'Script_DestroySignalEntryListHead' is the last function to be called before 'init.nut' is loaded and parsed. Defining "DEVELOPER" with value of "developer" convar allows us to utilize this constant in 'init.nut'.
In this retail engine, "DEV" is always zero, except for scripts.rson. I think Respawn Entertainment defined this as zero for production builds under each context except the global one.. To fix this problem, we define a new constant named "DEVELOPER", change all references in scripts that where DEV (now R5DEV due to legacy reasons to mitigate this problem), to DEVELOPER. When the game is launched with -dev, anything within #if DEVELOPER with compiled, like the development behavior of DEV.
* Fix all compiler error for GameSDK on S0 and S1.
* Remove some unused patterns and globals (launch performance gains of 100ms).
* Remove most duplicate patterns.
* Relocate globals from engine to a more appropriate location.
* Renamed some unknown vars to a more appropriate name (most of these where obtained a while back, but as we reversed more parts of the engine, some of these vars become known).
* Renamed some vars to fit the naming convention used in the SDK.
* Fixed pattern debug logging using the wrong pointer, thus displaying the wrong address.
The game uses 2 types, CSquirrelVM (mostly exposed to the VScript API of the engine) and HSQUIRRELVM (mostly used for internal squirrel functions like sq_pushbool etc..).
This refactor properly splits the CSquirrelVM* functions from the HSQUIRRELVM (SQVM*) ones. The functions have also been renamed accordingly and the prototypes have been adjusted to use the correct pointer type.
