- moved parts of the render setup out of the separate render functions.
Things like particle and polyobject linking were duplicated several times for rendering different things in different renderers.
These things only need to be set up once before the renderer is started so it makes a lot more sense to consolidate them into one place outside the actual rendering code.
This had two different flags that were checked totally inconsistently, and one was not even saved.
Moved everything into a few subfunctions so that these checks do not have to be scattered all over the code.
There is no need to do this deep inside the renderer where it required code duplication and made it problematic to execute on multiple levels.
This is now being done before and after the top level call into the renderer in d_main.cpp.
This also serializes the interpolator itself to avoid problems with the Serialize functions adding the interpolations into the list which can only work with a single global instance.
The shader timer may be taken from the primary level for the entire scene, because it will always be the same for all levels in a set.
The camera textures need to be prepared for all levels.
Since currently there is only one level, this will obvciously only run once on that level for the time being.
This is mainly used for CCMDs and CVARs which either print some diagnostics or change some user-settable configuration.
Depending on serialization order is not a good idea here, so now it's no longer stored as a parent in the main level script but explicitly checked for when looking for a variable.
This is what should be audible. To prevent other levels from playing sound, all entry points check whether the sound playing entity belongs to the current UI level.

This was done to ensure that this code only runs when the thinker itself is fully set up.
With a constructor there is no control about such things, if some common initialization needs to be done it has to be in the base constructor, but that makes the entire approach chosen here to ensure proper linking into the thinker chains impossible.
ZDoom originally did it that way, which resulted in a very inflexible system and required some awful hacks to let the serializer work with it - the corresponding bSerialOverride flag is now gone.
The only thinker class still having a constructor is DFraggleThinker, because it contains non-serializable data that needs to be initialized in a piece of code that always runs, regardless of whether the object is created explicitly or from a savegame.
Doing this intermingled with the thinkers is highly unsafe because there are absolutely no guarantees about order of execution.
Effectively it ran these commands right in the middle of the playsim which could cause all sorts of synchronization issues, because CCMDs are part of the UI, not the playsim.
- pass a const string to AddCommandString.
This function manipulated the input buffer, leading to all sorts of code contortions to make sure that the passed parameter is clean for that.
This function will now create a copy of the passed parameter which it can manipulate without complicating its calling code.

This doesn't really write out any info for the pointer, if the level does not match it just errors out.
This is both for quick detection of badly used level data and for automatic restoring of the pointer from the serializer's working level.
This also removed the temporary workarounds in DAutomap and DLevelScript to restore these pointers when a savegame is loaded.
This was a relatively cheap change but removes a significant batch of references to the global variable, only making the entry points to the ACS interpreter relevant.
UI always runs on the primary level, so this does not need the ability to operate on multiple levels. Additionally, this can later be set to null when running play code so that scope violations result in an abort.
This also changes the action special interface to pass a Level parameter to the separate functions and makes a few other minor adjustments to the polyobject code.
This should later be done for everything else as well, but the map loader should really be free of global dependencies ASAP.
Also replace TThinkerIterator<AActor> with FThinkerIterator globally because this only adds pointless type checks - with all actor subclasses being scripted this class has become redundant.
This entered the code path which warned about ambiguous use of variables in action functions and as a result ran afoul of subsequent error checks.
Since ZScript has no global scope resolution operator, this needs to ignore all non-static class symbols and try to look up any of these as global identifiers.
This caused bad calculations with CMF_OFFSETPITCH. Note that to compensate for the fix, the SphericalCoords function had to have its own inversion of the value removed so that it calculates the same result as before.
Apparently some people have to pass positive numbers in here to get a negative pitch, e.g. 350.0 instead of -10.0...
This prevents clamping of such out-of-range values that would otherwise constitute valid pitches with the wraparound in place.
Using global variables for this is bad, and it didn't even catch all cases. Now a node build is only considered successful if everything is set up successfully.

- It was calling the fallback aiming in the wrong place when it should have been outside the speed check.
- Credit to _mental_ for the base code, but no gotos involved.
There are several places where a temporary change of light mode is needed, all these made this change in the global level struct. Now the change is only local to the active draw info.
If we ever want to refactor the global level data these must not reference the 'level' variable.
The main parts of the map loader cannot use this information, because it can only be created after running the node builder, so it got its own set of index functions instead.
Visual C++ will never statically initialize a class instance where a member field has a default value set, so the DEFINE_ACTION_FUNCTION variants without a direct native call need to be handled differently. The easiest way to do this is to leave out the nullptr default and omit the value in the initializer list. For trailing fields this will always get them nulled.
Also tried to sort them by renderer use but that turned out to be without any performance effect, even though the struct is a bit better aligned now and several bytes shorter.
I have to wonder why it had to use such a complicated implementation that provided no advantages whatsoever.
The new code is just 1/5th of the old one's size and much closer to Hexen's original implementation which also was a simple array but with no means to resize the queue.
This involves passing the level explicitly to many functions. What was done here may seem a bit excessive but at least it covers everything.
Most importantly, the global ActiveThinker pointer has been moved into FLevelLocals and is now getting tracked properly by the level without using dangerous assumptions about how the game organizes its data.

- update shadowmap AABB tree after R_SetupFrame for proper frame interpolation
Unlike the other classes, the places where variables from this class were accessed were quite scattered so there isn't much scriptified code. Instead, most of these places are now using the script variable access methods.
This was the last remaining subclass of AActor, meaning that class Actor can now be opened for user-side extensions.
This was the only code using the ViewBob member variable.
This also moves the range check for this variable to its application, because a badly behaved mod can just as easily change it at run time instead of just setting an absurdly large value in the class definition.
Since these can be changed on the placed light actor they have to be read from there, so this is now a pointer in FDynamicLight, just like the other properties that can be user-changed.
Also did some cleanup on the interface so that external code doesn't need to dereference the lightflags pointer but can use utility functions for all flags.
backtrace functions are not present in all libc implementations. Cmake has
module to add external libraries into build if needed so use it to fix build on
Unix systems without backtrace in libc.
ReadString allocates a buffer, so saving it in a local variable and then forgetting it will not free the buffer afterward.
(This should probably be refactored to use some safer methods to read the string than this old-school method...)
This should be less of a drag on the playsim than having each light a separate actor. A quick check with ZDCMP2 showed that the light processing time was reduced to 1/3rd from 0.5 ms to 0.17 ms per tic.
It's also one native actor class less.
Since the SpawnedThings array is still available when polyobjects are spawned it makes no sense to create an expensive linked list in P_SpawnMapThing.
This can be done far better by scanning through the array again and collect all matching items in a second array.
This thing made sense when GZDoom and ZDoom were separate projects to avoid having to change some core files for the added options.
Now, with only 3 ones remaining, one for FraggleScript and two for Extradata the overhead here is just too high. The 3 variables can just be moved to level_info_t without carrying along this much baggage.
Since actors are being spawned before the renderer gets set up this needs to fully initialize the list before spawning the actors, then take it down again for creating the vertex buffer and then recreate it.
