- Check for sizeof()*sizeof(): This indicates that programmer misunderstood what sizeof() does: It does return the length in bytes of the given variable, not e.g. the number of elements in an array.

Message refactorization: checkstl.cpp

Refactorized resource files:
...
- Stored global information about cppcheck version and copyright string in a single resource.h file.
- Use macros of windows.h instead of numeric values for filetype, etc.
- Added versioninfo metadata to lib (#4275 )
- Removed VS resource editor code from resource files - these files shouldn't be modified with it to avoid information loss
- Renamed files to version.h/rc
- Encoded files as ANSI again - use escape sequences for unicode characters in literals (#4281 )

Tokenizer: improve the new 'skipTernaryOp' function by supporting GCC '{(var|num;)}' statement expression extension; improve 'Tokenizer::simplifyQuestionMark' by supporting simplification with 'case' before ternary operation, using skipTernaryOp to get colon and, most importantly, supporting indented '?:' operations.

Fixed: Tokenizer::simplifyLabelCaseDefault was careless with '?:' operator near 'case' adding the semicolon after the ternary colon.

Related to previous commit: if the '{}' parenthesis are found after 'case', don't skip them after continuing to the main loop or it will cause indentlevel mismatching.
