fixed a_GetCVarFixed(str name)
fixed a_GetUserCVarFixed(int player, str name)

ZDoom doesn't provide a way to get a value of a float CVar as a fixed-point number.

GetCVarFixed and GetUserCVarFixed are implemented by using GetCVarString and GetUserCVarString to get the value as a string and converting it into a fixed-point number using Number parsing functions.
