leakNoReturnVar: Don't break early ( #2095 )

There seems to be no reason for stopping checking the scope if a call to
free() is seen (or fclose() or realloc()), so just continue checking.
Also, if there are multiple arguments, check all, perhaps there are more
memory leaks to warn about.

leakNoVarFunctionCall: Use AST more ( fix #9252 ) ( #2086 )
...
Use the AST a little bit more to improve the check. In order to do so,
rewrite the check to work from the outer function first and then check
the arguments, instead of the other way around.
It also fixes Trac ticket #9252 , no warning is now given for
void* malloc1() {
return(malloc1(1));
}
This FP seems to be common in daca results.
It also makes it possible to improve handling of casts, for example
cppcheck now warns about
void f() {
strcpy(a, (void*) strdup(p));
}
But not for
char* f() {
char* ret = (char*)strcpy(malloc(10), "abc");
return ret;
}
These FP/FN were introduced when the check was switched to use the
simplified token list.
