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.
Return the current supernova stage. This sexp, in conjunction with mission cutscene editor, makes it possible to reproduce the FreeSpace 2 end-of-campaign cutscene behavior purely in FRED. The resulting cutscene section looks like this:
```
$Campaign End Cutscene: endpart1.mve
+formula: ( true )
$Campaign End Cutscene: endprt2a.mve
+formula: ( < ( get-supernova-stage ) 3 )
$Campaign End Cutscene: endprt2b.mve
+formula: ( >= ( get-supernova-stage ) 3 )
```
Also add a new status subcategory and fix newline behavior when saving the cutscene section.
Fixes#6657.

Copy existing code from change-ship-alt-name into new sexp
change-ship-display-name and likewise from OP_SHIP_CHANGE_ALT_NAME to
new OP_SHIP_CHANGE_DISPLAY_NAME. Create new blank function
"sexp_ship_change_alt_name_or_callsign" and a function for multi too.
When an orientation matrix is constructed using one or more vectors, all such vectors must be normalized. Previously, the code did not enforce this for matrices parsed from a mission or table file. Although FRED will use correct matrices, it also truncates floating point values to six decimal places, so non-normalized vectors might be written to the mission file as happened in #6632. And there is always the possibility that someone could manually edit the mission file to corrupt the matrices.
While we're at it, per suggestions from Asteroth and qazwsxal, make sure the matrix is orthogonal as well. The `vm_fix_matrix` function handles all relevant calculations.
Fixes#6632. Follow-up to #6596.
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()`.
Upgrade `parse_get_line` to detect all three EOL types: CR, LF, and CRLF. The function is now more robust against line ending mismatches and will now also warn the modder if a file contains mixed line endings.
Fixes#6395.
1. Trim trailing whitespace on any property values, just as leading whitespace is trimmed. All places where `get_user_prop_value()` is used implicitly or explicitly require this.
2. Warn the user if an invalid `$special` value is parsed. This would have caught #1, and will now catch related errors, such as misspellings, in the future.
3. Enhance `string_lookup()` with the ability to print the list being searched, if desired. Remove an unused version of `string_lookup()`.
4. Check for lower-detail submodels being recognized as subsystems.
Allow `stringcost()` to use a specified function to check equality, and provide both case-sensitive and case-insensitive sample functions. Use case-insensitive checks for sexp operator lookup.
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.
Add "goal" as a type recognized by scripted sexps. Also add `mn.Goals` as a collection to complement `mn.Events` and move the goal type to goal.cpp and goal.h to match event.cpp and event.h. The new `mn.Goals` collection contains the same data as the existing `Objectives` collection in the briefing UI library, so the latter could be deprecated.
This type for subsystems is analogous to the shipname type for ships. Sometimes it is useful to refer to a subsystem even if its parent ship is not present. Whereas the subsystem object would be invalid, the subsystemname string still contains the string that the mission designer specified.
Relatedly, upgrade the parsing of `+Parent Parameter Index:` to be checked on both parented and non-parented parameters. This will help both modders who put the field in the wrong place and programmers who may want to add a parented parameter in the future.
Any NaN encountered in the evaluation of functional-if-then-else should be isolated to the branch on which it occurs. Fixes#6536.
Also improve some help text for clarity.
