					 y_inline - PAWN inline functions.
					===================================
Description:
	This library allows a user to write inline functions in their script.  It
	first detects all inline functions and generates data on them, such as
	parameter counts and addresses.  When an inline function is passed in code
	its current context data is stored.  Finally, when an inline function is
	found to be called at some point its current local stack is stored in global
	memory.  When the function actually is called, the stack is restored, and
	additional parameters which are the inline function parameters, are passed.

#if 0

// This:
inline func(a, &b, c[100])
{
	// Inline function code.
}

// Becomes:
static const func[]="func:.....";if(I@E(func))for(new a, b, c[100];I@F();)while(I@L(0,-1,100))
{
	// Inline function code.
}

// Which is:
static const
	func[] = "func:.....";

if (I@E(func))
{
	for (new a, b, c[100]; I@F(); )
	{
		while (I@L(0, -1, 100))
		{
			// Inline function code.
		}
	}
}

// Translated:
static const
	func[] = "func\02;" #FUNC_ADDRESS #PARAMETERS #INTERNAL_RETURN #PREVIOUS_FUNC_NAME #PARENT_SCOPE_START;

if (Inline_Entry(func))
{
	for (new a, b, c[100]; Inline_Allocator(); )
	{
		while (Inline_Main(INLINE_TYPE_VAR, INLINE_TYPE_REF, INLINE_TYPE_ARR(100)))
		{
			// Inline function code.
		}
	}
}

// Run-time modified to something like:
goto somewhere_after_this_func;
func(parent, parameteters, a, b, c[100])
{
	new parent, local, variables;
	// Inline function code.
}
// Multiple inlines in a row are combined in to one big jump.
