There's only one RETURN value on the C side (g_RETURN), which is also referenced
from Lua. Upon entering an event, its value takes on the per-event default one,
and its value when the event code finishes is passed back to the game.
Independently of that, its value is always saved and restored across event calls.

Instead of those of the translated code. Also some codegen tweaks and fixes.

We must not call these functions using the FFI, since the Lua state is
considered locked across such calls.

Preventing a continuously growing stack top and inevitable program termination.
Also, commonize the error handling to live on the engine side.

On the engine side (functions starting with L_), there are now the basic
parts like state creation and running code from strings and files.
The game and editor can add to that by e.g. loading whatever they please
into the state. Their functions start with El_ and Em_, respectively.
The Lua scripts still reside in source/lunatic, even for the common ones.
This is because they will be embedded into the binaries as bytecode or
compressed source eventually, so their location on disk will be irrelevant.
