cppcheck

New checks:
* actual initialization order of member variables is not the same as the written order. Use --inconclusive and --enable=style to enable this check.
* when first comparison is true, the 2nd comparison is always true. Example: '(x>5 && x!=1)'. Use --enable=style to enable this check.

we fixed many false positives and false negatives in existing checks.
