These variables can be used for changing the behavior of the ade_ API
functions. However, they apply to all the ade_get calls so if there is a
call to ade_get_args from an ade_get_args call then it will reuse the
previously set values and produce incorrect results.
This captures those variables as soon as possible and then resets them
so that subsequent calls start with the default values for those
variables.
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.
This adds a Lua API for representing asynchronous operations and running
coroutines based on those operations comfortably. This is very similar
to features other languages have introduced such as C# or JavaScript. In
fact, the whole "promise" thing is derived from how JavaScript
represents these operations.
This is the initial and very basic system for supporting async
coroutines in Lua. There is no native support for running these
operations at specific points (they run whenever the awaited promise
resolved) or making sure they do not leak through different game states.
