This moves submodel rotation out of the AI pipeline and into object movement. With the exception of turret rotation (which remains in the AI code) this now allows all types of submodel rotation to happen in the same place. Many associated functions have also been cleaned up.
In addition to making the code cleaner and clearer, this will make it much easier for intrinsic rotations and new animations to be applied to non-ship objects, such as weapons.
This adds a mechanism for running generic operations at specific points
of the frame execution. This can be used by any part of the code an not
just Lua since it simply executes std::functions. It also adds an
"execution context" concept that specifies in which situation an
operation should be executed.
This is then used by the Lua Coroutines code for resuming coroutines at
specific points instead of always when the awaited promise resolves.
Part of modernizing the code base, Travis, at least, prefers defaults to be in the class definition instead of having multiple constructor functions have the same default values.
Allows jump nodes to use instrinsic/dumb rotation again by exposing the jump node class to the model instancing code and adding a check for it in modelread.
This was previously not enforced and some code did not call this
function at the correct time which caused crashes since data was not
initialized correctly. This adds a check to ensure that the function was
called and fixes the code that uses the model_draw_list.
This introduces a new mechanism for handling bit flags. Instead of using an int (or two, or three) to write bits into, this uses the std::bitset in a wrapper class that accepts an enum class as input. This means that certain classes of errors we've had a few of in the engine, where a coder used the wrong set of flags or checked them against the wrong variable (SF_STEALTH vs SIF_STEALTH, for example) can now be detected at a compiler level rather than not at all.
clean up some modelinterp code to not use memcpy() everywhere so it's more platform compatible and matches old code (Jens Granseuer)
NaN check to catch shards-of-death and prevent hitting an Assert() (Jens Granseuer)
fix jumpnode code to catch model errors and close a memory leak
make the call to bm_unload_all() after model_free_all() since we will get bmpman screwups otherwise
don't show hardware sound RAM when using OpenAL build, it will always be 0
print top-right memory figures in debug builds slighly further over when 1024+ res
