The return value of `lua_tostring()` is NULL if (and only if) the string conversion failed. Many places in the code did not check for this situation, which led to the crash in #6290.
Fixes#6290.
* coverity - using `std::move` instead of copying, and change some parameters from value to reference
* coverity - fix or mark potential copy-paste mistakes
* coverity - various checking of parameter and return values
* coverity - miscellaneous fixes, and change some 'intentional' markers to 'false positive' markers
* make mission log dynamic
Change the mission log from a static array to a dynamic vector. This removes any chance of the mission log running into a limit (as regularly happened with the last mission of Shepherds before the limit bump) and also prevents strange mission bugs caused by culling obsolete entries.
This also unifies the API a bit by renaming the public `message_log_` function prefixes to `mission_log_`, removing the redundant `Num_log_lines` variable, and removing `Log_scrollback_vec` from the header.
Implements #5878.
* feedback
* refactor to reference rather than pointer
* base working version of unlimited debris types
* Proper FRED support
* make qtFRED handle asteroids properly
* fix qtFRED assertion
* further clean out MAX_RETAIL_DEBRIS_TYPES
* These should be sizes not POFs
* Move this to it's own method
* convert asteroid subtypes to a vector
* unlimit asteroid subtypes
* fix some global shadowing
* signed/unsigned mismatch
* Address feedback
This refactors the object_h struct to store objects as indexes rather than pointers. This is a prerequisite for making the collection of objects dynamic in the future. See also #6100.
Follow-up to #5800 and #5829.
* Exposes the New Flight Cursor Mode to Scripting
Thanks to #6136, FSO supports switching between two methods of flying. This PR exposes those settings and values to scripters. Tested and works as expected.
* fix aiming setting
* add reset position function
* cleanup setting pitch and heading
* one more cleanup
* update to enum support
* remove older version
* one more fix for setting flight mode
Considering that we have `ba.createRandomVector()`, we should have `ba.createRandomOrientation()` too. This is based on an algorithm devised by @Baezon.
Convert `sweep_duration` from seconds to milliseconds to work correctly with the timestamp system. Also clarify use of `game_get_overall_frametime()`, especially with `ba.getFrametimeOverall()`; and add `ba.getSecondsOverall()` to do what `ba.getFrametimeOverall()` allegedly did.
Allow the resize mode to be specified to `gr_set_clip()` without changing the active graphics-wide resize mode. Along with `drawStringResized`, this provides a shorthand to allow text to be drawn at different sizes, with the appropriate clipping regions, without requiring access to the `CurrentResizeMode` virtvar.
As requested by Event Horizon, this removes the limit on fireball types. The fixed array has been replaced with a vector and the relevant code updated accordingly. There is also a new version of `stuff_int_list()` to parse ints into a vector.
This also adds bounds checking for explosion animations that are parsed for ship classes, ship types, and asteroids, since previously there was no guarantee that the indexes would be in range.
To enforce type safety for arrival and departure locations, this converts them to enum classes. Various casts are added when appropriate to convert between the indexed and enum values.

This allows the skybox orientation and alpha to be accessed and changed through Lua virtvars, and also adds a sexp to change the alpha.
Unfortunately, changing the alpha has no perceptible effect on the skybox. This will need the attention of a graphics coder to figure out what might need updating.

Turn `Parse_names` into a vector and add SCP_string overloads of ship registry functions. Refactor calling code to use registry as appropriate. Remove an unused overload of `mission_parse_get_parse_object`.
* add extra ways to modify background elements in missions
This adds Lua API methods for getting suns and bitaps by index, as well as modifying their scale and position. This removes the need to completely add and remove a background element that only needs to be modified.
* big pruning of (int) casts
