allow cp_getvar(,CP_BOOL,NULL) to avoid insane usage
The third parameter is a pointer to the result value.
Frequently only the function return value is used,
(presence of nonpresence of the variable)
and the third parameter points to an unused variable.
Even worse, in several cases a dummy variable of incorrect type is used
for that purpose.
Thus,
allow the third parameter to be NULL, and kill those dummy variables.
