Goober5000 05f71a30fb add some logging to waitAsync
Log when the context is created, completes, and is aborted.  Adds insight for the situation described in #4432.

asarium 0fb712ed39 Add full type coverage for return types and variables
This introduces type parsing for all types used within the scripting
documentation. This improves the generated JSON output and also
validates new code via the unit test.

asarium bb0631ab6e Support vararg specifiers in Lua documentation
This was the last thing that was missing for complete support of all
function parameter declarations.

To ensure parameter lists stay valid a unit test was added that will
validate the argument lists and cause the test to fail if they cannot be
parsed.

asarium 8d8f304514 Add more scripting APIs for the command briefing
This covers the various APIs needed for getting the last parts of the
new command briefing UI to work.

asarium 8fcb05bfd0 Add scripting API for custom execution context
This allows a script to create its own execution context so that it can
control when a coroutine is valid to play based on custom data.

Also adds a function which causes a coroutine to end in an error.

asarium 0d7ade0ca8 Validate scripting documentation type names
This will check if the type names specified in the argument lists of
scripting functions actually refer to valid type scripting names.

asarium ca27ae16f2 Use Antlr for generating argument list parser
This adds an Antlr grammar for parsing argument lists instead of using a
hand written parser. This allows to write much more complicated syntax
constructs and have all the code being auto-generated. It will also
produce a much more correct parser instead of having all those hacks in
the hand-written one.

This also adds (in addition to supporting the previous syntax) support
for function types along with support for them in HTML and JSON output
formats.

The ANTLR generated parser is included in source form so that it is not
necessary to have an ANTLR installation around if you are not going to
change the grammar. Also includes the necessary runtime code from Antlr.

asarium 016c07dc3a Add feature to execute Lua coroutines at specific points
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.

asarium 04174e00f8 Ensure Lua functions are executed in correct state
This will ensure that Lua functions will always be executed in the
correct Lua state. Since we now have multiple threads (which are
different lua_State objects) it is possible that the current code could
execute a Lua function in the main state instead of the thread that is
currently executing. This can lead to weird behavior and probably also
to issues inside Lua.

asarium 08c6e0d072 Introduce error state of promises
This is necessary after all to properly clean up resources if an
operation becomes invalid.

Also bumps Visual Studio version to 2017 on Appveyor.

asarium ebcf686cf7 Add Lua API for promises and async coroutines
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.
