Mods like FotG do not use the FS style shield hit effects, and simply disabling the shield rendering and checking is useful with one simple global variable.
Tested and works as expected.

* const refs
* increment multi version
Two updates to the energy transfer system.
1. Previously, for fighters missing a system (e.g. shields), the energy would be treated as if all energy from that system was routed to the other systems. So, for example, a fighter's typical speed would be faster without shields than with shields. A new AI profile flag now treats the other systems as if the energy had not been transferred.
2. At some point in development, Volition intended the `$Power Output` ships.tbl field to affect ETS. A new AI profile flag now treats the power output as a factor of energy applied to energy systems.
The Input of `Trigger Radius` for curves within new particle effects was never hooked up for muzzle flashes, so this PR adds in the necessary lines to get it working. This allows modders to make a muzzle effect that can scale to the weapon radius through curves, and thus modders can simply make one curve scaled muzzle flash and avoid making a many muzzle flashes for each sized weapon that uses the same base effect.
Tested and works as expected.
If a ship changes class, the dockpoints on the new model may not match the dockpoints on the old model. This is most likely to happen when changing a docked ship in FRED to an incompatible ship class, but it can also happen when using the `change-ship-class` SEXP. So check the dockpoints, update them if they should be updated, and undock them if they can't.

* more cleanup
* range-based for loop
* Update comment
PR #6598 caused eyepoint normals to be used for viewing direction, whereas previously the host object's orientation was used for viewing direction. Since this could cause compatibility issues, return to the previous behavior and make the new behavior depend on a flag that is set in post-25.0 builds. (This only applies to eyepoint normals; eyepoint *positions* were respected both before and after #6598).
* Fix/cleanup using `intrinsic no shields` and ship loadout switching
The flag `intrinsic no shields` is used to allow switching between both shielded and unshielded craft in loadout. There is one edge case that was not accounted for though, which is that if a ship has no shields, and is switched to a ship with shields, the mission will start with that ship having a current shield strength of 0 and only slow get it's shield strength up via shield recharge.
This is not expected behavior, so this PR adds the extra conditional check that if that flag is on, then treat shield percent as full instead of empty. This ensures that switching to a ship with shields in loadout will begin the mission with full shield strength (instead of 0 and waiting for a full recharge).
Tested and works as expected. If desired I can put this behind a game settings flag, but I figured this was the expected behavior (and I'm not even sure how many mods besides FotG uses `intrinsic no shields`.
* also fix initial ets setting with intrinsic no shields
* format consistency
Remove the `n_quadrants` field because it is entirely redundant to the size of `shield_quadrant`. Also, be more rigorous about the difference between `shield_get_quad(i)` (which can fluctuate) and `shield_quadrant[i]` (which gives the exact quadrant strength). Finally add some C++ casts and move some checks to better places.
Use `std::unique_ptr` rather than `vm_malloc` and `vm_free` to handle optional strings in ship classes. This makes the code more robust and increases memory safety. This also allows several string variables to be consolidated in the ship class and weapon class script APIs.
Also add new `stuff_string()` overloads and a new `F_TRIMMED` string parsing type to handle the new fields and the string trimming done inside `stuff_malloc_string()`.
1. Use `const char *flag_desc` because constructing a SCP_string for each flag description is not needed
2. Make `VALID_FNAME` check for nullptr
3. Modify the signature of `coalesce()` to allow capturing of mixed `const` and non-`const` arguments
4. Use `std::for_each` (via `SCP_tolower`) rather than `std::transform` to fix compilation warnings
Most places in the code that use `vm_vector_2_matrix` do so on already-normalized vectors. Changing these to `vm_vector_2_matrix_norm` avoids redundant normalization.
1. Allow `ship_get_eye` to be used for any objects, not just ships
2. Remove the unused `from_origin` parameter and add `local_pos` and `local_orient` instead
3. Simplify the implementation and take advantage of upgrades to `model_instance_local_to_global_*` functions
4. Consolidate `ship_get_eye_local` into `ship_get_eye`
1. Refactor `num_hits` to `num_sparks` and `MAX_SHIP_HITS` to `MAX_SHIP_SPARKS` to be consistent with their current (since FS1 pre-release) usage.
2. Remove the unused `HP_SCALE`.
3. Always initialize at least one spark pair. If `choose_next_spark()` was entered when `num_sparks` was 1, `num_spark_pairs` would be 0 and none of the spark pairs would be initialized. Consequently, accessing the pair at index 0 would return garbage data.
4. Iterate through `num_spark_pairs` when counting the indexes, rather than the hardcoded (and incorrect) magic number 6.
Fixes a crash discovered by Dawnesya that can only occur when a ship has both the "fighter" and "cruiser" flags. Normally, fighters never enter the `choose_next_spark()` function and 'big' ships always have at least 3 sparks.
* Make Cockpit Deferred an In-game Option
After testing and consideration, this PR adds the Cockpit Deferred setting to the in-game options. Also adds a parser to the new default_settings.tbl.

* Setup trigger radius

Make `SCP_vector`, `SCP_list`, `SCP_set`, and `SCP_multiset` subclasses of their STL counterparts. This allows helper functions to be added to each, including the `contains()` function which is not available until C++20. (This has minor effects on other parts of the codebase that treated `SCP_` and `std::` as synonyms.) Since there is now a nontrivial amount of code that needs to be in a .cpp file, create vmallocator.cpp.
Note that `SCP_string` truncation has been refactored to use length rather than C-string size to be consistent with other `std::basic_string` functions.
Also, remove some enum class hashing code which is no longer necessary now that the codebase is at C++17.
Several changes related to the volumetrics model fix:
1. Update the `model_load()` prototype with better parameter names, including a new `ErrorType` enum defined in pstypes.h
2. Update the `MIN`, `MAX`, and `CLAMP` macros, all of which were susceptible to performance issues because they duplicated their tokens. This could cause functions or calculations to be re-run unnecessarily. Since the codebase is now on C++17, `std::clamp()` can be used.
3. Update the rest of the codebase to fix any associated issues.
Make these convenient functions even more convenient:
1. Change `object_get_model()` to `object_get_model_num()` and `object_get_model_instance()` to `object_get_model_instance_num()` to more accurately reflect what they do
2. Add new `object_get_model()` and `object_get_model_instance()` functions to return `polymodel*` and `polymodel_instance*` values.
* Add Mod Option to Limit 'Show Ship' when Toggling Cockpits
FotG uses cockpits and 'show ship', and also provides a way for players to toggle off cockpits. Unfortunately, if the player disables cockpits, 'show ship' still appears and looks very odd (since it appears the player is flying a ship with a hole in the center where the cockpit would be). Other mods have made entire ships with their cockpits, but FotG needs to use 'show ship' to match team colors and moving external ship animations.
This PR adds a game_settings option that allows mods to set to only use 'show ship' if cockpits are enabled.
Tested and works as expected.
* simplify logic
* fix typo
This has been broken ever since commit 6c17ef09ab in 2005. Since `get_hull_pct()` did not return negative values, `percent_killed` was always 0. Allow negative values in this case.
There is a rather large design flaw in FreeSpace debriefings... debriefing SEXPs can refer to in-mission ship data, while all ships (and all objects) are deleted as soon as the mission completes. Specifically, `obj_delete()` is called which sets all objects to `OBJ_NONE` and marks them as freed, although the data still exists in the various arrays. This is the use-after-free problem, but applied to the in-game object system, rather than memory accessed by pointers.
It's probably best to defer fixes to an as-needed basis. As for hitpoint SEXPs, this change updates them to use the object and ship references from the ship registry, since the ship registry is not cleared by the time the debriefing is loaded. (Using `objp->instance` and `shipp->objnum` at this point would be problematic.) Since subsystems are also cleared at this point, this also updates the warning messages in those functions.
Fixes an Assert seen in debug mode in Inferno.
