 120 FPS systems) to 1/1000 of a second (which is always less than one frame).

JohnAFernandez f21b1a7ace Multiplayer Resimulation for Client Fired Linear Weapons (Rollback) (#2788)
* 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

More importantly, it adds the hook variables with expected and user-friendly names, since 'self' and 'object' are not necessarily intuitive.
