1)change tokAt(1|-1) with next()|previous() with conditions where necessary;
2)change strAt(1|-1) with next()|previous()->str() with conditions where necessary;

4)change simplifyFuncInWhile implementation because it was too slow and stupid.

Add check for cppcheck's internal API usage ( #3263 )
...
First checks:
- Simple pattern used inside Token::Match()
- Complex pattern used inside Token::simpleMatch()
The checks get enabled by passing "--enable=internal".
It's not included in "--enable=all".
If you see something that needs further tweaking, just go for it!
