Changed handling of unhandled characters:
- Don't abort checking (reverts 42140b64888c7f313f6c9593447647c97de3bfa4)
- Modified error message: New Id unhandledCharacter, removed redundant line information, improved message text
Improved check: portability message when calling memset on a class with floating point numbers (#5421)
New check: Division by sizeof() as parameter to memset/memcpy/memmove/etc. as they expect a size in bytes (#5698)

Refactorizations in sizeof checking:
- Changed severity of sizeofwithsilentarraypointer to warning
- Made pointerSize message conclusive - there seems to be no reason for inconclusive
Removed newline from divideBySizeofError message
